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.
i have te same problem , distance to d some radiors to big , is a pity ,nice system but this is a tado killer.
i did some investigation it works on 868 with a wifi protocol 6LoWPAN which is open, the protocol is promising and could function perfect with mesh but if tado implements it idont know, there are OfCourse versions and different sub implementations which toado uses is not clear yet
is has the ability for a mesh network,
but tado goes raus if it is not making a repeater or implemts the mesh functionality
I'm considering ripping my entire Tado system out because of this issue.
I can't believe the system designers made such a fundamental flaw in the design and after all this time have still done nothing to rectify this problem.
The communications of the TRV's and the Solitary Crappy Internet Bridge is a joke for anyone with a reasonable sized property.
I been putting up with this since day 1 and have a significant investment in Tado with 14 TRV's. Some of which are still in the box because its pointless installing them when the Internet Bridge is incapable of communicating with all the current ones no matter where I place the bridge......AND I only have a large but single storey home (bungalow).
I am not putting up with another Winter with cold bedrooms because the signal can't reach the TRV's, if Tado don't finally come up with a solution, the whole lot is bring ripped out in favour of a WiFi version of TRV's (which I know won't suffer from communication issues) because I have my home blanket covered with Ubiquiti kit.
I won't go quietly either TADO!
@johnbur re: "WiFi TRVs are a non starter unless you want to be changing batteries weekly."
Incorrect, the TRV's I'm considering have rechargeable batteries and only need connecting to a charger once every 2 years (based on a 5 month heating schedule). Even if that claim turns out to be widely exaggerated and it ends up once a year, that's still as good a Tado without having to pay for expensive Duracell's.
@cheffo75 You're right and this is a small thread, there are many other threads complaining about this problem, one I was reading yesterday was 11 pages long with people complaining about this issue since 2017. That's not to mention other sources, I've seen lengthy reddit posts about it and of-course, there's a good percentage of users how who don't frequent this forum. I have absolutely no idea how @johnbur's property defies the laws of physics but I wish mine would 😩
I'm hoping the new owners of Tado will get to hear about these issues and actually do something about it, but I'm not holding my breath. If past experience counts for anything, I don't think anyone with any clout even bothers to monitor these forums.
Tado uses according to iFixit for their Smart Radiator Thermostat v3+ a Texas Instrument CC110L IC transceiver which TI descibes as a “Value line Sub-1 GHz wireless transceiver” and “The CC110L is a cost optimized sub-1 GHz RF transceiver for the 300–348 MHz, 387–464 MHz, and 779–928 MHz frequency bands”.
TI also sells high- and ultra-high performance transceivers which have a better sensitivity. I guess you get what you pay for, the same as using for the Internet Bridge a 10Mbit/s half-duplex ethernet, and also here the CC110L IC transceiver.
Cheap transceivers combined with very small antennas results in a diminished range. Tado can do nothing to overcome existing hardware constraints. Only a hardware redesign and using i.e. a thread mesh will solve this.
@MichielTado I did wonder if they were using a mesh system, that would have helped if TRV's close by could pass on the signals 😩
@DRH no, that would not have helped. Even a tread enabled battery powered device does not relay the signal. They are thread endpoints. You need mains powered thread devices to do that i.e. the Eve power socket on thread, or any other brand mains powered thread device which can act as a thread router.
Philips Hue, which uses ZigBee, can form a mesh because their lights are always mains powered even when switched off.
