Shelly Wave H&T

Quick verdict

The Wave H&T is the Z-Wave sibling to Shelly's WiFi H&T. It reports temperature and humidity over your Z-Wave mesh, fully local through Z-Wave JS, with the long battery life and reliable range Z-Wave sensors are known for. Pick it over the WiFi version if you are committed to a Z-Wave network and do not need the display.
