What is it?

It is an electronic board that allows you to easily control via MQTT many pellet stoves equipped with a mainboard manufactured by Micronova. To my knowledge it should be compatible with the boards listed on Micronova website (as of 2021/09). I cannot guarantee any compatibility, but the associated firmware is Open Source and easy to adapt if needed.

Disclaimer

What I sell is an electronic circuit and not a program. The one compatible with this circuit is free and open source software. It is based on a personal hobby project. When looking for information, I've met people who have shown interest for such board… hence this product on Tindie! I cannot test the design beyond my own stoves. The board is the one specified on GitHub (open design). The board is tested before shipment. The firmware is on GitHub, but I cannot guarantee it is bug free (feel free to add an issue on Github!). In other words, I send a board that is "working" without any further warranty.

Main features

This control card allows you to:

• turn on and off your heater
• read the detailed status of the heater
• read the flame power (0-5)
• obtain the temperature of the smoke
• obtain the room temperature
• obtain the water temperature (if hydro model)
• get the water pressure (if hydro model)

Why did I make it?

I make this because I myself have 2 stoves equipped with MicroNova mainboard, as it wasn't that easy to set up, I decided to share it to let as many people as possible benefit from it.

What makes it special?

This circuit is compatible with at least 32 different brands of stoves, which means that hundreds of pellet heater models are compatible without having to rewrite the program.
