PV data no longer arriving in Home Assistant

[mrfixit1]

Sometime today PV data stopped arriving in HA. Somehow my Growatt datalogger had lost its rerouting settings. Restoring them (i.e. ResolvDomain to OFF and Server IP = HA LAN IP) only worked for a few minutes, after which they regressed back to the defaults. I eventually fixed this with a hard reboot of the datalogger and another restore, after which the settings appear to be persistent again.

However I’m still not seeing any PV data in HA. I tried restarting the grott add-on, the sequence in #27 (comment), reloading HA, rebooting HA, reinstalling grott and trying the beta version, all without success. After every restart of the grott add-on, the log ends at:
Hostname : 8ce4abae-grott
IP : 172.30.33.3 , port : 5279

Very similar to #32 and #27, but so far without a workaround. Ideas welcome!

Config: Grott stable branch (2.8) v0.1.10, HA core 2024.7.2, Supervisor 2024.06.2, HAOS 12.4 on a Pi3.

I have the same problem. Also from today.

Hi, It seems to come from growatt forcing a reset of the sticks to the default configuration if it is not using the new server IP.

A temporary workaround is to update the growatt server IP in the configuration. You can find the procedure here: egguy/addon-grott-beta#51 (comment)

Thanks for the quick reply and tip Etienne, the workaround worked for me. I’m closing this issue as the fix will be handled by johanmeijer/grott#565.
