I have a Green Mountain pellet smoker and it has a wifi enabled controller on it.

I know it’s not the same thing as your pellet stove but it has all the same elements. They just do a different process.

Maybe you could copy parts of its functionality into your own design.

At least, it could inspire your design.

I use a 50/50 mix of isopropyl alcohol and white vinegar. I drip about ten drops in one ear, let it sit there while I read a book on my side. Then I catch it all with a Kleenex tissue as I rotate my head.

This works great on ear infections too.
