I’m just migrating from OpenZwave to ZWave JS. I’m using the ZwaveJS2Mqtt add on so that I have a control panel.
I have 2 FGR-222 Fibaro Roller Shutters and both worked with the previous OpenZwave install in this one - one has detected properly and includes a cover.* entity ID but the other one hasn’t created the cover.
So there is a bug where my module was reporting unknown and HA expected a number - that is going to be fixed in a later release. Also the bug can mean it stops the whole ZWaveJS integration.
However at the moment the best fix was to do a recalibration on the module that was misbehaving - since doing that it hasn’t reported unknown so hasn’t caused an issue
