Heat Link from Nest 3 learning thermostat disconnects (heat link) every day during 30 minutes

[FredClement91]

Hi all,

I already saw a lot of posts about this problem but no solution.

My thermostat is disconnecting (heat link) once or twice a day from the receiver.

I tried to reset, factory reset, bring the thermostat near to the receiver, nothing helps.

And without doing anything, it gets back to normal after about 30 minutes.

Has someone here the same issue and found a solution ?

Thanks

I take it you are using your thermostat as remote, and not wired? This problem can be caused by interference from anything, ie microwave, DECT phone, things like that. Do you have anything of that nature in the home? Try isolating any item that could be the issue, and see if that helps.

Hello there! Thanks for posting and I'm really sorry to hear about your intermittent issue with your unit. As @Frustratedddd mentioned this might happen due to any physical interference. Such as wireless devices, walls, pipes, magnetic filters, cordless phones, microwaves. Also, do you get any error message when the devices disconnect?

Hi there, just checking in! Did you see the message from my colleague?

Hi, 

sorry for answering late.

I tried to put the thermostat very close to the receiver, so I don’t think that interferences are the cause.

But maybe I found a reason.

I noticed that the Wifi of my SFR box is really bad, and I have other devices also disconnecting from Wifi.

I added an new wifi access point and connected the thermostat to it.

For now all is working fine. I will let you know if I have some new issues.

Regards,

Frederic

I'm glad to hear that it is working fine now! Is there anything else I might help you with, in the meantime?

Not for now, thanks, I hope it will stay like that
