[BUG] sensor data are unavailable most of the time since latest update

[holli73]

Describe the bug
since i upgraded to the latest version and i used re-configure to switch between enlighten and entrez makes no difference it is getting worse every hour - only if i reload than it works for few minutes and stops again

Account type

• [ x] Installer
• [ x] DIY / DHZ
• [ x] Home Owner (This integration is not (fully) functional with a home owner account!)

Envoy

• [ x] Metered with CTs installed

• Metered without CTs

• Standard

• FW version: D8.3.5528

• Amount of micro inverters connected: 82

Home Assistant

• Version: 2026.5

Additional context
this is the power production value for the last 30 days

and here are f.ex. die last 12 hours

so you can see i hardly get values...

i did make sure that my enphase/network has no issue so i added -> https://github.com/vk2him/Enphase-Envoy-mqtt-json <- and this reports every second live values to ha without a single drop

so there must be something broken with the latest version - maybe it is related that i do have 2 envoy's in my network - i have one with ct's and 82 invertes connected and one envoy with only 2 inverters and no ct's

It seems the resolution on the values increased at some point and now it cannot keep up. Did you decrease the time between sensor updates? You can also try to increase the timeout value for getting data. Or turn on "realtime updates".

[holli73]

i did not change config values - i use 60 min. refresh and 120 for timeout and real time is enabled with 60 - so no config changes...
i use the devstatus endpoint as well - is there any tracing/debugging log i can enable to see what is causing this?

i use now the mqtt provided data and make my needed calculation through my own created template sensors - as only initially will work and after 60 seconds all get unavailable again

@holli73 Please enable debug logging for the integration, leave it running for a few minutes and send me the logs at ziener06joduur@icloud.com

@vincentwolsink I think I have the same issue. It gives: Failed setup, will retry: Error communicating with API: All connection attempts failed, but it fixes (and breaks) automatically a few times per day. I have the standard envoy (not metered). I've sent my HA debug log by email to you.

@vincentwolsink any idea what I can do to fix this? The problem still persists.

@vincentwolsink even after updating home assistant core and the integration, the problem still persists.
