This community has gotten me excited about integrating all of my devices into SmartThings. I couldn’t find any examples for the Central Boiler Wood Furnace Firestar Controller so I made one:
Just a prototype at this point but it displays the water and fire temperature. I’ll add the furnace state and status messages next. Contributing this as I would have wanted such code if I could find it.
So this is for the Firestar II controller I take it?
Yes. It talks to the little webserver that runs on the controller.
I see, unfortunately I have a Maxim M250 with the Firestar gen 1 controller. It has no web server, and cannot be swapped out for a Firestar II. 
I will have to crack it open and harvest the information via sensors.
Have you interfaced with Alexa at all? I was hoping to be able to ask Alexa for a stove status and then get a mode/water temp/firebox temp reply.
Any updates? I got a new CB for Christmas.
