I have bought 3 devices. A measuring accuracy of ± 0.1°C is indicated. I am currently measuring 20.5° / 20.8° / 21.2°. Seems to me to be quite far away from the stated accuracy...

In the official technical sheet it mentions that the temperature accuracy is +- 1 celsius not 0.1. https://pim.beurer.com/images/attribut/DB_HM16_0414.pdf

For some time now, the humidity display has been showing "LL". What does that mean? There is nothing in the manual.

What is the measuring accuracy of the hygrometer? I know from experience that you have to reckon with plus minus 15% (!), so utopian values. What is the measurement accuracy here? Thank you very much.

Hello What does LL mean in the humidity display?

Hello , Is one of these devices enough to get an accurate measurement for a 48m2 flat? Or do you need two? Thank you

Hello Is there any way to delete the minima and maxima?

The description says "868 MHz radio frequency" and I bought this thermometer to read the temperature remotely on this frequency (rfxcom protocol). But it is not detected, and the documentation does not mention this frequency transmission. What about it?

Is the battery included ?

Does the display light up or is it dark? (For use in the bedroom)

Is it possible to reset the min/max values without removing the battery?

Can anyone tell me approximately how long the battery will last? I don't want to have to change the battery every six months.

What are the masses like?

My appliance doesn't waver, I've always had the same reading on the display since the beginning: 22.8 C / 46 % RH? What's going on?

Are batteries included with this device or do they have to be purchased separately?

I just purchased this device. The device is not working- it shows 22 degrees and 46% humidity at all times- even if I set it outdoors. The battery is correctly placed.

Why does it have two display values ?( Min. and Max.) which of the two is the valid one ?

Which display value is the decisive plus or minus.
