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 :-(
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.
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 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.
Its 31/01/2023 I have just bought some Tado TRV's and not happy with them after reading this post looks like tado external temp sensor is now £89.99 too expensive. I don't think there is any alternative solution? so I will be returning my TRV's and Tado system for full refund as this is not fit for purpose.
An "External Temperature Sensor" is a sensor that is attached to an outside north facing wall and is used for true Weather Compensation.........you have quoted a tado° (indoor) Wireless Temperature Sensor........
@GrayDav4276 In the context of this topic (look at the title), I think we all know what @Jacopo2 was referencing. It's external to the Smart Radiator Thermostat.
And yes, @Jacopo2, they are still too expensive!
@jcwacky & @Jacopo2
My fault for not realising that this thread was never about an "External Temperature Sensor" and was actually about a Temperature Sensor as an additional device to be used in conjunction with a SRT..........I should have read your ( @jcwacky ) original post title better and would have therefore realised the point(s) being made.......my bad 👎
But if it helps.......I agree with both your comments( @jcwacky & @Jacopo2 )
Now having said all that.......as I am very likely to be removing my tado devices after this current Winter period......I think that I'll probably scale back my comments in this Forum.......after all...... most of my 1.7k comments made have fallen on tado°s deaf ears.
So.....apologies for missing your point........
There is a FREE/NO money costing work around for this.
What i suggest you to do:
1 Set your room temp at max
2 Measure your room temp with an external thermometer
3 Once your room temperature reaches your desired temperature (displayed on ext. thermometer)go to your tado room settings and read out temp for your room.
4 There will be an offset between tado readout and thermometer readout, use this offset to set up your room temp planning
5 do this for every room
Yes, 21C° room temp will not be exactly 21C°, but feeling warm/cold is a feeling not exact science, so a degree/half degree more or less is in my opinion not an issue.
Just understand you'll have to work with an offset. It'll give you some headaches in the beginning but trust me after a while you'll get used to used to it.
