Hi,
I migrated from openHAB a couple of years ago, and have a few posts up discussing tips on the journey.
ISTR there were issues with the Gen7 chipset, but also remember reading all was fixed.
I moved tens of Fibaro Z-Wave devices across with a Gen5 Aeotec stick, and whilst some worked, factory resetting a few was needed to get them to reappear on the same coordinator, with the same S0 and same hardware. (My Gen5 is a hacked version with a hardware fix for the stupid USB design mistake that can fail with RPi4.)
The PITA with Fibaro kit (apart from NO FIRMWARE) is the small plastic button on the case and rubbish internal reset switch. A few FGD-212 needed a plastic probe (as the internal circuitry is referenced to mains voltage) to go through the colour sequence and reset/ pair.
My kit just repaired with HA and worked, so apart from not seeing enough router notes for a decent mesh, don’t know what to suggest.
I’ve not got any roller shutters myself, but have seen others commenting on them - try a forum search?
openHAB wasn’t able to mark a node as failed so a few years ago, but this might work now with HA (not tried it). You do need to remove a “dead” or “reset” mode as the coordinator can sometimes try to reach it - which used to cause 120S time outs on openHAB.
Worse case - try the Aeotec software and a firmware update? My G5 got a lot better back in openHAB days with newer firmware (hmm - seeing ZW090 AEON Labs Firmware: 1.2 so nothing to update potentially).
Generally, I’ve seen significantly longer battery life on Fibaro multi-sensors, and stuff working. Still miss Chris hacking on the protocol stack, even if HA is going for full Z-Wave certification in the near future.
TTFN,
James
