Yes. Next to ‘smart’ devices, Homey supports regular wireless devices like set-top boxes, ‘dumb’ TVs, socket switches and air-conditioning.
Unfortunately, Homey does not do magic, so devices do need a wireless control method. For devices without wireless controls, like your trusted coffee machine or regular lights, workarounds are available.
Add, for instance, a relatively cheap socket switch to these devices and include them in your Homey ecosystem without having to buy a completely new device!
