Way better than hive
I recently bought hive thermostat and it caused me so much headache. It kept disconnecting. So i bought the Netatmo to replace it. I did this install myself and it was a little bit confusing with the wires. My hive thermostat didn’t have a gray wire (it was cut off) so i thought this won’t need it either, but the relay wasn’t turning heating on when i put the black one only. I put the gray in the red slot and it finally worked. (Pic) I hope this helps someone else with an Ideal Logic combi boiler like mine.Massive feature for me is the hysteresis settings in the app. I didn’t know until now that’s what that’s called. You can adjust the threshold how many degree points it turns the heating on. Hive was automatically only 0.1 and it kept making my heating turn on for like 2 mins at 10 min intervals. I hated that. So big plus to Netatmo app for that.Install was pretty straight forward, now i wonder why did i ever get an engineer for the hive one. The one hiccup was the wire as it wasn’t marked on the boiler. But the rest was easy peasy. They have some old videos on youtube but your boiler might be different so it won’t match 100%You don’t need to use the app. You can connect the thermostat to the relay directly. The connection seems to be thermostat to relay through radio frequency. Then relay to router through wifi (if desired)But if you do get the app, connection to wifi was straight forward as well through the app. It uses 2.4ghz wifi but it was able to connect to my combined router wifi. It hasn’t had any issues with connection so far.In the app you have schedules and you can set different temperatures for different settings. E.g. comfort, comfort+, night. You can change each one to your preferred temps. You can also choose to have just one temp all day round. I am always home so i need same temperatures all day. But it is nice to be able to easily put it to automatically lower a bit at night. I attached some pics of the app schedules. (Don’t judge my high temps, I have lizard blood)There’s a boost option in the app which is nice, you can choose temp and time but it was a little bit unintuitive.There’s other smart self learning settings and apparently some PID heating algorithm that will be allowed to be enabled later on after it learns your system. But i don’t need any of that. I didn’t want it to try to be smart, i just wanted more control. Schedules, boost, hysteresis settings. All i needed.For the thermostat itself, it wasn’t intuitive that you just press the sides to increase/decrease temps. And the small numbers are hard to read at a glance. This is due to the minimalistic style. I have pretty good eye sight but i struggle to see if its 21.5 or 21.8.I regret not buying this during black friday sales. It would have saved me a lot of money.I read the general lifetime for this is 2 years. I will see if it’s true in 2 years time. If it is only 2 years I’m still happy with it.

Can be a pain to install, but worth it!
So I’ve been using these for a few months now, had a Netatmo thermostat for almost a decade and when these come on offer thought I’d try them. Honestly i thought these were a waste of money, but now I’ve fitted them and been using them for while I think they are amazing. Initially had a bit of trouble with them connecting but once the firmware on them updated issues disappeared. My main gripe is the plastic fittings, plastic on plastic seems to stick I had 2 remove a couple of valves as my actual radiator valves were seized, a bit of oil and gentle persuasion got them free and the valves work a treat. Having each room be independently controlled is brilliant no more cooking in one room with a cold part of the house. We have a boiler which I think is on the limit of our house and rooms tuning off as they reach temperature actually allows the house to warm up a lot more evenly now.Initially I thought the temperatures were not accurate and adjusted them using offsets in the app which you can set per valve, however after a few days I realised I was wrong and thermometers in the rooms didb match the thermostats, changed them all back to default and everything starred matching up.My only concern is battery life, each valve had a set of spares in, instructions say not to use rechargables, as I used grease on the valves to help the movement I’m hoping freeing them up will help with battery life, so far haven’t changed them yet but only had them I think around 4 months.Easily recommend, just wish they used metal rings for attachment!*edit*Just to update, I’ve had one valve fail but Netatmo support are pretty good to respond, But be careful removing and replacing them several times can cause the plastic to snap, sadly that has happened to one of my valves when checking the radiator valve. I will defiantly keep using them though as they are very simple to use. When changing the batteries it’s a good idea to clean the contacts otherwise the valve keeps saying the battery is low after a few days, using silicone grease on the underside helps with calibration errors for me, I’ve only had an issue with one valve though once. It seems like the batteries last longer than you expect but cleaning the terminals is a must as they seem to oxidise, or at least that’s what has happened with our troubled one.

Lediglich 2xAA benötigt. Arretierung der eingelegten Batterien ist verbesserungsbedürftig. Ansonsten empfehlenswert.

Achat du starter pack NETATMO pour deux radiateur dans mon appartement.Vanne très facile à changer soi-même i on a déjà une vanne thermostatique montée sur le radiateur.. on dévisse.. on revisse avec l’embout qui va bien et hop le tour est joué…Par contre, malgré mon installation très fiable en fibre chez moi, cela a été assez impérieux de bien faire fonctionner le relais en wifi je ne sais pour quelle raison d’ailleurs j’ai finalement réussi.. à part ce la , l’application est top mais aussi la version ordinateur qui est très pratique.. ce que j’ai apprécié de plus immédiatement, c’est la diversité des réglages possibles avec des plages horaires qu’on peut rajouter à volonter dans la journée et certains jours seulement.. une autre chose également plus que très appréciable, c’est qu’on peut définir et donc changer la température indiquée sur la tête .. en effet , on peut mettre la température qu’on trouve sur un thermomètre classique chez soi afin de bien avoir la juste température.. d’origine j’avais 26 quand j’ai mis la vanne alors que j’avais 22 chez moi.. j’ai donc changé en 22 degrés et hop .. c’est parti pour 22 dans la température ambiante de la tête.. facile donc.. en résumé.. .peut-être laborieux pour trouver la bonne place pour le relais et stabiliser la connexion avec l’appli et les vannes.. une fois en route tout fonctionne bien… on verra dans le temps car je les ai mises que depuis 3 jours !
