Most of model infrared universal remote devices from Broadlink isn’t support HomeKit officially. Thanks for plugin “Homebridge Broadlink RM Pro” ( https://github.com/kiwi-cam/homebridge-broadlink-rm#readme ) which still supports low-end model such as RM3 mini. It is easy to find from Amazon store.

Reason make implement of low cost model RM3 mini instead of other high-end model:

• Just use for remote air conditioner cause this kind of home appliance isn’t easy to make a replacement
• Purchase an air conditioner that supported HomeKit directly for future

1 Use Broadlink app to config RM3 mini join into your wifi network.

2 Just login to homebridge admin and go to page “Plugins”, then search “Broadlink” and install plugin.
