[Released] Launch an external temperature sensor for the Smart Radiator Thermostats



  • All we need is to be able to use any external sensor through Smartthings for example.... I have 5 multipurpose sensors on windows, and a PIR sensor, all which have temperature sensors built in (btw I find those expensive at 25€ each, and that's still 70% cheaper than the ridiculous Tado sensor). So I have 6 temperature sensors around my house, plus 7 Tado TRVs, total 13 temperature sensors around my house, that cannot be used to control temperature because Tado decides they want to screw their current customers by not allowing 3rd party integration (Smartthings, hubitat, home assistant), and charge 80 euro for a stupid temperature sensor you already have around... They are using the same strategy as Apple. "It works, but just if you use our stuff, for 3x the price it should cost", except their "ecosystem" is not an ecosystem, is just a couple TRVs and an overpriced sensor, that can't be integrated with anything...

    If you have vertical TRV's have a look at this thread for getting accurate TRV readings without buying the overpriced sensor.


    I have brought some and can confirm a vast improvement in temp accuracy.

  • I been snooping around, there is at least one other brand that delivers the same. That is Comap, base price is about the same. Danfoss indeed delivers and angled one, from M30 to Danfoss, that would require an adapter, but could be price efficient.

    +1 Give us a simple and cheap temperature sensor. Not one with fancy temperature settings, just a simple one (one AAA or AA battery). I don't want my kids to fiddle with the temperature settings, which is inevitable on the current (and expensive!) temp sensor.
  • It say released at this topic. What is released? I can't find it!

    @alterego The Tado “Wireless Temperature Sensor”: https://www.tado.com/gb-en/wireless-temperature-sensor-overview
  • Ok thanks. I was hoping for a < 50 euro solution. It's 70 now.

  • I was trying to upvote this proposal, but seems to be closed. Why I cannot upvote it?
  • @RamonCar Because Tado's solution has been to launch the Tado “Wireless Temperature Sensor”: https://www.tado.com/gb-en/wireless-temperature-sensor-overview

  • After the overwhelming call for a smaller, cheaper Wireless Temperature Sensor, I have opened a request here: https://tado.vanillacommunities.com/en-gb/discussion/8235/release-a-smaller-cheaper-wireless-temperature-sensor-for-the-smart-radiator-thermostats/

    If you'd like to see Tado do this, go ahead and vote!

  • Thanks, @jcwacky , done!
    If you agree I will share this link in the spanish tado forum for users to concentrate on one thread. I think we're not
    so takenn into account.
  • @RamonCar Of course! I wasn’t even aware there was a Spanish forum!
  • @jcwacky Thanks for opening a new topic on releasing a cheaper version of the temperature sensor. I am not making any promises other than this feedback is noted and passed on to our development team.

  • 100% in agreement that Tado° must release an INEXPENSIVE remote temperature sensor. The current €80 "solution" is a sick money grab :-(

  • I'm very happy with Tado overall

    What are you happy with?

    For me, I only have radiators, and this product is a complete failure.

    The *only thing* this product really needs to do is adjust a valve based on temperature readings. But the temperature readings are way off, so the product cannot function.

    But I would need to pay 100 euro each for a temperature sensor for each room. So that 180 euros per room.

    Philips Hue offer a temperature/light sensor for 30 euros.

    What are you happy with?

    My original starter kit also had the Smart Thermostat in it, so in this room, coupled with the SRTs I was very happy with how it all worked, plus the app etc.

    If you only have SRTs then I can understand why you aren't happy.

    Since, I posted this original request I no longer use any (mounted) SRTs as temperature sensors. I bought a couple of 2nd hand Smart Thermostats on eBay, I use unmounted SRTs as temperature sensors in a couple of rooms, and have set rooms like bathrooms to passive (e.g. independent mode).

    So I'm now very happy with my whole setup. But still disappointed that Tado still doesn't offer an affordable wireless temperature sensor for the SRTs.

    I use these adapters to off set the tado trvs from the radiator. I find this solves to inaccurate temperature reading and now my system works really well.

    Check eBay and Amazon of you want to try one.
  • I bought three Tado temp sensors for 50 euro each which is reasonable. Had to go Black Friday plus energy company subsidy. This fixed three of my rooms.

    But I have 6 rooms and it seems excessive.

    My apartment entrance is currently at 23 degrees, but its actually 18.

    @RichF Thanks for the tip! I will try that out.
