Frequently Asked Questions

Q: Does this smart radiator thermostat work with Alexa or Google Home?

A: The TRV supports voice control via compatible smart home ecosystems. As a ZigBee 3.0 device operating at 2.4GHz, it can integrate with hubs and platforms that support ZigBee — including those compatible with Alexa and Google Home — giving you convenient hands-free control of your radiator.

Q: Do I need a hub to use the app remote access feature?

A: Yes, because this thermostat uses ZigBee 3.0 wireless protocol, a compatible ZigBee hub or gateway is required to connect the device to your home Wi-Fi network and enable full app remote access and scheduling features.

Q: Will this TRV fit my existing radiator valves?

A: The thermostat uses a standard M30×1.5mm thread, which is compatible with the vast majority of European-style radiator valves. Six adapter fittings are included in the package to extend compatibility to other common valve types.

Q: How much can I save on my heating bills with a programmable radiator thermostat?

A: By programming your heating to only run when and where it's needed — for example, reducing output in empty rooms or overnight — a smart TRV can contribute meaningfully to lower energy consumption. The app's temperature history tracking helps you identify further opportunities to optimise your schedules over time.
