The Fumis integration connects your pellet stove to Home Assistant through the Fumis online service. Fumis, by ATech Electronics in Slovenia, makes the combustion controllers found in pellet stoves from many different manufacturers. The Fumis WiRCU Wi-Fi module connects your stove to the internet, making it possible to monitor and control your stove from anywhere.

Limitations from the docs

The integration communicates with your stove through the Fumis online service. Both your Home Assistant instance and your stove's WiRCU module need an active internet connection. If either loses connectivity, the integration cannot communicate with your stove.
After sending a command to your stove, such as changing the target temperature or turning it on, it can take up to a few minutes for the change to take effect. The command travels from Home Assistant to the Fumis online service and then to your stove on the next update cycle.
