Fibaro FGMS-001-PLUS, Motion Sensor (already added error)


Is there a way to see and remove a device that is being reported as ‘already_installed’ when you try to add it but it doesn’t show on your list?

I purchased 2 x FGMS-001-PLUS, Motion Sensor (Z-Wave Plus) devices, first one added fine with the Fibaro App but the second one keeps reporting that it is already added. They do get a unique identifier each, I may hope?!


A zwave device can only be coupled to 1 controller at a time, so if the device already thinks it is included to a controller it gives that message.
The only way to fix that is by resetting that device,
by either factory reset of the device itself. (see manual)
Or removing (which also resets) it via homey in settings -> zwave -> remove device


I actually just managed to find it. The developer webpage allows you to remove any node and I was able to run that succesfully on the sensor by using the pairing action (tripple click button). It reported to have removed an unknown node and tgen I could add it succesfully!


I could not remove it from the device pane as it was not listed there.

I never said to remove it from the device panel, as a device could also be included into another controller it has a very big chance not being in homey.

A good practice for zwave devices is to always reset the device to factory, even if it is brand new.

And as already said there are multiple options to reset the device, 2 I told you, the 3th one you found yourself.

Then of course follow the instructions on your screen, not just wait as that won’t delete anything.
how should homey know which device it would need to delete (/reset) so you need to let homey know by activating the removal/inclusion procedure of the device.


Thanks, your solution is easier than mine indeed.
