I was able to get both my Envoy-R and IQ Envoy (combiner 4) working with Brian Campbell’s integration at GitHub - briancmpbll/home_assistant_custom_envoy .
However, the total daily production in HomeAssistant from the IQ Envoy does not add up to the total in Enlighten. It’s sometimes off by as much as 1 kWh a day. I investigated this and saw that the IQ Envoy current production sensor went offline, sometimes for long periods .
For example, this morning, it happened for about 15 minutes.
All the other sensors for that IQ Envoy also go down during this time.
I know the IQ Envoy device itself did not go down and was pingable on my network, due to running Smokeping on that device. Here is the data for the time period .
So, it looks like there are still issues with the integration getting the data from the IQ Envoy.
The same problem does not happen with the data from my Envoy-R (LCD). The production data for that device is an exact match with what’s displayed on its HTML page, which is rounded to 1 decimal, but still not an exact match with Enlighten (rounded to 2 decimals).
