# Fumis

> Fumis is a built-in integration for Home Assistant. It has 47 installs sharing analytics and needs the vendor's cloud.

Fumis is a built-in integration that connects pellet stoves with a Fumis WiRCU Wi-Fi module to Home Assistant. It talks to the vendor's cloud, so the stove needs that connection to be controlled. It adds a climate entity along with sensors for fuel level, fuel consumed, burning time, igniter starts, misfires, fan speeds, the combustion chamber, alerts and errors. Number controls cover fan speed and power level, switches cover eco mode and the timer, and a button syncs the stove clock. Home Assistant can discover the stove on the network and offer to add it, and setup is done in the UI using the MAC address and PIN code from the module label. Connection settings can be changed later without removing the entry, and a diagnostics file can be downloaded for bug reports.
