Errors in log for Marstek Venus E 3.0 using hame-relay & hm2mqtt

[gbonny]

I'm using Tom Quists hame-relay and hm2mqtt ( https://github.com/tomquist/) in combination with Mosquitto and my Marstek Venus E 3.0 home battery.
Domoticz discovers a lot of devices. However I get a multiple errors in the logging every minute:

There are corresponding entities:
MQTT <MAC>_recharge_mode 1 HAME Energy VNSE3-0 <MAC> (Recharge Mode) General Text threePhase
MQTT <MAC>_version_set 1 HAME Energy VNSE3-0 <MAC> (Version Set) Light/Switch Switch 800W Version
MQTT <MAC>_working_mode 1 HAME Energy VNSE3-0 <MAC> (Working Mode) Light/Switch Switch Automatic

Does this require some programming on Domoticz or hm2mqtt/hame-relay side? Or can this be surpressed by either one?

Using Domoticz 2026.2.

Seems the MQTT Discovery config topic on the hm2mqtt side is not correct. It is missing some options to define the STATE.

OK, I filed an issue here: https://github.com/tomquist/hm2mqtt/issues/360 lets see.

Got a reply from Tom Q:

This is a Domoticz bug, not a config issue on hm2mqtt's side.

hm2mqtt publishes a valid Home Assistant MQTT select config: the state carries a raw value (threePhase) and a value_template maps it to the option label (Three Phase). Home Assistant applies that template and matches fine. Domoticz doesn't — it compares the raw value against the option list and errors.

Please report this to Domoticz. Summary for them:

In hardware/MQTTAutoDiscover.cpp, CleanValueTemplate() strips the select value_template's {% if %}/{% set %} mapping, so handle_auto_discovery_select() compares the raw value against select_options and never matches. Domoticz already has parseMapTemplate() (used for climate action_template) that could be applied to select value_template to fix this.

@Gizmocuz, can you fix this?
