Shelly
BLU H&T
A compact battery-powered Bluetooth temperature and humidity sensor with a CR2032 cell and roughly three-year battery life. Sold in Bluetooth and Bluetooth+Zigbee (ZB) variants, both splash and dust-resistant for kitchens, bathrooms, and basements.
Local over Bluetooth/BTHome, optionally relayed by a Shelly BLU Gateway to the shelly integration; the BLU H&T ZB variant also joins a Zigbee network (ZHA or Zigbee2MQTT) via a Zigbee coordinator. Battery-powered (CR2032, ~3 year life), splash and dust-resistant (IP54 on the ZB model), with a push button for on-demand readings.
