Tuya Zigbee Indoor Siren with Temperature & Humidity

A Zigbee 3.0 indoor siren that doubles as a temperature and humidity sensor — useful on its own, and genuinely powerful when paired with motion sensors, door contacts, or a smoke alarm. The built-in 90 dB sounder is loud enough to be heard across most UK homes.

Volume, melody, and duration are all configurable from your hub. Works locally — no cloud needed once paired. One of the most widely-reviewed Zigbee sirens in the Home Assistant community.
