By design, Homebridge deCONZ exposes a hidden dummy motion sensor so Eve shows the history for Light Level. I think Home ignores the hidden setting. Eve honours it, but still shows the dummy motion sensor in the Types view.

[ghost]

That was not the case with homebridge-deconz v0.1.0 and I have never had a motion sensor in HomeKit

[ebaauw]

Homebridge deCONZ is still under development; new features are added with each version.

[ghost]

But why expose a motion sensor when it is not present. It's going to be a mess in HomeKit

[ebaauw]

See above: so Eve shows the history for Light Level.

The mess is more Apple's Home app than HomeKit. As I said: Home ignores the fact the the motion sensor is hidden. It also shows Humidity in rooms with a (native HomeKit certified!) Eve Thermo thermostat, through they don't carry a Humidity Sensor.
