issue with envoy meter measurements

All API requests, regardless of version, are throttled according to the limits of the application plan you chose when signing up for an account. 0000011718 00000 n Today is medium overcast so that is adding to low production. If the system doesnt have any revenue-grade meters installed, the response includes an empty intervals array. Meters are abbreviated using a lower case "m" in measurements. In 'case B' one may wonder why the 'power connector' on the left exists and allows to wire all 3 phases. This "readingTime" is probably accurate enough to be used as timestamp for data in /api/v1/production. Attributes that are times are named accordingly (e.g., operational_at, last_report_at, start_at, end_at). So I swapped the leads on the Envoy for the consumption CT's and have been monitoring all day and the data looks good. Here are the possible messages that may be displayed: Some microinverters have stopped reporting. To me this isn't a problem right now, unless there winds up being some logic that depends on those being zero vs. not used. I See Andrew Mitchell's Enlighten Manager Mastery video for a visual walkthrough of CT troubleshooting using Enlighten Manager. meter_issue One or more meters on the system are reporting unusual Fyi: There exist 3 different Envoy-S models: I have the Envoy-S Metered Multiphase (EU) SKU: ENV-S-WM-230. The time series includes one entry for each day from the start_date to the end_date. Hopefully that data can be read from elsewhere on the Envoy, without requiring installer permissions. 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. Enphase Envoy S 'metered' Multiphase (probably identical to Envoy IQ). For the best experience on our site, be sure to turn on Javascript in your browser. The one solar panel connected to that microinverter will be out of operation C. The entire solar PV system will be out of operation B. 0000154623 00000 n metered_consumption_readingtime, How about simplifying Here is the output of envoy_reader from various Envoys. WebThe use of any other type of CT will result in incorrect power measurements, and may permanently damage the WattNode meter. I have had my solar setup for 1.5 years so far, no issue. production_readingtime (source: production.json production inverters readingTime) The CT (current transformers) are used for measuring current. @gtdiehl 0000016000 00000 n Good catch! Enphase Solar PV Installation Certification Training Flashcards WebIf 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. If production or consumption measurements received by Enlighten are negative, there could be a CT Measurement issue. 0000015247 00000 n stream I wonder if they can tweek low light efficiency for me? <> All times are GMT-5. The fix was merged into the dev branch yesterday, which usually means it will make it into the next release (2021.01.0). When this condition is detected, the response code is 500 and the response body is: Each meter interval includes the following: Returns performance statistics for the specified system as reported by microinverters installed on the system. 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. Active does not imply that the device is currently reporting, producing, or measuring energy. The Enphase Home Energy System meters solar production and home electrical loads. This would allow access to finer grained energy production data for uses such as graphing 15 minute intervals. In my situation (ct_metering_production is False) the production value is read correctly from the production/inverters section in production.json. This is called the merged time series. In addition, the response includes the attribute meter_start_date, to indicate where in the time series the meter measurements begin to be used. Could this have been fixed in a later firmware revision? 0000020597 00000 n For example, midnight on 5 May, 2015, in Pacific Daylight Time is 1430809200. Requests for times that do not fall on the 15-minute marks are rounded down. An Enphase team member may follow up with you about your feedback. WebTo enable correct operation of the Enphase Home Energy system components (including the Enphase AC Batteries), the Envoy must correctly measure the current flow across [V6Pq ]_,.7bK~lqq}e~Y4e[./7ew,X*k9IAhR4wgf e EZ%%da'6[kV^n7H"]c$)yRT@S1A| _|w,#G(@!{;?

I would like some input from @jesserizzo and others before opening a PR to merge this change. Learn what you can do if the systems meter has stopped reporting. 0000232378 00000 n By default, systems are returned in batches of 100. By providing an optional ct_enabled parameter the user can override it for testing purposes. 0000470581 00000 n There are 1609 meters in a statute mile. Examples in this document exclude the callback parameter for clarity. Automatic: When CT's are not enabled this is shown on the envoy/home page so it should be possible to automatically scrape the status of whether CT's are enabled or not. 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. Systems that are configured to report infrequently can show large deltas on all meters, especially when end_at is close to the current time. There was a reply in the Home Assistant Community forum where a person took this screenshot. Queries on system_name and reference are case-insensitive. Current Transformers (CTs) are installed to measure Solar (production) and Home Loads (consumption). I hope we can see it being updated in Home Assistant as well soon. To troubleshoot this, check CT orientation and leads, compared with voltage measurements. 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_*. 0000001916 00000 n the blue wire goes to a splice pack under the carpet under Cross your fingers, and I'm hoping it will be included in 2020.12.1. The Envoy-S Metered is a system monitoring tool, and control device. 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. metered_production_readingtime Would have to find a system that has 3Phase with Metering enabled and CTs installed. This isn't currently accessible via Home Assistant, since at least for my configuration it is polling production.json and using the `eim`` structure which never change, which is the issue being reported here. ct_enabled with default value True (requires no changes in existing client code). 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. In progress - Scheduled maintenance is currently in progress. with Envoy 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. read_at is the time at which the reading was taken, and is always less than or equal to the requested end_at. 3 0 obj The system will continue to operate normally B. I was able to check a couple things this weekend. I have had the production CT installed from the beginning and I just now got around to installing the consumption CT's. When I run envoy_reader from a command prompt, the 4 production values shown are 0. All were taken at the same time. If your application does not allow for you to include an image, you must include the text Powered by Enphase Energy. The new version of API (v4) is available at: developer-v4.enphase.com.
