Everything you need to connect your Fujitsu air conditioner to your smart home.
Local control
Control your air conditioner directly over your local network, without relying on cloud services.
Two-way communication
Two-way communication between the air conditioner and the dongle provides accurate real-time status. Unlike an IR bridge, faircon knows what is actually happening with your air conditioner.
Instant response
Commands are sent directly over the local network, providing fast and responsive control.
Works alongside existing controls
faircon does not interfere with IR remotes or wall controllers. They can be used at the same time. Changes made using an IR remote or wall controller are also reported to Home Assistant through faircon.
MQTT & autodiscovery
MQTT provides flexible integration with Home Assistant and other home automation systems. Home Assistant automatically discovers and configures the device.
Home Assistant
Integrate your air conditioner with Home Assistant and control it alongside the rest of your smart home.
Wi-Fi
Connect your compatible Fujitsu air conditioner to your home Wi-Fi network and control it from your local network.

faircon is based on an open-source project, with the source code publicly available on GitHub.
