How can I set the phases of a wallbox in the Home Assistant via the website?

Hi guys,

I have a Vestel evc04 wallbox and I use evcc to charge my electric vehicle. My wallbox does not allow me to set the phases via Modbus TCP.

Therefore, I thought that it must be possible to read the wallbox’s website via Scrape or similar and switch between 1P and 3P with an automation depending on the excess solar power.

So I would like to mark id=“currentLimiterOnePhase” value=“0” or id=“currentLimiterThreePhase” value=“1” with selected=“selected” depending on the excess solar power and save it.

How can I do this?
