Protocols
The "language" of your home
There are many protocols that a device can support, but mostly it's down to WiFi, Z-Wave, and ZigBee.
- WiFi is common but then depends on your network, and also consumes too much power for battery-operated devices, so usually they have to be plugged-in, which can be a hassle for devices like motion sensors.
- ZIgbee is low-power, but is a proprietary protocol, and can interfere with WiFi which can result in poor range.
- Z-Wave is probably the best choice as it’s low-power and operates on a different frequency than WiFi. Range is still not great (300ft max outside with clear line-of-site, but usually only 50ft inside, but can be as bad as 10ft through heavy walls). However, it operates as a mesh network so devices can act as repeaters which can help.
