NETATMO nav-ES – Smart Valve Additional Radiator, Multi-Colour

These are so easy to fit and set up. I have done a few and have not needed instructions. Just remember to use the button on the relay to put it into pairing mode and that's it

Not sure why other people are having issues, took me less than 10 minutes to install via the app, and after reading the instructions i installed the valve on my radiator with no issues. I would suggest you read the instructions first before starting the overall installation process. Works perfect no issues and now i can control the heating in every room in my house.

I would give it 5 stars if the instructions were better (and honest!). Installing the radiator value was a little problematic. I added the adaptor to my radiator with no issues but when I tried to screw the value onto the adaptor, at the limit of my strength it still wasn't on properly and this resulted in the mechanism not marrying up to the radiator properly. The only way I could get it properly fixed was to use a wretch. A few good grabs and twists and it's on but alas a bit scratched up as a result.It did some strange things when I first installed it and I wasn't convinced it was working but then it showed the temperature and about 20 minutes later appeared in my Homekit. It took about 3 days before I could actually see it on the front page of the Netatmo app though.The only thing that seems amiss is the ability to individually control temperatures, My expection is:- Room 1 and Room 2 both have a valve and we also have a Netatmo thermostat in a 3rd room which ultimately turns the boiler on and off- If I set Room 1's valve to a higher temperature than the room currently is the thermostat shows the requested temperature target and fires the boiler (expected behavior) - What also happens is Room 2's valve also shows the new temperature target so presumably opens the rad to allow the hot water in - If I want to set Room 2 to 16 degrees and Room 3 to 20 degrees I would expect the boiler to heat until Room 3 reaches the 20 degree target but I would expect Room 2 to close the valve and prevent any further heating once it hit 16 degrees. This doesn't happen and it sort of defeats the purpose.I'll keep an eye on it but it's not working like the promotional video (from over a year ago!) shows

I had new radiators installed and the engineer fitted these as per my request, as I already had the relay fitted. Unfortunately one of the valves started to lose signal with the relay. I contacted Netatmo's customer service and after a very long wait they got back to me. Lots of emails back and forth trying resets and talking about moving the relay closer to the radiator until they accepted it was faulty. The trouble is, my engineer has since shut his amazon account so cannot provide a reciept, so Netatmo will only repair at a cost of 44 Euro and postage to France! so that wouldn't be much cheaper than buying a new one. I cannot contact Amazon without acutally buying the product from them myself so I'm stuck in the middle. If anyone from Amazon reading this can offer advice I would be extremely grateful.

Here is my email to Netatmo support, plus their eventual reply:Hi, i have been waiting a year for the valves to arrive and i plan to install several. But in trying to install my first radiator valve, I have 3 issues: 1) the valve wont connect to the app. The arrow symbol comes on, but the app never finds it. I have removed and replaced the batteries many times. I have checked the batteries. The valve is about 5 metres from the relay in an immediately adjacent room in an area with good wifi. Now there is a big exclamation mark to the left of the temperature. And now its a straight vertical line on the right and the temperature has disappeared. 2) if i use the manual overide to stimulate the valve to close or open then it does nothing - or whatever it does is so silent that i cant hear it sitting right next to it. Is this because it hasn’t synchronised, or is the whole thing faulty? (Now i cant even try to do manual overide as it has gone into a permanent vertical line on the right - and yes of course i have tried taking batteries out and back in) 2) your valve instructions are so bad, i mean so so bad, that i nearly didn’t bother and sent the whole thing back. This is pathetic. I installed the thermostat with no problem following your excellent instructions, so why oh why have you not even thought for 1 second about the valve instruction book. Do you really think people want the valve without connecting it to the internet/ app? why else is the app and iintegration and connection not mentioned at all in the instructions. The instructions “test” doesnt even test wether the valve controls properly the plunger or not! - the most fundamental function of it works. The instructions dont tell you to expect the wifi arrow stmbol instead of the temperature...... i despair at the idiocy. Please help.12 days later the reply:Hello,Thank you for contacting netatmo support.I've just checked and your Valve is well connected to our server as the Thermostats.Can you please confirm that you resolved your situation?If this is not the case and if you still having question, feel free to contact me again.Thank you for your understanding.Have a nice day,
