Does anyone know if one of the MQTT Topics on the VenusGX reflects the charging state/algorithm currently in use? Maybe its hidden behind a specific number, tried all of them but could not see one. Thanks a lot Norbert

VenusGX MQTT Topic reflecting Charging State (Bulk, Absorption,Discharging)...
Hi Norbert,
Yes it does. If you can use SSH to connect remotely to the GX, there is a command line tool available called 'dbus-spy'. This is a good starting place to discover all the dbus messages and locations and device instance IDs. For the VE direct model of MPPTs (100/30 etc) the state can be read at:
N/xxxxxxxxxxxx/solarcharger/nnn/State
Replace xxxxxxxxxxxx with your VRM portal and replace nnn with your device instance ID.
0 - Off
2 - Fault
3 - Bulk
4 - Absorption
5 - Float
6 - Storage
7 - Equalize
252 - ESS
I'm sure its similar for other inverters/MPPTs. If you subscribe to the topic N/# and log the results, it just a matter of filtering through them to narrow down the results.
Regards,
Damon
