Is Alexa Z-Wave?

Alexa only “speaks” WiFi (and ZigBee if you have the EchoPlus). It currently doesn't support Z-Wave, the protocol of choice for home automation thanks to its high speed and low interference with other connected devices in your home.

Is Z-Wave better than Wi-Fi?

Z-Wave Has Fewer Congestion Problems As such, Z-Wave's network has much less congestion, as it operates on a lower radio frequency - 908.42 MHz. Zigbee's frequency is closer to that of Wi-Fi - 2.4ghz - meaning a lot more congestion. Jun 27, 2021
