Do you need to control the temperature remotely, or just switch it on? If the latter, could you just leave the existing potentiometer / power switch always in the on position and add a new zigbee relay to cut power to the whole works on & off?

This personal inventory project hasn’t been updated in a couple years, but looks Ike it could work for what you’re describing.
The best example that comes to mind is Ardour, a FOSS digital audio workstation that charges for binaries. Their FAQ says
It’s a bit mixed in with the “pay for support” model, since you’re basically on your own if you build it yourself. Which probably makes support a lot easier, since there are fewer supported configurations. This seems like a pretty workable model for something as complex as Ardour, but idk how well it would work for simpler projects.
think it also helps that Ardor is used directly by individual users, and its proprietary competitors are often quite expensive. If you’re making something that already has a lot of “free as in beer” competition, this may be harder to pull off.
