issue with envoy meter measurements issue with envoy meter measurements
If your system has stopped reporting data, youll see a problem message like this: Learn what you can do if your system stops reporting data. Reported values while metering disabled: Note: If a system does not include a given device type, that key is left out of the returned hash. I Valid values for datetime_format are iso8601 and epoch. You can sign up to be notified by email if your system experiences either type of production issue. 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. In other words, without CTs to use the Envoy's accumulation of WH Today and WH Past 7 days, you'd need to be able to get Envoy Reader to poll /api/v1/production. WebEnlighten declares a Meter Issue system status when it detects a possible problem with the CT or storage measurements. Webmeter There is a communication problem between an Envoy and a revenue-grade meter on the system. By default, systems are returned in batches of 100. returns systems that currently have production issues. I have a 3 phase power system, so I also have 3 CT's which each measure 1 fase, but in the Ephase app the value is shown as a single Power consumption parameter. 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. If the system doesnt have any consumption meters installed, the response includes an empty intervals array. I will make a capture tomorrow when it's light and the system is actualually producing. 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. Have an assistant crank the engine for a few seconds while you watch the meter's readout. I am quite sure my problem is based in the start-up voltage and minimum voltage. All rights reserved. If you do not want to accept all content types, specify JSON only: Endpoints that receive dates expect the format YYYY-mm-dd. There is an issue with the meter measurements. If a request is rejected because one of these limits has been exceeded, the response includes information about why the request was rejected: period tells you how long to wait. Currently to minimize api calls between the envoy and home assistant one function is called to gather up all the data (even if the device does not support the parameter) and send it across. )bJ60F-phEZ Though this time I had someone add my PR to the list of PRs that should be included in 2020.12.1. OUTBACK SEALED GRID-TIE INTERACTIVE INVERTERS, Skip to the beginning of the images gallery, Contact us for availability, pricing and freight quote, Contractor and commercial discounts available, Specials and multi-pallet/container discounts, Complete residential and commercial grid-tie Solar kits, Design assistance, Permit submittals, Schematics, Enphase Monitoring CT Getting Started Guide, Enphase Consumption Monitoring CT-200-Split Installation Guide, Enphase Ensemble Technology System Planning Tech Brief, Envoy requires 2 CTs to connect to terminal block. 0000017403 00000 n The Envoy can accept 2 x CTs paralleled into the same CT terminal. 0000155287 00000 n An explanation for the difference may be rounding errors or different time of measurement. So to make changes unfortunately we can't add a new sensor and display the new data. (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.). The CT direction arrow of each CT, in a Net metering (load with solar) configuration, will always face towards the load circuits of the site. Last one. If the first request does not return a full list, use the next attribute in the response body to request the next page of systems. 0000078062 00000 n I discovered that /production.json can also provide per-phase values. The CT (current transformers) are used for measuring current. All API requests, regardless of version, are throttled according to the limits of the application plan you chose when signing up for an account. Returns consumption as measured by the consumption meter installed on the specified system. Envoy reader makes an assumption depending on the type of Envoy whether CT metering is being used. @gtdiehl - I think the only cases where you'd want to use /api/v1/production are: I don't have code changes that are worth submitting. It is important to understand these differences when installing Envoy CTs. 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 have read through everything yet but I want to point out that when polling uses the /api/v1/production page the envoy appears to only update it every 15mins. @rct I get what you're saying. Please refer to the Enphase technical system wiring examples for further clarification of correct CT placement across the electrical cabling of the site. When the production version of envoy_reader will be updated, will this get automatically updated in existing Home Assistant (Enphase Envoy add-in) installations? Better ($) electric cars are using heat pumps more effectively to heat. 0000470581 00000 n Meters that have been retired from a system will show an end_at that doesnt change, and that eventually is far away from the current time. I wonder if that is why your blue bars are labeled production but look like they follow a consumption pattern? I would have to look into how to send specific data from the envoy_reader API to Home Assistant. I am just grasping at straws here. Envoy-S Metered and Envoy-S Metered Multiphase (IQ Envoy) are both black but the Envoy-S Metered Multiphase has the cover screw on the right side while the Envoy-S Metered has the cover screw on the left side (like Envoy-S Standard). However, each request must include them both. A. Recently my meter box was moved and the sparkie put the consumption CT backwards. metered_consumption wNow: 0.836 (gets truncated to 0). All times are GMT-5. CXg*@UDXWkV+-40VwdD$pq l/c=_"8-h.iwF3u;md0I%02XrUy.UZj-CRU Shr{|+r?`vQbqp`ZktIxp16De#~`hze2]@k&}Y"U3F0VKB5tkU)7^9{'?epa #C#fIp];efXilt(cz#4STR42I ,~g^*N*9cU+!d`*,2'd!_]G?n*W& >4. Here is heavy overcast at the end of the day with sun low and far to the side of the array. For more details, visit 0000452724 00000 n My Envoy IQ is running D5.0.49 (77afa8) Build date Thu Mar 19, 2020 01:44 AM PDT. When I investigate the raw numbers from interrogating the envoy direcly it actually shows me the low power factor. The sensor should produce a voltage pulsing signal. I see now that there was mention of these URLs in the Envoy-S data scraping blog that I missed previously. Or maybe the Envoy combines the data of all three phases and the differentiation gets lost? Hopefully that data can be read from elsewhere on the Envoy, without requiring installer permissions. privacy statement. It appears that this value is probably taken from the same L1 input, but its value differs few-thousand's of a volt. 0000015247 00000 n 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. Yeah hopefully it'll make it into the 0.119 release! For example, there are 100 centimeters in a meter. &pLlV y*Hv. If the message persists and is not due to unusual production or consumption conditions, contact your installer for help. I have an Enphase system but it only has production and the blue bars are in the same orientation as in your chart. If your system has AC Batteries: Some batteries havent charged or discharged recently. 0000004049 00000 n Observation: metered values get truncated instead of rounded. I would also prefer if the timestamp of when the values were updated can be added, e.g. /production.json: "type": "eim", "rmsVoltage": 245.583 0000063893 00000 n Completed - The scheduled maintenance has been completed. Attributes that are dates are named accordingly (e.g., summary_date, start_date, end_date). Regarding measurements for each phase, he Envoy has a URL that deliveries a stream of measurements -. (*) Note: I don't know that production[0].type is always inverters and production[1].type is always eim. WebAN_6612_032 Energy Measurement in Split Phase Systems Using 78M6612 Rev. There was a reply in the Home Assistant Community forum where a person took this screenshot. All requests support an optional callback parameter. Are all three phases wired to your Envoy power connector_(most-left connector on the Envoy)_? So I swapped the leads on the Envoy for the consumption CT's and have been monitoring all day and the data looks good. The code is currently returning values for those rather than your 'not available' message. 0000012600 00000 n The next screenshot shows the cumulative effect of the negative reading on the lifetime measurements; Screen Shot 2019-01-04 at 10.24.51 PM.png, Solar Panels for your Home, Grid Tied Solar PV, Screen Shot 2019-01-04 at 10.24.59 PM.png, Screen Shot 2019-01-04 at 10.22.19 PM.png, Screen Shot 2019-01-04 at 10.26.09 PM.png, Screen Shot 2019-01-04 at 11.25.06 PM.png, https://enphase.com/sites/default/finvoy-EN-US.pdf, https://thecomputerperson.wordpress.com/2018/08/18/what-is-inside-the-enphase-envoy-s-teardown/, https://www.solarpaneltalk.com/filed7&d=1546658760. Returns a time series of energy produced on the system over its lifetime. 0000232417 00000 n If the system doesnt have any revenue-grade meters installed, the response includes an empty intervals array. Enphase Ensemble Systems. Immediately to the left of or above the mark, you must display the words Powered by in a clear and conspicuous manner and in a minimum eight-point font. https://github.com/dlmcpaul/EnphaseCollector. An Enphase team member may follow up with you about your feedback. I use Envoy S but without any CT's installed. There is a limit to the number of systems that can be returned at one time. 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. About the Enphase Envoy-S Metered The Enphase Envoy-S Metered communications gateway enables performance monitoring and remote software and firmware updates of an Enphase Microinverter System. For example, P0500 (VSS circuit malfunction) is the most popular code This "readingTime" is probably accurate enough to be used as timestamp for data in /api/v1/production. My envoy has values for those rather than all zero, because metering was turned on a while but wasn't giving the right values. Solar Production CT MUST measure all solar circuits on site. The text was updated successfully, but these errors were encountered: @lnlp Would it be possible for you to post a copy of your /production.json? Right after connecting the power lines to the grid I already have some statistics of the grid meter (in the Netherlands called the Slimme meter, which you can read through the P1-port using i.e. 0000018303 00000 n In that case, where is the total power reported in /production.json ? In 'case A' one may wonder why the phase voltages are reported separately for production, net-consumption and total-consumption. All dates are in the timezone of the requested system. So far, I haven't seen a flag from the Envoy API that indicates whether it is using the inverter measurements or the CTs, but maybe I haven't looked deeply enough. WebIf your meter has a milliamp scale, use it whenever possible because its a more sensitive scale. If you see a green checkmark, then your system is fine with normal system production. Copyright 2014 SolarReviews All rights reserved. 0000003706 00000 n The production or consumption measurements received by Enlighten are negative. period_start and period_end tell you when the minute (in this case) started and when it will end.

(*) Note: I don't know that production[0].type is always inverters and production[1].type is always eim. Intervals are listed by their end dates; therefore, the first interval returned is 5 minutes after the requested start date. If you are installing in a multiphase application, the power line communication signal must be coupled My blue bars show production and yours appear to show consumption. 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 0000033107 00000 n 0000268009 00000 n Intervals are listed by their end dates; therefore, the first interval returned is 15 minutes after the requested start date.
