Could you change the temperature inside the Vaillant app?

Than you also could use service water_heater.set_temperature. Give it the entity of your water-heater and the desired set point. I use this to change the setpoint during the day to heat up when sun is shining.

This has worked for me for some time, I had setup an automation to heat my water to a higher temp when my solar panels have overproduction. Also made an automation to have the temp set to 60 for a few hours instead of the legionella program as 70 degrees celsius is not needed with regular use. But for some time now I get an error:

aiohttp.client_exceptions.ClientResponseError: 401, message='Unauthorized', url='https://api.vaillant-group.com/service-connected-control/end-user-app-api/v1/systems/c6c70696-22da-4dba-96b0-f04f6182aaab/tli/domestic-hot-water/255/temperature'

Has anything changed here? I could not find it as issue.
