Use a shelly and the shelly plug-in. You'll also need a way to get environment.inside.temperature into SK. I used Ruuvi Tags for that. Works great.
Then, you'd only need to have some logic somewhere to activate the shelly, which would in turn fire the heater. Node-Red would be great at this.
I had intended to do this on my old boat, but life changed and I had to sell it. In the market now for a replacement and will be doing this exact thing on the next one.
