According to Homey (where I have ordered a bridge) the bridge has all the following protocols built in.
Wifi, Zigbee, Bluetooth, Z-wave, 433MHz, IR
However, all threads about the bridge/433MHz seem to end up in disappointment where the user cannot utilize any 433-devices. Is it so that the App is just not yet prepared for 433MHz or is it so that the advertisement is crazily misleading?
