Inaccurate temperature readings

edcldn

Good morning

My Tado TRVs and the main Smart Thermostat consistently over-estimate the temperature.

The TRVs are miles out. I placed another small thermometer right next to the TRV, so that it was measuring the same location and the TRV measured two or three degrees warmer than the non-Tado thermometer.

My Smart Thermostat consistently records about one degree warmer than an independent thermometer.

At the moment I am trying to address this by asking Tado to heat to a higher temperature.

Is there a better solution than this? Are my Tado thermostats unusually inaccurate or is this a general issue?

@edcldn Hello. Yes a common issue but more about the tado TRV rather than the Room Thermostats. There are a number of threads on here and, particularly a thread asking tado to develop a cheap external thermostat to use as measuring device for the radiators. You may wish to add your voice there.

There is a setting where you can adjust the temperature either way +/- so for example if its reporting 20 degrees and its actually only 18, you can set it to -2

Thanks. You might hope that a “smart” thermostat producer might value accuracy...

I installed two stats last week and while I'm still figuring out the finer details if schedules etc I still cannot get over how such an expensive stat cannot read temp or humidity correctly. Both I have installed are reading 1.3 degrees and 2 degrees over the actual room temp which I took with a laboratory temp monitor in exactly the same location.
Really disappointing that the main function or reading temp is so far out. Both are also between 15/20% out reading room humidity. I have stuck the two old Siemens/non brand stats up beside and both read correct temp in the same location

It's because the trvs are so close to the heat source so they are accurate in reality there trv should come with a small device included that you put in the room to get to desired tempature

There are no tado TRVs on my system yet and I doubt I will bother paying for them when the readings are so inaccurate. Just standard danfoss. It is a wall mounted tado stat. Is this day and age a €2 temp sensor from AliExpress can give a more accurate reading than Tado. Again I can't understand how this product gets past QC with readings like this

You're lucky it's only 1-2 degrees out. In my bedroom the thermostat is regularly reading +8 degrees compared to the baby temp monitor I've purchased. Really irritating as I have to bump the temp up by over 8 degrees to compensate and even then still isn't enough. Assume it's because the trv is next to radiator, but this is obvious design flaw so needs a remedy.

My (wall mounted) smart thermostat reads a couple of degrees above a sensor I have in the same room. You can overlay the graphs and they match very well.

My experience of Tado TRVs temperatures is very bad and wild not fit for purpose I ended up using an external Room Thermostats rather than TRV. These Room Thermostats are well overpriced!
