How to set target temperature for Sensibo thermostat in automation

I am trying to have an automation set the target heat for the Sensibo Thermostat device and none of the actions are for actually setting the heat. While I am new to Home Assistant I have been doing home automation for 8 years now (and have a background in IoT). This should be obvious and intuitive and yet it is not. Sigh…

Any help would greatly be appreciated.
