Recommended thermometers

An externalized temperature measurement device, placed where you live, is essential in a VTherm setup: it ensures reliable, comfortable and stable temperature control.

The following temperature sensors are commonly used with Versatile Thermostat and are fully compatible with Home Assistant:

• ⭐ Sonoff SNZB-02D Zigbee — the most used and therefore the best choice,
• Neo NAS-TH07B3 Tuya Zigbee,
• Moes ZSS-KB-TH-LF-C Tuya Zigbee,
• Sonoff SNZB-02P Zigbee,
• Aqara T1 Zigbee,
• Netatmo Weather Station (cloud integration).

Configure the room temperature sensor in the VTherm main attributes (see base attributes).

Reporting interval

VTherm needs regular temperature updates. If the sensor does not report for too long, the VTherm goes into safety mode.

• Many Zigbee sensors (Aqara for example) only report when the temperature changes. In a stable room, the delay between two updates can exceed the safety delay: adjust the reporting settings in Zigbee2MQTT if possible.
• Cloud sensors like the Netatmo Weather Station are only updated every few minutes.
