Fixing Node's Group (stuck on broadcast, 255)

Somehow my Aeotech Mutlisensor 6 got stuck with node id 255 in its zwave group so when it senses motion it turns on EVERY light and switch, then when it stops detecting motion it turns off EVERYTHING. It’s really annoying and the new Z-Wave manager does not seem capable of removing node id 255 from its group.

Is there a way to fix this short of doing a factory reset on the multisensor? I would like to think that if I had OZWCP still available I could fix it, but that seems to be gone…

I don’t know about your specific issue, but I just made a Hass.io plugin for OZWCP, so you can haz that again if you want. New Add-on: Open ZWave Control Panel (OZWCP)
