Smart Radiator Thermostats

Buy smart WiFi radiator valves

With smart radiator valves (thermostatic radiator valves), you control the temperature per room instead of “one setting for the whole house.” That’s where the real difference is: keep the living room comfortable when you’re there, heat your office during working hours, and keep bedrooms cooler at night. This zone-based approach doesn’t just improve comfort—it also helps prevent heating empty rooms unnecessarily. It’s one of the most effective smart home upgrades if you want smarter heating without replacing your entire system.

How does a smart radiator valve work in practice?

A smart radiator valve replaces the existing knob on your radiator valve body and automatically manages heat output. You set a target temperature (manually or via schedules), and the valve adjusts the radiator accordingly. Many models include practical features that make a real day-to-day difference, such as weekly programs and open-window detection: when the valve detects (likely) ventilation, it can automatically reduce heating so you don’t “heat the outdoors.”

Zigbee 3.0 and a gateway: a stable foundation for expansion

In this category you’ll often find solutions based on Zigbee 3.0. In practice, that usually means using a Zigbee gateway as a central hub. The advantage is scalability: start with one or two radiators and expand easily later, while managing everything in one app. Gateways also make it easier to use voice control and automations within your ecosystem.

Key specs to look for (that truly matter in real use)

1) Mounting & compatibility with your radiator

Check which connection type you need. Many smart radiator valves are designed for common sizes (for example M30x1.5) and come with adapters, so you can install them on most radiators without hassle.

2) Power and maintenance

Many radiator valves run on AA batteries. That keeps installation flexible (no wiring) and makes battery replacement simple when needed.

3) Display, manual control and schedules

An LCD display and manual controls on the valve are useful for quick adjustments, but the biggest gains come from schedules: fixed temperatures at fixed times, matched to your daily routine. That’s how “smart heating” becomes automatic.

4) App, platform and voice control

Check compatibility with your setup (for example Tuya) and voice assistants (such as Google/Alexa), so your radiator valves work seamlessly with the rest of your Smart Home.

Which version should you choose: vertical, horizontal, or a complete set?

The best choice mainly depends on your radiator layout and how you want to start:

• Vertical or horizontal: useful when space around the valve is limited, or when you want the valve to align more neatly with your pipework.
• Complete set including gateway: ideal if you don’t have a Zigbee hub yet and want to start controlling rooms right away.
• Standalone gateway: smart if you already have valves (or if you plan to add more valves/switches/sensors later) and want to build one central system.

Combine smart devices for maximum results

For the best setup, combine smart radiator valves with a central foundation such as smart thermostats and build from Smart climate control. For even better decision-making, add insights with measurements and routines (for example by monitoring comfort and humidity values) via temperature & humidity sensors. Prefer a data-driven approach? Then smart energy monitoring is a logical next step to make usage visible and actionable.

Start room-by-room heating control today

Whether you want to start small with one radiator or install a complete set right away: smart radiator valves give you immediate comfort and control. Choose the right form factor (vertical/horizontal), ensure a stable Zigbee foundation with a gateway where needed, and build step by step toward a Smart Home that automatically adapts to your day.
