If anyone is wondering, that glass diode package is called a MELF. I don’t know why.
They suck because they roll off the PCB during the pick and place process due to low surface area contacting with the solder paste.
I’ve had to replace so many of them.
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.
Hahaha!!! You are soooo very right!!!
