The "Window open" function can only be switched on or off, the default value is 3 minutes, this cannot be changed. According to the information in the help, all thermostats in the affected room are switched off. I have not tested it yet.
I operate 20 valves in an old house with thick walls and 10 rooms on 3 floors and this works with only one relay. But I had to test several sockets until I found one where the relay could connect to all the valves.
The Netatmo valves are also thermostats. Your Danfoss valves have already reacted to the room temperature. The Netatmo does that too, but much more precisely and you can control it from anywhere.
The Netatmo Starter Pack, which includes the Hub, is a basic package that forms the basis for the Netatmo smart home system. The thermostat itself is a separate device that can be added as an option to control the radiator thermostats.
You only need the thermostat if you specifically want to make the radiator thermostats in your home smart and control them via the Netatmo system. The Starter Pack allows you to set up the network and integrate other Netatmo devices, but it does not automatically include the thermostat for the radiators. This must be purchased and installed separately.
Yes, you need a gateway that connects to Wi-Fi and the Internet.
The weather station can be added in the software to add additional management functions.
PS: I have a gateway and 7x heads for sale second hand.
I don't think it works. The head has to be in the same room, as it has to be able to measure the temperature. With underfloor heating, all the valves are usually centralised in a technical room.
I have adjusted the True Temperature on two radiator thermostats by I think 1.5 gad, as these two thermostats are very low to the ground. Now they regulate perfectly.
Yes, that is possible. There is even a frost monitor in the app so that the temperature never falls below a certain level.
Using the thermostats, you can also always see the temperature on the individual radiators. If the battery is not empty.
Exactly: control unit + 3 controllers. What I hadn't considered myself: the control unit contains no operating elements, is simply plugged in and controls the whole thing. It is operated exclusively via the app.
Thank you for pointing this out. Since a set price does not automatically adjust to the individual prices, it can happen that the set price is higher after a reduction of the individual price than if the individual items are ordered separately.
Hello Mu31
You simply need a smartphone/tablet and download the Netatmo app "Energy".
Apple: https://apps.apple.com/ch/app/netatmo-energy/id730893725
Android: https://play.google.com/store/apps/details?id=com.netatmo.thermostat&gl=CH
Then "Install new product" in the app. You will then automatically be asked about WLAN. It is not possible with an Ethernet cable, correct.
There are various good videos/sites that also helped me to get an overview:
Overview page
https://www.netatmo.com/de-ch/energy/valves/installation
There you will find video instructions, e.g. right next to the picture sections "Thermostatic valves" or "Manual valves".
Further down, in the section "How it works", there is another similar video, or a PDF manual.
As stupid as it sounds, it's actually quite simple - but somehow not. But the videos helped me.
Important:
Don't despair. Be patient. Especially when the thermostat valves show the exclamation mark. (as soon as you insert/remove the batteries - or restart the relays) Always give the system enough time, approximately 5-15min.
Also, if it happens that the thermostat motor is at the very back and has no contact with the heater pin, give the thermostat time. Or you can always restart the relay (the settings / WLAN are retained).
Furthermore, after 2 months the original batteries were empty. Instead of replacing the batteries again, I took them out and put them back in. Since 3W it has been quiet in any case. Unfortunately I don't have a battery tester at hand - but I hope they are not effectively empty. Apparently they should last up to two years.
PS. You can change the temperature for "Frost monitor" and "Absent" in the app under: Settings > My plan > at the very bottom on "Change temperatures" > at the very top (!) set frost guard / absent.
Hope I could help a little
Kind regards Actino
