State of tado Matter support?

We recently saw two new standards for home automation: thread and matter.

I'm going to assume that thread support will have some difficulties. Still, it would be great if we could move away from having a tado bridge and use a general purpose bridge instead. But for the moment, I'm going to assume that's not in the cards.

But what about matter support? I understand that's largely based on Homekit, which tado already supports. So will tado support matter and thus move into a future where we no longer have to depend on vendor-specific home automation systems?

  • They have said they will. Nothing more has been said as far as I’m aware.
  • Matter is based on zigbee and I cannot imagine how the private protocol of Tado could adapt. Fear this will deadly hurt Tado.
  • I very much doubt that tado° will integrate Matter into their current generation of devices......so hold your breath for the next generation of tado°..... whenever that might be.
  • Only the bridge needs to be updated to expose the thermostats as Matter bridged devices.

    Apple already support Matter. Philips already announced that Homekit will be replaced by Matter in 2023.

  • I might be wrong but I thought to be fully matter compliant all devices had to support it, effectively removing the need for a bridge.
  • Thread is the recommended solution. The bridge solution is defined in Matter specification. Zigbee devices are the easier because Matter reuse the ZigBee clusters.
  • Actually Thread uses 6LoWPAN to allow IP communication over low power radio and IEEE 802.15.4 as the low power mesh radio standard. Zigbee also uses IEEE 802.15.4, but it has its own software layer on top of that.

    I understand that Tado also uses 6LoWPAN, but on a different frequency than Thread or Zigbee.

    So in theory the Tado bridge could be turned into a Thread border router and the whole thing could run over Matter. But that requires quite some changes just to make everything that works today work with the new system.

    A simpler approach would be to add Matter support to the Tado bridge, similar how Hue is adding Matter support to the Hue bridge.

    My understanding is Thread can be enabled for existing Tado devices - from this article https://www.the-ambient.com/guides/what-is-thread-smart-home-2410 … “as long as devices support the 802.15.4 protocol then they can be upgraded to support Thread.”

    If Tado will remains to be seen. 

    What’s so disappointing is Tado have had all the technology pieces of the puzzle in place … 6LoWPAN, 802.15.4, etc … for many years now as evidenced by this article https://e2e.ti.com/blogs_/b/process/posts/effortless-energy-savings-with-the-tado-smart-thermostat

    They should have been ideally placed to be one step ahead and spearhead Matter and Thread support. But this clearly hasn’t happened.

    802.15.4 allows 3 main radio frequencies. 2.4Ghz is the worldwide permissible frequency and I suspect all the current border routers (Apple TV, HomePod mini, Nest hub, Eero router, Echo 4 etc) use 2.4Ghz as they also have that radio for WiFi. 868Mhz is a permissible frequency in Europe for 802.15.4. tado use 868Mhz. Unless the aforementioned routers have an 868Mhz capable radio or tado has 2.4Ghz support (which I do not think their devices have as a TRV teardown on iFixit shows they use the TI-CC110L sub-1Ghz transceiver chip) then there is no way for the end devices (TRVs, thermostat's etc) to communicate with those other border routers except via tado's own bridge - which really invalidates thread support. Indeed if Thread certification (distinct form 802.15.4 compliance) requires a 2.4Ghz radio then tado devices can't become Thread devices. tado can still support Matter bridging and expose the end devices over Matter but given they currently support HomeKit, Alexa and Googe Home anyway it might not provide any greater utility for the end user.
