SONOFF TH Elite THR320D - Smart temperature and humidity monitoring switch, White

The SONOFF TH Elite Smart Temperature and Humidity Monitoring Switch THR320D is a Wi-Fi switch for monitoring environmental conditions and automating compatible equipment. Its built-in LCD displays temperature and humidity readings, and a single 20 A dry-contact relay switches a connected load on or off. The eWeLink mobile app supports remote monitoring and control, and voice control is available through Amazon Alexa and Google Assistant. Temperature, humidity, or programmed times can be used to trigger automation. The relay has a maximum switching rating of 240 V AC / 20 A.

The switch is AC mains-powered and accepts an input voltage of 100–240 V AC. Its white PC V0 housing is intended for indoor use, and physical controls on the unit provide a local operating option. Supported applications include heating and HVAC equipment, boilers, greenhouses, and pool heaters, provided the connected load is within the relay rating. This is an on/off monitoring switch rather than a lighting dimmer. Automations can use the sensor readings as well as programmed schedules.

Key Features:

• 2.4 GHz Wi-Fi supports connection to a wireless network for app-based monitoring and control.
• Up to eight smart schedules, including weekly schedules, allow timed operation.
• LCD readings update approximately every five seconds for near-real-time temperature and humidity information.
• Historical temperature and humidity data can be stored for up to six months and exported in XLSX format.
• IP20 protection rating identifies the unit's enclosure protection classification.
