How to enable vacation mode on thermostats (homematic)

I replaced all manual thermostats in my house with the homematic ip devices. Now I’m able to change temperature with Homeassistant. Next step is to create some fancy automations like turning off heating when leaving home or turning back to default auto mode when back home.

But how can I trigger the vacation mode? I don’t want to manually set every temperature for every room since I also have a time based automation set up in the CCU.

If your using nodered there is a pallet (i can’t remember what they call add-ons) thermostat ramp, been looking at using that as a base temperature and then sending an increase of I want extra heat.
