Weird sensor values (xiaomi temperature sensor) / conbee stick

recently i noticed some strange values, coming from a xiaomi temperature sensor (-100 degrees celsius) connected to the conbee zigbee stick. I assume that these values showed up after an update of the conbee stick.

i have multiple of these xiaomi sensors connected to this conbee stick, and this is the only one that shows these values of -100 degrees celsius. The other sensors are doing fine. i did some research, but i can’t find something similar in other topics.

What i recently have done is changing the battery, but the values of -100 degrees didn’t dissapear. Strange right?

Have similar experience with Aqara sensor, connected through ConbeeII stick and deCONZ. Replaced sensor but after a while same -100 values.

You found a solution? Maybe convert the -100 to some unknown value. Now the graph is completely useless.
