Shelly Wave H&T

Quick verdict

The Wave H&T is the Z-Wave sibling to Shelly's Wi-Fi 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 Wi-Fi version if you are committed to a Z-Wave network and do not need the display.

Standout: Battery-powered Z-Wave temperature and humidity sensor with full local control via Z-Wave JS.
