surely the Internet bridge that the battery devices connect to is also wiFi ?
This topic as been ongoing for years, but still Tado do not listen, for any smart system to work, whether it be a heating system or any other function, THE major component in the ecosystem is connectivity. It has to be stable and reliable and quite frankly it is not with Tado unless you live in a bungalow with paper thin walls. Most people who can afford to invest in these systems also tend to live in larger properties, have you still not worked it out Tado.
please listen to your customers and adapt backend architecture to permit either multiple internet bridges with sensor clusters or develop an internet bridge extender.
It's strange isn't it? I live in a large sprawling farmhouse with very thick stone internal and external walls, and never get a single disconnect from 14 trvs all around the house. Have been running for over three years now. Using cheapie batteries used to be an issue, but sticking to Duracell Ultras has solved that.
Could there be other external interference in some houses that causes this issue for those reporting here?
Glad I found this thread while checking compatibility and communication from the bridge. I live in a grade II listed stone cottage that has been extended. The older cottage has 1ft thick stone walls and the extension of modern cavity wall construction/internal block work walls. The entire house is now 'L' shaped. We knew we'd struggle with wifi when it was extended so we had the forethought to install Cat5 during the build. As such we have two wifi access points. One for the old part and one for the new. Both connected back to the internet router via Cat5 and share the same SSID. This works perfectly fine.
After reading the specification then spotting this thread, I've since emptied my basket of £900+ of thermostats and TRV's 'voting with my feet' as someone put it.
I understand that it's not feasible to have the TRV's acting as a mesh due to power requirements but as many have said, it would make great sense to have more than one bridge, and for the bridges to talk to each other over ethernet. I could simply connect a second bridge to the access point in the new part of the house and all would be great. It seems to be a common problem in a large number of homes and from Tado's point of view, these clients with larger houses are the ones that are going to spend the most.
Tado support told me "Yes, it is a common issue. But technically 2 tado° Internet Bridge would not be able to work together, since the radio frequencies would interfere."
Isn't that worrying though? If your neighbour also installs Tado, they're basically saying it'll break yours. I don't think so! There must be some sort of channel bands, even on 868Mhz, otherwise any device would kill usage of all the others around it.
And if that's the case (multiple channels), why can't you just run two internet bridges on two different channels!?
Yes quite, same as wifi channeling. My phone, laptop tablet dont have an issue switching to the strongest access point and they're different manufactures (Virgin Hitron / Netgear).
Not only that but the tado device is 'paired' to its thermostat anyway right? So you would presume it would just listen/poll for its paired bridge on that frequency regardless. You might have several bridges blasting out crap at 868mhz, your neighbour included... but if its pared, its only going to communicate with that? or whats the point in paring?
Ill stick with my google thermostat for now and await some updates.
@Pete Sorry not wifi but bluetooth.
Actually it is really easy to see where the antenna for 868 ends. It is in the bottom right corner of the picture that @solbadguy2010 posted of the second bridge he has. It is the side with the reset button.
I have had similar issues, but they have improved recently. Like you @BigJeffUK we have a large old L shaped stone farmhouse. This may help others, my issues are not gone away, but we can live with it now and have far less dropouts than before. I shouldn't have had to do all the below but after a £1k investment and a desire to keep my oil costs reasonable I decided to persevere and do what I could.
