I'm in this camp as well. I've had one motion sensor of theirs since June that supplemented an IKEA one to catch movement at a different part of my hallway and had no real problems with it. I ordered another couple recently as well and put one in my kitchen and another in my office.
I might have been seeing odd behaviour on my office one but I've not had time to investigate it though and I was more inclined to believe it was bad positioning than a faulty sensor.
I did notice though that if I enter the room just as the lights are turning off then the lights don't turn back on but I just go straight to the light switch and do a quick turn off and back on again job to fix it.
I chose to take down my production instance of lemmyz do a cp -r of it, update the docker compose file to specify the new version numbers for Lemmy and lemmy-ui plus change the port that the stack exposes and do a docker-compose pull && docker-compose up -d on that stack to check to see if it could all work. Thankfully it did, so I updated the production compose file and tada! I'm on 19.0 safely
