T6R Smart Thermostat works with Apple HomeKit and Amazon Alexa replacement for NEST, TADO, ...

Really impressed with this thermostat. The WiFi connectivity makes it easy to control from your phone, whether you’re at home or away. Setup was straightforward and the app is simple to use. It’s reliable, accurate with temperature readings, and responds quickly to changes. Having easy access to adjust heating remotely is very convenient. Overall, a great smart upgrade for the home.

The world of 'smart' house heating controls is huge and confusing - and I include myself in this even though as a Marine Chief Engineer I have worked on high voltage construction vessels that would confuse military experts. The market seems to boil down to two types. The first type is probably the most common which is the type that simply starts and stops your boiler according to the settings along with all the other bells and whistles chucked onto it. The other type is more sophisticated and also relies upon individual radiator controls. Both of these do not entire work for those of us who had a dual zone plus water tank system fitted. There are also other issues of course. If you add up the cost of WIFI rad valves across your house one has to question the bonkers claim that these will save you money. Honestly, even after fitting this I'm 100% certain I will never get back the money I've spent on the miniscule fuel savings. I'll digress here a bit as well. I'm a marine engineer and as such I've worked on VLCC steam ships in my yoof. Steam ships are basically big thermodynamic experiments that use epic amounts of fuel. We would easily burn through 150 tonnes a day, so any saving no matter how small is easily seen and useful. And this is how we do it. Turn the temperature down. No, really. What we did was open up the main steam valves fully. 100% open. This is important because throttling is really inefficient. Then we dropped the main boiler pressure down to match the turbines with the control valve fully open. This is the most efficient way of not using fuel. If you take a house, every time you fit a thermostatic valve you are throttling water and this is inefficient becasue in order to maintain control temperature you need a high water temperature. And heating water is a logarithmic curve. The higher the temperature the more fuel you need un an upward curve. This is why underfloor heating is efficient. A large area with water heated to 36c not the 65c for rads. So what I do is not throttle my rads. Instead I have turned my water temp down to 57c which is above the level required for killing legionnaires but requires significantly less fuel to maintain. Anyway, going back to controls I could not find anything that met my needs exactly because a there are no dual zone + water smart systems. What there is, is this. Becasue basically what all these smart controls come down to is a remote controlled switch and this is just that. A typcial dual zone system consists of a dual zone controller - which simply puts power onto the mechcanical thermostat at set times. This thermostat will then open up the zone valve which will send a signal to the boiler to start. So, if you have a dual zone system, ignore the blurb in the Honeywell instructions, because its about direct boiler control and, well you can't do that immediately. What I did was install this in place of the thermostat in one zone and using the 240v feed to the controller power the hub unit - which the instructions say to mount close to the boiler and which I didn't. I of course played around with this on my bench to make sure I had it right then temp mounted it once I figured the best way to do it. See the pictures. You then set your original controller to 24/7 on for the zone this is controlling. From then on, this smart controller will control the temperature to your settings which you program in. Of course if like me you have got one zone working on this then inevitably you will want to do both and that means another controller. Once I do that I'll rewire the system and remove the original controller complete. Now, the only bugbear I had was setting this onto my wifi network which took me an age. The blurb is not 100% clear and I was getting frustrated. Bottom line is that you have to use your phone/tablet to log onto the Honeywell wifi - then step back using the back button. It is noted but easy to miss so read very carefully the information and carefully check your app. It does work well once you understand it. Anyway, once you are on line you can do the usual. Set up a calendar for on/off, geographic operation which means it will start up or stop depending how close you are to your house and of course allow manual remote control. A quick word about geographical operation. If like me you have a lousy mobile signal at your house you might have fitted a mobile booster that uses your internet. Which also means your location isn't your house, so you have to go and find an actual signal close to your gaff to set that up. Once fitted its a neat system that is easy to use looks smart and allows excellent control.

I’ve been using two of these thermostats for over a year, in a dual zone setup (downstairs and upstairs) and they have been working great. The thermostats have a lot packed in, including the ability to schedule your heating and setup geo-fencing to automatically turn on and off your heating when you leave home. You can only use one or the other, which is a shame as it would be good to have a schedule in place but also the ability to turn off the heating if when you leave and then jump back to the schedule once home. All these controls are setup through the Honeywell Home app, although I prefer to use Apple Home once scheduling has been setup. These thermostats are OpenTherm compatible too, so they’ll modulate your boiler to help save on gas usage. They also have an ‘optimise’ feature, so they’ll measure how long it takes for your home to heat up, so they can start pre-heating to your desired temperature. This basically means if you set your heating to be 20c at 8am, it may turn on at 7am to start warming the house so it’s at the desired temperature by 8. It’s great for those chilly mornings! So the reason I’ve given this 4 stars for now, is I added an extra zone valve to my current setup after adding gas heating to our garage. I purchased an additional thermostat and setup everything. A week after however, it stopped responding in Apple HomeKit and would no longer connect to WiFi. I haven’t had any of these issues with the other two thermostats so I’m hoping this will be solved with a replacement.

Bonjour à vous Je suis entièrement satisfait … Le thermostat fonctionne tout à fait conforme à ce que j’attendais … La livraison s’est parfaitement déroulée … comme chaque fois avec Amazon

Ich bin mit dem Thermostat sehr zufrieden. Der Funkempfang vom Dachboden bis ins Erdgeschoss war absolut problemlos und durchgehend stabil. Auch die WLAN-Verbindung lief von Anfang an zuverlässig ohne Abbrüche. Über die Resideo App lässt sich die Temperatur jederzeit und von überall aus einstellen, was im Alltag sehr praktisch ist. Die App ist übersichtlich und die Bedienung funktioniert reibungslos. Die Installation über OpenTherm war unkompliziert und innerhalb von etwa 15 Minuten erledigt. Insgesamt wirkt das System modern, gut durchdacht und zuverlässig im täglichen Betrieb.

Très simple d'utilisation et fiable. L'interface du thermostat est plus complète que celle d'autres modèles (voir photos) : pas besoin du smartphone pour modifier la consigne de chauffe pendant une période donnée. Évidemment comme tout thermostat connecté l'application permet de programmer en détail et surtout à distance. Le sel bémol, légèrement plus compliqué à câbler qu'un Netatmo par exemple.

Lo tengo instalado desde hace 6 días aprox y por el momento funciona a la perfección. Interface muy intuitiva, fácil de usar desde el mismo termostato, pero más fácil aun desde la aplicación. En mi caso tengo el inalámbrico que para mis necesidades va genial, lo puedo poner donde quiera y prefiero que vaya enchufado y no tener que estar pendiente de las pilas, pues los inalámbricos con wifi y pantalla táctil las consumen rápidamente. LA INSTALACIÓN; es sencilla, bien explicado en las instrucciones, yo en mi caso como tengo la caldera en el exterior, para evitar que se moje el receptor (que es el que se ha de conectar con 2 cables a la caldera y otros 2 a una toma de corriente) lo he instalado dentro de un armario dentro de casa, aprovechando que en el armario tengo el cuadro general de luz donde he cogido la alimentación para el receptor, para la conexión con la caldera he pasado 2 cables desde ahí hasta la caldera y todo funciono a la 1ª. LA COMUNICACIÓN TERMOSTATO-RECEPTOR; con una distancia de unos 4 metros y receptor dentro de un armario es muy buena, sin desconexiones. LA CONFIGURACIÓN DEL TERMOSTATO; (usando Android) fue fácil hasta que llegue al punto donde se tiene que poner la contraseña del wifi, me daba fallo de conexión, lo pude solucionar gracias a que leyendo los comentarios de usuarios vi que alguien dejo un comentario de que se tiene que desconectar los datos móviles del teléfono para que el termostato detecte la red wifi a la que está conectado el teléfono, esto deberían ponerlo en las instrucciones. EL WIFI; por el momento no se ha desconectado nuca en este tiempo. LA TEMPERATURA; que marca el termostato es correcta comparándola con la que me marca un termómetro que tengo en el mismo sitio, marcan lo mismo. MI VALORACIÓN; por ahora es muy buena, era de esperar ya que esta marca es de las mejores en termostatos.

Heel eenvoudig te installeren en makkelijk in gebruik. Enige minpunt/is dat de thermostaat continu in het stopcontact moet
