Hello,
I was wondering. Are there any project that made an successful integration with the esphome Micronova integration and there pellet stove?
Thanks.
Yes, at the very least the person who developed the component did. Do you have a real question?
I like to know if anybody besides the developer else use this component successfully and how well it works and which hardware they use to make it work.
I was thinking to make a PCB board for this. But first I like to know how well this software solution works.
Hi,
If anyone is still watching this thread I have a question.
I’m building micronova controller based on philibertc project.
I see two ways to proceed - use project’s own firmware and tie it with mqtt to HA or use ESPHome.
However it’s not yet clear how do I control stove “room temperature” if it is possble at all and maybe the only useful feautures of it is to switch on/off and see stove status and I still have to add thermostat (esphome controlled relay with remote temp sensor at the room).
Would anyone advise?
You want control room temperature without temperature sensor? Stove temp sensor is controllable.I control stove power with external temp sensor,no need extra relay or another esp.Sorry for my english.
My stove is located in another building, so external ntc probe is problematic. I can’t get it to work - stove does not seem to react to external thermostat either I connect a relay or fixed ntc probe (10k). All options I can set with esphome micronova component also seem to have no effect except for on/off switch. My stove uses L023-7 micronova board and is made by MCZ (red compact 24).
Maybe i dont understand your problem exactly,but you no need wired sensor.I have shelly blu sensor in esphome(micronova esp node),made another thermostat and it controls power of stove.works nicely

Thank you for the info. I see how it’s done. Not sure my stove responds properly to it’s “power” number - it’s acting a bit wierd.
However, I finally found that it does respond to it’s external thermostat contacts. I was confised when tesed it with multimeter as it shows short-circuit even without relay connected. It was my mistake.
So simple dry contact relay works ok with my stove, so I can use any simple thermostat or, in my situation, esphome with relay.
