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.
It say released at this topic. What is released? I can't find it!
Ok thanks. I was hoping for a < 50 euro solution. It's 70 now.
@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!
@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.
Just came across this so thought I would post a comment to say I have been working on this too. Spammed in a few places, hoping it helps
I use Home Assistant so have targeted that as a solution and did a PR to PyTado and to HA Tado integration. So now the offset can be updated via automations in Home Assistant and I wrote an automation for it as a kind of template for anyone using Home Assistant to copy and paste, which manages all devices in the house (including a battery saver option).
My Home Assistant automation write up is here: https://github.com/north3221/home-assistant-config
It was discussed on Home Assistant here: https://community.home-assistant.io/t/tado-integration-put-offset/175964
and here: https://community.home-assistant.io/t/battery-level-and-temperature-offset-for-tado/81068
If you are not using Home Assistant, you could still take advantage of the PyTado library: https://github.com/wmalgadey/PyTado
I use the aqara temp sensors, which I got for about £8 each on Aliexpress, but you can get any temp sensor you want that works with HA
100% in agreement that Tado° must release an INEXPENSIVE remote temperature sensor. The current €80 "solution" is a sick money grab :-(
