Aeotec Multisensor 6 gaining sentience

I’ve got a half-dozen of these things deployed. The other day I noticed that PM2.5 had been added to one’s sensor list. Today, many more sensors have been added. Are any of these viable? Why is this happening?

Particulate Matter 2.5
Radon Concentration
Distance
Electrical Resistivity
Frequency
Soil Temperature
Loudness
Barometric Pressure
Solar Radiation
Water Acidity
Atmospheric Pressure
Angle Position
Rain Rate
Seismic Magnitude
Velocity
Rotation
Air Flow
Current
Weight

Yes, it’s a known problem/bug/feature

Apparently a year later still a thing. Is it a bug of Aeotec’s firmware or something in HomeAssistant?

I am very surprised that my sensor now shows Radon concentration, lol

It’s Z-Wave related - you may not see that on the new Z-Wave JS integration

Now that you mention it, I don’t see it on Z-Wave JS.
