I'm no sure you can trigger automation from temperature changes as you want. Rest of automation should be doable with shortcuts but that first part is problematic. I might be wrong so wait what more experienced are saying. Only thing I could think of is use of dummy switch that works on schedule. https://github.com/kbrashears5/typescript-homebridge-schedule This way you can make switch that turns on/off at set interval and use it to kickstart your automation.
