It wouldn't make a difference inititially when just measuring solar since solar generation is balanced. If the system doesnt have any revenue-grade meters installed, the response includes an empty intervals array. Some may view this as a draw back. Since installation the system has shown an intermittent error: "Meter Issue. (I have observed bogus values for 'production' and 'consumption' in range between 0 and 2). If there's voltage over 0.2 volts in any wire or connection, check for corroded, damaged or loose wires. 0000033107 00000 n Attributes that are times are named accordingly (e.g., operational_at, last_report_at, start_at, end_at). I have an Enphase system but it only has production and the blue bars are in the same orientation as in your chart. The darkish overcast looked like possible little snow storm coming. It was like this for a Envoy On the MyEnlighten desktop application, the icon to the left of your system name tells you how your system is doing.

I wonder if they can tweek low light efficiency for me? I hope we can see it being updated in Home Assistant as well soon. between the phases to allow the Envoy to communicate with all of the Enphase devices in the system. Currently I do not have TOU rate pricing. If the consumption measurements received by Enlighten do not appear to include storage activity, there are two possible wiring issues that can cause this: The Meter Issue status will continue to display until Enlighten receives 24 hours of meter measurements that indicate the problem has been addressed. the blue wire goes to a splice pack under the carpet under metered_production_readingtime Long explanation that I don't think I have any unique problems, just that the mppt curve does not track well below 28% of peak array power. Could this have been fixed in a later firmware revision? ct_enabled with default value True (requires no changes in existing client code). My blue bars show production and yours appear to show consumption. issue with envoy meter measurements [V6Pq ]_,.7bK~lqq}e~Y4e[./7ew,X*k9IAhR4wgf e EZ%%da'6[kV^n7H"]c$)yRT@S1A| _|w,#G(@!{;?

I removed the inverter data and right now the values are zero due to no sunlight, but you should get an idea of what would be sent to Home Assistant once that sensor code is updated. I see information in /api/v1/procuction and /api/v1/production/inverters being updated every 5 minutes. 0000048797 00000 n Installing the Enphase Envoy-S Metered endobj Parameter order does not matter in any request. 0000339393 00000 n Announcement: Effective October 1, 2023, Enphase API will only support TLS 1.2 and will not accept any applications on older TLS versions, Announcement: The end of life for Enphase API v2 has been extended from August 15, 2022 to September 30, 2023 0000026874 00000 n (latter number is lower but 'R' looks higher/newer than 'D'), Can you please add the following parameters for reading timestamps? Exactly: I have only CT's installed for measuring Consumption "CT's" is plural but consumption/eim/activeCount only shows 1. As an example, NSW residents previously had gross metered solar systems. My consumption only power-factor when I look at it from the installer toolkit Intervals are 5 minutes in length and start at the top of the hour. Now I have to get this included in a bugfix-release for Home Assistant as 2020.12.0 includes the envoy_reader with the bug. If the total duration requested is more than one day, returns one day of intervals. I wonder if that is why your blue bars are labeled production but look like they follow a consumption pattern?

Interesting, /ivp/meters gives some configuration/status information such as phaseCount and phaseMode that I haven't seen elsewhere: http://envoy.local/ivp/meters/readings seems to be very useful. I have assumed it was 'Voltage and Current Metering' using the ohm's law variables (P = EI), so EIM. When this condition is detected, the response code is 500 and the response body is: Returns a time series of energy consumption as measured by the consumption meter installed on the specified system. /api/v1/production/inverters (serial numbers have been obfuscated): /api/v1/production "wattsNow": 2236 When the filter is system_name, the results include all systems whose name includes the requested substring; for example, given the following system names, The filter ?system_name=Green would return. Yes, I do want and think the values for both inverters and eim should be accessible if available. % @jesserizzo What do you think about moving all of the production polling to /api/v1/production and only use /production.json for metered production and consumption data? Returns performance statistics as measured by the revenue-grade meters installed on the specified system. 0000140307 00000 n Handle Envoy S (and Envoy IQ) without CT's as 'endpoint_type' "P" instead of 'endpoint_type' "PC". @lnlp I'll release the new version on pypi this weekend and open a PR on the Home Assistant side as well. It is important to understand these differences when installing Envoy CTs. All times are GMT-5. "[}QXD/jD NCrncVa @L*23m Depending on if the Envoy is configured as Net or Total Consumption could impact the values you are seeing in Home Assistant. Enlighten declares a Meter Issue () system status when it detects a possible problem with the CT or storage measurements. Though I wonder if something like this would solve the problem, Add a function called hasMeteringEnabled() which will return True if production[1]eim activeCount is >= 1 else False, envoy_reader/envoy_reader/envoy_reader.py. I'll return values with a decimal. 0000010645 00000 n And for the nice to have wishlist: For example. I really like to give the user all of the data and let them figure out what they want to use. In cases such as these, the response code is 422 and the response body includes an error reason as well as the parameters used to process the request. The iso8601 format returns all temporal values, whether dates or times, in an ISO 8601 time format including timezone offset; for example 2015-05-05T00:00:00-07:00 is midnight on 5 May, 2015, in Pacific Daylight Time. Enlighten declares a Meter Issue () system status when it detects a possible problem with the CT or storage measurements. I'm following the current convention that was previously coded. I just wonder is there a configuration of the Envoy where a production CT is installed without a consumption CT? If your system is producing less energy than your installer estimated, youll see a message like this: Click Learn more for information on how to get help with the problem. stream They can always filter these values out in Home Assistant by specifying which monitored_conditions they want to see. |JU\"K2b Well occasionally send you account related emails. Use production_meter_readings or energy_lifetime instead. In my comments above, I was arguing for the case to still be able to get the inverter numbers even if metering is enabled. And the metered_* parameters come from the appropriate section of /production.json that contains type of eim. This "readingTime" is probably accurate enough to be used as timestamp for data in /api/v1/production. 0000012488 00000 n This is a bit more than one yard. This has to either be an issue with where the consumption ct clamp has been installed, its orientation (arrow direction) or with a software setting on the envoy or a combination of all 3 possible causes. 0000010160 00000 n The Enlighten Systems API Energy consumption CT monitoring for home solar systems I have had the production CT installed from the beginning and I just now got around to installing the consumption CT's. Unrecognized parameters are ignored. metered_consumption_readingtime, How about simplifying 0000023514 00000 n If the response includes trailing zeroes, such as [909, 4970, 0, 0, 0], then no energy has been reported for the last days in the series. After period_end, you can make another request. (Maybe you are mistaking with the cloud API's update frequency?). and When the query parameters include production=all, returns meter and microinverter-measured time series: Returns a listing of all active Envoys currently deployed on the system. String attributes must be URL-encoded. Refer to the Release notes page for any recent changes to the Enlighten API. In that case, the response code is 500 and the response body is. If the system doesnt have any consumption meters installed, the response includes an empty intervals array. If you don't see any voltage pulses, replace the sensor. For example, midnight on 5 May, 2015, in Pacific Daylight Time is 1430809200. Application plans have minute and month limits. WebThe Envoy brings you the real-time, module-level performance data that makes it easy to monitor your system or fleet from any web-connected device. I'm not sure on this one. When the filter is reference, both reference and other_references are searched. Ideally, the user should be able to specify and track either or both from Home Assistant. The circuit passing through the consumption CT does not include AC Batteries. Well sorry to say but there was a bug in the code. WebThe use of any other type of CT will result in incorrect power measurements, and may permanently damage the WattNode meter. Some may view this as a draw back. envoy_reader should handle all these (4) situations correctly. The data from my Envoy (3-phase, no CT's) looks like this (pretty-printed): Based on above it appears that /production.json is not going to contain data for each phase separately (in 3-phase system). And when envoy_reader reads its data from the "eim" section shouldn't that be done for each phase separately and then summed to get totals for all 3 phases? Model: Consumption Production Consumption Consumption Clamp Quantity Error: Failed to fetch Details Other than reducing http calls to the envoy device, is there another benefit to pull the production data from the two pages rather than one? In general, a Meter Issue indicates a system where on-site maintenance may be required. The production or consumption measurements received by the Enphase Cloud are negative. If the system has both production and consumption CTs installed, you can see which meter is affected by checking the meter status on the Devices screen. Example: It is possible to request a subset of the systems list. Envoy firmware gets updated by Enphase automatically. To enable correct operation of the Enphase Home Energy system components (including the Enphase AC Batteries), the Envoy must correctly measure the current flow across the electrical circuits via the CTs. If you are upgrading with Enphase microinverters to an existing string inverter installation, follow one of these options: All solar AC cables must pass through the Production CT. For /api/v1/production the timestamp can be read from production.json "inverters" section. period_start and period_end tell you when the minute (in this case) started and when it will end. 0000128138 00000 n If the answer to the above question is true, then it would also be useful to have inverter_lifetime_production in addition to metered_lifetime_production. For just the powering of the Envoy a single phase would be sufficient. For a 3-phase installation I would need to buy 4 additional CT's while consumption and production data is already provided by my smart electricity meter (via DSMR P1 port). In my situation (ct_metering_production is False) the production value is read correctly from the production/inverters section in production.json. You can check the systems status in the meta attribute of the response to determine when the system last reported and whether it has communication or metering problems. I'm wondering if someone with a functioning pre-IQ envoy could browse the production json value and post your results. measure resistance from orange wires to large power terminal under rear seat.. they should all be under 10ohms and not change when the wires are pulled on. So this voltage is apparently read from L1 on the 'power input' connector. For example, a request for 08:01, 08:08, 08:11, or 08:14 is treated as a request for 08:00. Andrew Mitchell's Enlighten Manager Mastery video. 1.0 5 Additional Features Additional features include wrong wiring detection, such as inversion meter types, electrical connections) can vary across Australia. When using Envoy S without having CT's enabled then production data in envoy/production.json is NOT updated. So I swapped the leads on the Envoy for the consumption CT's and have been monitoring all day and the data looks good. All measurements are in Watt hours. It appears that this value is probably taken from the same L1 input, but its value differs few-thousand's of a volt. meter_issue One or more meters on the system are reporting unusual Planning and installing consumption monitoring An Enphase team member may follow up with you about your feedback. I just wanted to let you know the logic might not be working as intended. 0000029406 00000 n When fixing wires and connections, aim for a (My solar installer did not connect L2 and L3 on the 'power input' connector so I am currently unable to verify for ph-b and ph-c.). Enphase Ensemble Systems. 0000339432 00000 n If the system does not have a meter, returns 204 No Content. Some batteries havent charged or discharged recently. If your system has AC Batteries: Some batteries havent charged or discharged recently. You may pass a limit parameter to the request, which sets the page size for that request. Theoretically one of the two CT wires could also be used for measuring voltage. Each envoys element includes the following: Returns a list of systems for which the user can make API requests. One case that is not handled, if you want the inverters current production and WH lifetime production, with metering turned on, you can only get that from production.json. For more details, visit 0000017403 00000 n Enphase Solar PV Installation Certification Training Flashcards I tested your modified envoy_reader with my Envoy-S Metered Multiphase with metering disabled (no CT's). 0000411029 00000 n Will there be / shouldn't there be 3 separate "eim" sections, each for one phase? These come from mainly 3 pages (excluding Envoy running <3.9 firmware), I would propose removing the original consumption parameters and adding additional parameters (lets prepend them in this example with metered_*. It would be nice if other useful parameters e.g. How do I troubleshoot a Meter Issue system status? My 8x320W=2.56 kw mono array gets the IQ6+ inverters running at pf=1 at 700 VA. In the "inverters" section? Actual Production that gets updated is available via envoy/api/v1/production however. 0000017266 00000 n Perhaps for compatibility there should be three available entities for the wNow values in Home Assistant: Having these three elements would allow the user to override Envoy reader's choice if necessary as well as track both on systems with CTs if the user chooses that.

Can you open a new issue (enhancement) to track this one? I've tried switching polarity on the CTs, and moving them around, but I can't get it into a real range. If you are not sure how to meet these requirements, please contact api@enphase.com before you launch anything. All API requests require your API key and a user_id. measure resistance from black wire at lgm connector (while disconnected) to ground behind side panel inside rear cargo area. Gaps in reporting are not filled with 0-value intervals. For example, a request for 08:01, 08:02, 08:03, or 08:04 is treated as a request for 08:00. Contact us for sales, quantity discounts and expert reviews for the Enphase CT current transformer for Envoy. The heating system is just resistance heaters on that car so it's like a giant toaster oven. If the meters milliamp scale goes up to 500mA, then I In other words, if you explicitly want to access that data for the inverters whether or not metering is on, production[0] is the place to get it. If the message persists and is not due to unusual production or consumption conditions, contact your installer for help. This indicates that you have made too many concurrent requests. How do I troubleshoot a Meter Issue system status? | Enphase Note: my CTs are currently disabled.

Returns the energy production of the system for the month starting on the given date. 0000375146 00000 n It could be the CTs are plugged into the wrong socket. For a Net metering arrangement (load with solar), the Consumption CT must be positioned to measure the site loads AND all of the solar export. Note: If a system does not include a given device type, that key is left out of the returned hash. Instead of /stream/meter has anyone tried /ivp/meters/readings? WebEnvoy-S Metered and Envoy-S Metered Multiphase (IQ Envoy) are both black but the Envoy-S Metered Multiphase has the cover screw on the right side while the Envoy-S I did not check (yet) where the come from and/or lead to, I did not check (yet) where the come from and/or lead to. My /api/v1/production/inverters inverter data is already properly read and output by envoy_reader (I can see the values in Home Assistant). 0000268009 00000 n Remote problem-solving The Envoy lets you pinpoint performance issues instantly and resolve them remotely, before they get in the way of system performance. 0000410990 00000 n 0000093464 00000 n Envoy reader makes an assumption depending on the type of Envoy whether CT metering is being used. Requests for times that do not fall on the 15-minute marks are rounded down. WebC. The installers could have put it on the wrong leg. Then a question, does the api return the eim values that is got from the envoy even when the activeCount = 0? metered_consumption wNow: 0.836 (gets truncated to 0). This is just low sun with overcast far to the side of the array. production.json eim only shows an aggregated number. EIM - Your guess on the meaning of the acronym is 'electrical induction metering' is possibly correct. Envoy S Production data is not read / read incorrectly when current transformers are not enabled/installed [bug], https://thecomputerperson.wordpress.com/2016/08/03/enphase-envoy-s-data-scraping/#comment-5838, Add production_readingtime and consumption_readingtime output parameters, Add consumption_ct_metering_enabled and production_ct_metering_enabled output parameters, Support reading values of consumption and production per phase, The envoy is configured without CT metering and the user wants WH totals for today and 7 days which aren't available in. In your case it should be "load with solar production" as the solar breaker is on the load side. WebWhen used with an Envoy S Metered or IQ Gateway, the Consumption Current Transformer (CT) enables home energy consumption monitoring. An alternative to polling /api/v1/production is to use production.json type == inverter whLifeTime and compute the delta locally, either within envoy reader, or Home Assistant. Here's what mine looks like: I think the negative power factor happens when you're sending power back to the grid, but I could be wrong. This page was generated at 03:27 AM. All rights reserved. I would like some input from @jesserizzo and others. This endpoint includes entries for every production meter on the requested system, regardless of whether the meter is currently in service or retired. 0000032798 00000 n For example, there are 100 centimeters in a meter. All rights reserved. We are available to look at live beta sites, screenshots or ad-hoc apps to help guide your development. Returns summary information for the specified system. Have you tried flipping the CTs 180 degrees? CT metering can be turned off even on newer Envoys if the CTs aren't installed or are installed incorrectly. My guess is that data from /stream/meter on your envoy will report realistric (true) voltages for all three of data/production/ph-a/v, data/production/ph-b/v and data/production/ph-c/v. The start date must be at least one month ago. 9 kW solar, 42kWh LFP storage. Because envoy_reader appears to read them from /production.json where the names are present but their values are 0 and do not get updated. Enphase seems to have a bug where they sum the amperage values for each phase and then multiply that by 240 to get VA. That's wrong and results in a VA value for TOTAL CONSUMPTION that's upwards of twice what it should be. A CT is installed and Metering is only monitoring Production. Production CT Installation on sites with multiple solar systems. Better ($) electric cars are using heat pumps more effectively to heat. So it looks like you need to join with /ivp/meters based on eid to know what you are looking at and whether it is enabled. Maybe I should have been a little clearer but Home Assistant is not letting existing integrations to change their monitored_conditions. Active does not imply that the device is currently reporting, producing, or measuring energy. Commonly, the reading will be within 30 minutes of the requested end_at; however, larger deltas can occur and do not necessarily mean there is a problem with the meter or the system it is on. The manual is not clear about why all 3 phases should be connected to the 'power input' connector. Envoy Status Returns the last known odometer reading of each revenue-grade production meter on the system as of the requested time. This requires an alternative arrangement of the CTs for correct measurement. Maybe this is Envoy-S Metered (Multiphase) and or firmware version dependent? Not sure what the actual url for the page is though. Envoy-S Metered and Envoy-S Metered Multiphase (IQ Envoy) are both black but the Envoy-S Metered Multiphase has the cover screw on the right side while the Envoy-S Metered has the cover screw on the left side (like Envoy-S Standard). Enlighten supports up to two versions of the API at any given time. When I look into the error, it was not apparent to me the problem. This does not require to connect all 3 phases to the power connector. I'm still looking over the code and the different paths taken and the different types of envoy devices with and without features. Sign in Electrical system: 3-phase 230V. WebThe Envoy-S monitors the microinverters that are connected to the PV modules. Looks like you are checking for not set/zero vs. checking activeCount. Or atleast get reporting working for all attributes for each hardware platform. Each system element includes the following: Return values for status include the following, and are listed in priority order: Returns a listing of active devices on the given system. Data coming from /api/v1/* is updated every 5 minutes. trouble with enphase envoy consumption measurements If there is an issue with the Envoy meter measurements, youll see a message like this: If one or more of your AC Batteries hasnt charged or discharged for the last 72 hours, youll see a message like this: This may not indicate a problem, especially if there hasnt been enough sunshine to produce energy that exceeds your homes consumption, or if your homes energy use has gone down to the point that the batteries dont need to discharge. A difference of 1 Watt, which may be caused by a rounding error, or by a small difference in moments of measurement.
