in the vicare app i have the option to switch to “only warm water”. But in the viessmann homeassistant integration there is no mode or service to put vicare into this mode from homeassistant. Is it possible to integrate this ?
You want to have warm water, but no heating? On the device itself you turn on party mode (which turns on heating snd warm water) and turn it off immediately after (which turns off heating but let warm water on). You might want to try that.
