Why do I get different humidity value in the tado app and in HomeKit?

I have a tado smart thermostat, it is turned off now. Currently in the app I see 58% humidity but in HomeKit only 54%. The temperature looks like to be correct.

    @Ursus Hi - Cannot help you over Homekit but I can say that the tado smart thermostats I have are within 0.5 of a percentage point when measured against recently calibrated equipment.

    I have no problem with the measured value, the problem is that I get a totally different value in the 2 apps. I assume tado is not updating it too often in direction of HomeKit, the humidity value, temperature is fine.

    Hi I’m having the same issue.
    Did you ever get this rectified ?

    Common issue recently, no official statement as of yet :/

    Maybe the issue isn't that the values are incorrect but that the HomeKit values are not updated as often (edit: I just realised that the OP already made this assumption too). I am running both the API plugin and the HomeKit in parallel on Homeassistant and I am seeing far less updates on the HomeKit integration than using the API. Sometimes updates are 8+ hours apart. The official documentation states that humidity is updated at least every 15 minutes or if the humidity changes by at least 5% since the last update. This does not seem to be the case with the HomeKit integration which is really annoying as it makes the humidity value unusable when using HomeKit.

    Is there anyone from Tado able to confirm what I am seeing?

    @vinsie did you ever resolve this or find out anymore info?

    In fact the homekit API refresh the humitidy values only if they change more than 5%. There is no refresh every 15min. I already reported this bug to Tado.

    I use the humidity value to dry to drive the bathroom dryer. This 5% of error makes the thresholds difficult to find.

    Tado is incredibly unstable lately, so I've been controlling my thermostat through HomeKit. Everything works flawlessly - asides from my data collection. Temperature updates regularly, but humidity doesn't. For now, I'm just using the Tado Cloud for my data collection, and HomeKit for local control.

    Still a persistent issue ( bridge model IB01, FW 92.1 )

    Confirm. Same exact issue. Firmware 92.1. It updates only if humidity change reaches 5%. That makes my Home Assistant sensor stale.
    A 15 min regular update would be ok for humidity control.
