Just the PCB: Base price, just the PCB
Kit 1: Includes the PCB and the necessary optocouplers and resistors
D1 Mini: Adds a WeMoS D1 Mini (not pre-programmed, as there are specific modifications to be made in the program)
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.
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 Lectronz! 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.
This control card allows you to:
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.
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.

All the project details for the firmware are available here.
Dimensions: 67.9 mm* 45.48 mm.
Power consumption: max 400mA at 3.3V.
I mainly send items by standard post via the national postal service.
For certain countries, delivery to a collection point (Mondial Relay / InPost) is available and is therefore recommended (as it offers accurate tracking and insured parcels).
I post the parcels when I have time, usually at the end of the week. Delivery then takes just under a week.
