Real, independent and effective heating control
Firstly I will say I do not normally write reviews but this product deserves it. The system I fitted these to is an old oil fired open system. It was already controlled by a Netatmo thermostat that I had installed several years ago along with 3 electronic radiator thermostats with the remaining radiators on standard wax based thermostatic valves. The system worked adequately and the ability to control the heating via the internet was a great advantage. However it wasnât perfect. The problem I had was that the thermostat was in the hallway, as in many homes, with an open kitchen which meant whenever the oven, cooker or tumble dryer was switched on the thermostat would have a false reading, the hall was warm but the rest of the house wasnât.As some of the old electronic valves had started to fail I decided to replace them with the Netatmo valves as they would be part of the same system and could be controlled from the same app as the thermostat, which I couldnât do before. What I didnât realise what that the valves not only opened and closed the valve when the room needs heat but they can also âcallâ for heat and turn the boiler on, something the marketing blurb did not make clear. On first thought this may not seem important but it cured my open plan kitchen problem instantly, it no longer matters that the hall is warm as other rooms can call for heat as it is needed. It also means that the hall isnât kept warm just so the lounge has heat, something I suspect anyone with a central thermostat will have experienced. It has also cured a problem of heating bedrooms, most people want to warm bedrooms at a time when you have settle down in the lounge for the evening. The lounge is nice and warm, the hall is already warm and you donât need much âtop upâ to keep them comfortable but the opposite is true for the bedrooms. With these valves though the bedrooms are controlling the boiler so are comfortable for when you retire. In effect it is like having a zoned heating system with control in each room without ripping out and replacing the entire heating system.Now everything has positives and negatives. On the down side is the strength of the radio signal (not your Wi-Fi) mine is a 1960âs home with concrete block walls not wooden framed so some experimentation was needed to find a good location for the relay. Firmware updates seem to happen at any time of day or night, not something you want in the middle of the night if you are a light sleeper. The ability to delay updates to a certain time would be of benefit. You also need to have existing valves that are in good condition, I had several that were a little sticky. This seemed to cause a bigger drain on the batteries and the unit asked for them to be replaced. Changing the valve bodies, a simple enough job to do, cured the problem but it is something to be aware of.Overall I wholeheartedly recommend these electronic valve heads, they are simple to install and use, look great and have already started to reduce my oil consumption which will result in a cost saving. However for me the greater control and resulting balance of comfort and convenience is far more important.

Good system which is easy to install
It was a cinch to install. The video installation guide from Netatmo, made it super easy. It was very easy to set up. I had to unstick one of my existing radiator valves to get rid of the “calibration failed” message. So far so good except that the heating hasn’t been on much with the mild weather. One gripe is that the batteries they supplied for one of the valves ran out after 5 days. Overall though I like the system.Update: I have now installed another two valves. Both ran great until I ran into the battery power problem the which has been mentioned elsewhere. I removed the valve and moved the actual valve on the radiator up and down a few times to make sure it moved freely. I reinserted the same batteries that were meant to be flat according to the system and all is now working well again with reading showing full batteries. If it happens again I will return the unit for a replacement. I already replaced one.

Trv to control each radiator in a room separately to the rest, great
Bought ages ago and only got around to fitting yesterday, heating system failed and old controller gave up so I fitted these and the netatamo controller for my dad as he had lost all heating, these are a breeze tofit and extremely easy to set up, the only gripe is the WiFi controller at times was hard to link but these trvs were a dream and so easy to link.He is over the moon now and very happy as he will no longer come home to a cold house after he’s been out for the day or holidays as he was for over a month and came back to his system failing. Great quality thanks

Worst purchase I ever made
I am not exaggerating when I am saying that this is my worst tech purchase ever, and I am a techie. I would recommend NetAtmo thermostat as it proved reliable for 5 years and had to reset it only two times during this time but the valves are a product that should just be retired from the market because they are broken in too many ways. Two valves broken within two months of use, one because the original batteries leaked inside it and even after cleaning the valve no longer works. If found the second one with the clam broken even if nobody touched it (was in a secluded area), a clear sign that the plastic clamp brackets are not suitable as the temperature stress breaks them. Even the ones that work are extremely annoying as they produce a notable sound when the central system decides to retune them, basically multiple times during the night. I am now going back at the classic manual valves that worked just fine and without multiple adjustments during the day. Don’t buy them and if you can still return, return them as I am 100% sure all of them will be broken before the end of their first winter. Should I also add the fact that these beasts do consume lots of batteries? I think a pair of new alkaline batteries does no last longer than one month, two per valve.

Preso prodotto dall’UK, un po’ titubante per la compatibilità ma alla fine ho riscontrato che non vi sono incompatibilità .

J’en avais commandé 4 au départ pour voir l’efficacité de ces robinets j’en suis très satisfait à tel point que j’en ai commandé 3 autres tout mes radiateurs sont équipés j’apprécie particulièrement le suivi de ces robinets grâce à l’application qui permet de voir l’activité de chaque robinet avec la courbe qui me donne l’information du pourcentage d’ouverture de vanne et de la fermeture lorsque la température de la pièce est atteinte sans oublier la programmation pour la semaine que du bonheur merci

Attention ne fonctionne pas sans le transmetteur,uniquement une tete supplémentaire.Si vous voulez pouvoir lâutiliser il vous faudra acheter le transmetteur.Soit avec le thermostat dâambiance qui pourra piloter votre tête.Ou avec le pack transmetteur et 2 têtes.Je nâai acheté que la tête alors aucune utilité.Jâai racheté le trans avec le thermostat dâambiance.

Ich habe mir nach einem Testvergleich zwischen Netatmo und FritzBox Thermostat 301 für das System von Netatmo entschieden. Hatte schon zuvor bevor wir umgezogen sind das Netatmo mit Gas-Etagenheizung betrieben. Das hatte super geklappt mit dem zentralen Thermostat.Einige hatten schon bei den negativen Bewertungen geschrieben das sie Probleme hatten mit den Kunststoffadaptern und man sie schnell kaputt machen kann. Ich hatte bei dem Testvergleich vor einem Jahr die gleiche Erfahrungen gemacht. Das hielt mich trotzdem nicht davon ab auf Netatmo zu setzen weil einfach die Software und Bedienbarkeit unschlagbar ist im Gegensatz zu Fritz dect 301.Ich kann einen guten Tip geben wie man sie leichter montieren kann die Adapter. Am besten den Adapterring zuerst in die Verschraubung vom Thermostat Schrauben und dann das komplette Thermostat auf den Heizkörper aufschreiben. Dabei das ganze Thermostat um 360grad mit drehen bis es fest ist. Dann das Display in gewünschten Sichtbereich drehen und dann die silberne Verschraubung fest drehen per Hand. Man braucht keine Zange, per Hand ist es ausreichend fest.So hatte bei mir die Montage wunderbar geklappt ohne das Kunststoffgewinde zu beschädigen.Einige hatten auch geschrieben das man wenn man Schicht arbeitet nicht jedes einzelne Zimmer einstellen kann. Habe es am Anfang auch nicht gleich gecheckt wie Netatmo das programmiert hat.Man kann tatsächlich nicht jedes Zimmer für sich programmieren sondern es müssen immer alle Zimmer mit einbezogen werden in dem jeweiligen Zeitfenster.z.B. Heizen von 8-12 Uhr aber nur Wohnzimmer von insgesamt 5 Räumen.Dann muss man Wohnzimmer 20 grad einstellen, Schlafzimmer, Kinderzimmer, Bad, Esszimmer auf 16 grad. Dann heizt nur das Wohnzimmer.Wenn man dann doch von 10-12 Uhr das Kinderzimmer auf 20 grad haben möchte muss man wieder ein neues Zeitfenster für alle Räume erstellen. Dann mit Wohnzimmer und Kinderzimmer 20 Grad und Schlafzimmer, Bad, Esszimmer 16 grad. Und so Reihen sich zb vier, fünf Zeitfenster hintereinander bei mir pro Tag ein. Vom aufstehen morgens bis abends schlafen gehen.Mit Siri lässt es sich auch gut steuern. Was der Vorteil ist mit Home Kit. Wenn die Server von Netatmo streiken zB so wie am Black Friday kann man die Thermostate trotzdem manuell über Apple Home Kit einstellen oder per Siri oder eben manuell an den Heizkörpern selbst das ist klar.Fenster offen Erkennung ist noch nicht per Update gekommen aber ich hoffe das der Zusammenschluss mit Legard Synergien besser bündelt und Verbesserungen an der Software schneller umgesetzt werden können.Ich kann die Thermostate absolut empfehlen!
