Thanks for the report — I can take a look, but I’ll need logs to debug this.

Please add:

1. hm2mqtt logs (DEBUG)

   • Home Assistant → Settings → Add-ons → hm2mqtt
   • In the add-on configuration, set:
     • log_level: debug
     • debug: true
   • Restart the add-on
   • Then paste the relevant log excerpt here (around the time the problem happens)

2. Hame Relay logs (DEBUG)

   • In the Hame Relay add-on, enable debug logging (log level debug) and restart
   • Paste the relevant log excerpt here

Important: please redact/replace any IDs (deviceId/MAC, tokens, MQTT credentials, etc.) before posting.

I don’t use the hame relay add on. I used the web interface to do the mqtt settings.

But here is the debug log:

It is still not available since yesterday around 8pm

Looks like your battery just doesn't respond to any request. Try restarting the battery.

[DomeGr694]

Ok battery restart helps

Which way works better, locally or with the hame relay add on? Which one is more stable?

[tomquist]

It doesn't make a difference. It's the battery firmware that has instabilities and sometimes needs a restart.

I have a maybe similar problem with a HMA-1 (Firmware 220.12). I used it without problems for about a year in the original setup and used your ESP config to get the data into homeassistant. Now I switched to hamerelay / hm2mqtt two days ago, and suddenly some device data, especially the battery, seems to be disappearing (both in Homeassistant and in the native app). See the suddenly completely missing battery capacity in the attached screenshots.
Yesterday I managed to get the data back for a few hours by performing an hardware reset from the app, but a few hours later the battery capacity was lost again, and now the hardware reset (as well as power cycling) does no longer help.

Concerning the logs:
hamerelay logs show normal forwarding of messages, and hm2mqtt has a few connection loss warnings now and then. No errors, especially not at the relevant time.
I tried hamerelay both in mode 1 and mode 2, no difference.
Other values seem to be correct, it is mainly the battery data which is "lost". Solar inverter input seems to be correct (at least it contains changing values).
I don't know why there are some battery spikes in the original app at the time Homeassistant does not report any battery at all (at 16:00), probably it reflects the fact that some sun power on the cloudy day went into the battery after all.

I can just repeat what I mentioned above: Try restarting the battery. It's the battery firmware that has instabilities and sometimes needs a restart.
