ZWE operating mode with photovoltaic surplus

[TechSaiyajin]

Hello,

I would like to activate the heating rod (ZWE1) when there is a photovoltaic surplus.

Is there a way to switch between automatic and ZWE operating mode via automation?

I think this should work: For heating: Set climate.luxtronik*_heating

• .state = heat (hvac_mode) and
• .preset_mode = boost and
• .temperature > (.current_temperature + number.luxtronik*_heating_hysteresis)

For Domestic Water Set water_heater.luxtronik*_domestic_water

• .state = electric (operation_mode) and
• .temperature > (.current_temperature + number.luxtronik*_dhw_hysteresis)

Perhaps you have to play around with the ZWE config values:

• number.luxtronik*_release_second_heat_generator
• number.luxtronik*_release_time_second_heat_generator

That works, thank you very much!
