Thermostats, radiator valves and air monitors that talk to the hub in your house. The plan lives on the hub, so the heating keeps to it with the internet down.
Every one talks to the hub in your house. No maker's cloud, nothing a month.
What they do on the hub
Joined once. Then part of the house.Joinedonce. Thenpartofthehouse.
Room by room
Each room with a thermostat or a radiator valve holds its own temperature: living room 21°, bedroom 18°.
A plan the hub keeps
Home 21°, Away 16°, Sleep 18° and Boost 24°, on a schedule kept on the hub, not on a phone.
Turn it up, it stays up
Turn the dial on the wall or in the app and the house holds it until the next change, and says who set it.
Fresh air, in colour
CO₂ shown green, amber or red, with a nudge to open a window.

Which models, and what each brand does once it has joined. Not sure about yours? Send us a photo and we will tell you straight.
Bosch
Works locally
Room Thermostat II 230V, the Zigbee version, wired to switch the boiler.
The Room Thermostat II switches the boiler itself and joins the hub by the code on its label. The hub sends it the house's plan, shows its screen settings in plain words, and keeps the one setting that could stop the boiler behind our installer PIN.
Bosch's Zigbee Radiator Thermostat II joins and holds its temperature, but not all its settings show yet. Bosch boiler controls that run through an app account are a different range and are not on this list.
Danfoss
Works locally
Ally radiator thermostats (Zigbee), without the Ally gateway.
Each Ally valve joins the hub directly, so the radiator in the spare room can sit at 16° while the lounge is at 21°, on the same plan as the rest of the house.
A radiator valve warms its own room; the boiler still needs a thermostat that switches it, such as the Bosch. Ally valves can be slow to act on a new temperature.
SONOFF
Works locally
AirGuard CO₂ monitor (Matter over Wi-Fi), and SNZB-02P Zigbee temperature and humidity sensors.
The AirGuard joins over Matter with the code on its label, no SONOFF account, and puts the room's CO₂, temperature and humidity on its card: green while the air is fresh, red when it is time to open a window.
SONOFF's Zigbee radiator valve does not show all its settings on the hub yet, so we do not fit it.
What we leave out, and why
Heating controls that only answer through their maker's cloud are not on this list: the hub could not reach them with the internet down. Many popular app-controlled thermostats are in that group, so send us a photo of yours before you buy anything.
Not always. If yours only works through its maker's cloud, we fit one that talks to the hub directly, such as the Bosch Room Thermostat II. Send us a photo of your heating controls on WhatsApp and we will tell you straight.
Does the heating still work if the internet goes down?
Yes. The plan lives on the hub and the thermostats talk to it in your house, so the heating keeps its times and temperatures with the internet down.
Can each radiator have its own temperature?
Yes, where a radiator valve is fitted. Each valve holds its own room on the house plan. The boiler is still switched by a wall thermostat.
Does it learn our routine?
No. It follows the plan you set with us, Home 21°, Away 16°, Sleep 18°, and Boost 24° when you want it, and changes only when you change it.
