I have external access issues with my radiator valves as well. Customer service tried switching channels which didn't work. Now they sent an email suggesting a replacement of the bridge. On reading this thread, I doubt that will make a difference. Also, since the need for a repeater/extender has been a point of discussion for a few years already, I am not convinced tado will ever deliver it.
Still, the radiators that are unstable are only 5-6 meters away from the bridge. On buying tado I never ever considered connection stability could be the issue annoying me most with the system. I guess you live and learn. Not sure if anyone here is aware of how competitors like Netatmo are doing.
I am also so disappointed regarding the support from tado. A year before I invested for two room thermostats. It was fine, and during a system upgrade I extended the system with several radiator thermostats and an extension kit.
Du to that I had to relocate of internet bridge due to continuous disconnecting of one radiator thermostat. Since September almot everything is fine, but there is one issue bothering my user experience.
In each 15 days one radiator thermostat gets unreachable/disconnected. So Extension kit goes to fall back mode (continuous light and two times blinking).
I contacted to support and as answer they released a copy from user manual: I shall move internet bridge closer.
It is not possible from me. During the last weeks I experiences how to solve this issue. By restarting internet bridge (plug out from electricity and after 10 sec plug in) the radiator thermostat becomes visible and full operational again. With extension kit there is nothing to do. after the first operation from the "lost" radiator thermostat it gets back to normal operation.
Before I tried to restart it, but it does not help, just pushing extension kit to another error mode.
From my understanding such issue may be caused by SW issue and kind of weak connection. I cannot believe radiator thermostat signal get tired always after 15 days. Always in the evening...
Support does not help. And it making me so disappointed, because based on the description I would expect kind of normal range to cove a two flat House. So a medium size.
It seems to be for me Tado does not care really about range issues. No reply here, and support best recommendation to relocate internet bridge to the center. (It is almost there for me...
So now if any of my friends asking, I recommend Honywell... :( However Tado design looks better for me.
I have been having similar issues to everyone else. No matter where I placed the internet bridge, I could only ever get one of the TRVs at either end of my house to connect consistently with the other always dropping in and out.
Using the photograph in Wandal's post on this thread I soldered a short length c9cm of copper wire to the antenna on the internet bridge board. For the last 3 days, all my TRVs have remained connected. Too early to tell if battery life is affected, but so far so good.
Any joy with your soldering modification?
@Cash99 @Mike_T - can you post some pictures with your workarounds?
I too am suffering from Tado's lost signal, with my house cold most of the time since installed them 2 months ago.
Is there any lawyer around here? Can we sue Tado for selling these products?
@Liviu If you are in the UK you could try and claim that the products are not fit for purpose under the Consumer Rights Act 2015, but this will be against the retailer and not the manufacturer.
Suing and consumer rights act seems a little excessive.
Just ask the supplier to return them stating they don't work (if they don't work in your property).
Can you imagine people suing their wifi router suppliers when they don't get a signal in the bathroom?
In the mean time, I'm currently trialling a homemade passive repeater. So far had some reasonable results but need to test more thoroughly before I report back.
@Pete The advice was for the benefit of the OP. Please feel free to ignore it.
Has there been any progress with improving the signal propagation of the 868Mhz radio link from the Internet bridge?
Ideally Tado will realise that the bridge <-> TRV wireless links are so flaky that users will start to 'vote with their feet' and, as such, it presents a real threat to the business.
I have 11 x Tado thermostatic radiator valves in a moderately sized home and, like many others, I'm seeing signal outages far too often to be able to recommend the system.
I understand that, due to the need to conserve battery life, the TRV's cannot create a mesh network so it really does seem that the obvious solution would be for Tado to produce a powered 868Mhz signal repeater. Given that they have already engineered the wireless communications between all the devices I fail to see why manufacturing one is proving so protracted.
Inspired by the posts here i modded my bridge yesterday. I cutted the old antenna on the pcb and soldered a slim wire from an old usb cable instead. I used 8,6cm and drilled a hole to the case.
My findings are, that the signal is not generally better, but for it helps that i now can move around the antenna without having to re-mount the whole bridge. For me all radiators ore online now since 1/2 day. Prior the outer two lost their contact every hour for some minutes.
Additional interesting finding: I have a second, unused bridge that has more chips and sma connectors. I do not know if it is an older or never version... maybe a V2? This is something i will test when my soldering experiment fails, but i do not have sma antennas at hand. Maybe time to kill an old laptop...

Thanks… I’m pretty sure it wasn’t there before!! But it is now.
Photo of the bridge (I was calling it something else!) in it’s new location, a bit ugly, but it works 👍🏻:
Screen cap of all my rooms working properly.
Will report any improvements to the two radiators normally out of range…
interesting ! will try that out…
