Frequently Asked Questions

Q: Does this smart radiator thermostat work without a hub?

A: No — this thermostat uses Zigbee wireless technology, which requires a compatible Zigbee gateway hub to connect to your home Wi-Fi network and enable app and voice control. Without the hub, the thermostat can still be operated manually on the device itself.

Q: Which radiator valves is this thermostat compatible with?

A: This smart thermostat is designed for radiator valves with an M30 × 1.5 mm thread size, which is the most common standard across European and many other heating systems. Six adapters are included to ensure compatibility with a wide range of valve brands and models.

Q: How does the child lock feature work?

A: The child lock disables the physical controls on the thermostat unit, preventing accidental changes to your heating schedule or temperature settings. You can still adjust everything remotely through the Tuya or Smart Life app on your smartphone.

Q: What does frost protection mode do?

A: When frost protection is activated, the thermostat automatically maintains a set minimum temperature — typically around 5–8°C — to prevent pipes and your home from reaching dangerously cold temperatures. This is especially useful when you are away from home during winter.

Q: How long do the batteries last, and what type are required?

A: The thermostat requires three 1.5V alkaline AA batteries (not included). Thanks to the energy-efficient Zigbee communication protocol, a fresh set of batteries can last up to 10 months under normal usage conditions.
