Why is Tado overheating?

Room temp is 22.7°, target temp is 22.2°, yet Tado still turns the boiler on often. Why?

(First day of Tado, simple setup with room thermostat only)

    @Muesli Half a degree doesn't seem at all unusual. Does it move an higher than that?

  • Mine goes to 22.7 when it's set to 21...

    @Mansell Does it stay that far out or go to 22.7 and then flatten out?

    @samd it goes down to the required temperature. Until it starts heating again he over shoots again. The wierd thing is that one day its goes good temperature wise and an other day he overshoot like crazy...

    Can you upload pictures here?

    @Mansell I've seen images on here - try copy and paste?

    I am not sure if this April 2019 post by support is still extant but it may help understand these issues.

    Hi,

    I think there are a few misunderstandings that I wish to address here.

    1. The devices are not constantly in communication, they only report in every 20-40 minutes unless something special happens (e.g. Open Window Detection)
    2. As such, if a device has its batteries removed, the system will assume it is still online until +/- 30 minutes go by without the thermostat reporting in, even if a device is polled for temperature information (for example) and it doesn't respond immediately.
    3. We are looking into changing this behaviour to give a more accurate representation of the actual state.
    4. The calibration is only triggered once after a reset (e.g. removing/replacing the batteries). If the Smart Radiator Thermostat is removed from the mounting-bracket, it will not (at this stage) report as unmounted or re-trigger the calibration. Again, this is something which we are looking into.

    Best regards,

    Frank

  • I swapped batteries and reset the button for three seconds. The thermostat is showing a spanner symbol. App says it has connected to the server but above continue installation it says device not mounted in red?

  • Mine over heats too. Today the room hit the desired temperature, and an hour and a half later it's still heating.

    About an hour after hitting target temperature it dropped from three flames to two in the graig, but kept heating away. Still hasn't stopped after 90 mins, though its just dropped to one flame. It's not half a degree over, but that's 90 mins of heating it didn't need to use.
