My wireless receiver daily loses the connection to the internet bridge - why?
My Tado system has worked seemlessly for a number of years and then in the last month or so has started losing the link between the wireless receiver and the internet bridge. The result of this is that the heating ether does not come on or stays on. Each time I have to reset the receiver and then it works again for a few hours or day.
There have been no changes to the position of either device.
Would welcome the community's view on the cause and solution. Does anyone else have the issue?

I’ve had this problem too, was working fine for a couple of years, even after changing broadband provider, but over the last month or so it kept disconnecting.
Our internet bridge then packed in altogether, tado sent a replacement but I can’t get it to pair with the existing tado stuff, and the old bridge still shows up in the app. I’ve moved it to somewhere else in the house in case that was anything to do with it and its now got all lights on it flashing really quickly but still not working.
No info on the Tado help pages on how to sort this, just bots on the chat pages, it’s really doing my head in and after two weeks with no heating and the first sub zero temperatures of winter our house is freezing.0 -

Similar issue here - first noticed a blip a few months ago. I got home after a few days away and the house was roasting hot as the heating had turned on and not turned off. I reset everything a few times and have had a few re-occurrences, but the last couple of weeks it’s got really bad - almost daily but at different times of day or night, either the boiler not turning on at the set times, or not turning off at all when the room temp is reached on the room sensor. The app often shows a grey screen ‘Offline’ though I have internet connection and the 3 lights on the Bridge are static.
The (wired) receiver blinks - so it seems to randomly lose its connection.
I have to reset the receiver, sometimes several times (and sometimes for good measure the Bridge too) to sort it out.
Tado’s been installed just over 2 years.
The positions of the devices haven’t changed.
I don’t have the smart radiator sensors.
It’s now doing my head in!!
Any thoughts on this?1 -
I have exactly the same issue and am seeing if I can get a response from the Tado helpdesk on this. When the bot says, 'Talk to an agent?' This is rather misleading as it is essentially an email system that takes 2 days to respond. @Emcee Could you please follow up on this discussion to get a response, as it seems to be a common problem?
The status of their servers, etc., shows everything okay on their end. I will share what response I get.0 -
Hello @SM51
Everything is running ok on our end. We did have a slight issue with Energy IQ from December 5-7, but that's it. The only advice I can give is the same Aida has given to you in relation to your IB placement.
Please stay in touch with support, Aida will likely escalate your ticket if the bridge is not the issue.1 -
Hello,
I fully understand about the IB placement but this does not explain how the system can work absolutely fine for 2+ years and then in October when the heating comes on it starts dropping out on, what is like, a daily basis. I will continue to follow up with Aida but I suspect that the IB is starting to fail. Do you have any reliability data on the v3 IBs?1 -
Same issue here. Did you ever get to the bottom of your issues?

Hi @SM51
Perhaps something similar to what happened to @Kev54 in the attached thread
Maybe a small change in the house has caused the signal to be disrupted enough to cause the drops.
Worth trying a WiFi extender with ethernet port or powerline adapter to move the bridge to a more optimal position?

My own solution was to extend the cable for the wireless receiver and move it much closer to the bridge. The two have never lost connection since and the bridge remains in the optimum position to communicate with the TRVs . . .

How far did you move the receiver from the boiler?0

TL;DR Try a passive aerial - it seems to be working for me.
I’ve been battling persistent dropouts between my internet bridge and wireless receiver for a while. It also started towards the end of 2024 after being stable for a couple of years. Very frustrating with sometimes multiple disconnects a day, and problems most days. I thought it might be caused by conflict with my Hörmann garage door remote but general testing including relocating my bridge led me to conclude it’s just weak link quality.Moving the bridge didn’t work. To get a stable receiver connection meant the bridge could not see some of my TRVs. Support did what they could (changing RF channels etc.) but the core problem remained: the wireless link would drop, then take anywhere from 20 minutes to three hours to reconnect, depending on how the retry timer behaved, and Tado support could neither confirm retry time nor talk to a developer about changing the firmware. They also categorically said that a second V3+ internet bridge was not supported and would not work. That contradicts some experiences I’ve read about, but I haven’t tried it myself.
Anyway, I reached the end of my tether when support suggested I just buy a new wireless receiver which was their guess at the problem.
After some Googling, I tried a simple passive trick: I tie-wrapped an 86 mm length of 1mm copper wire (quarter wavelength for 868 MHz) vertically on the outside of the internet bridge. This effectively acts as a crude passive whip aerial to improve the bridge’s radiation pattern and slightly boost signal towards the receiver. I installed this on the 12th of June. Since then, I’ve had one brief 9-minute dropout on the 18th and nothing since. That’s a massive improvement over daily dropouts.
It’s a simple, cheap fix that might help others in marginal link setups, especially if your bridge and wireless receiver are separated by brickwork or suffer interference from things like garage door remotes. It won’t magically fix everything — but for me, it’s turned the system from unreliable to stable with minimal effort. Worth a try if you’re stuck!

@thefern Hello. Thank you for sharing your experience of improving the radio range of V3+.
FYI, Tado V3+ appears to use the IEEE standard 802.15 and 6LowPan. The IEEE 802.15 standard is specified for IOT devices with a design range of 10 metre and low data volumes. I'll add your postive findings to the possible solutions.
