They are ok to a certain degree! hard to get setup and hard to make changes after you set it up but for me needing then for medical reasons its worth getting them setup though how frustrating it can get to do so. You just have to be very patient to do it and don't expect that in a day, took me 6 months 🙂 but got it to a pritty good for me but not perfect. I think your setup should be a lot easier with no Zones as its them that are hard to keep changing if needed too. I want to as some point move my bed and if I do then the sensors woudl all need to be re setup again for the changes, Its not a easy process and hope it will get better and easier in time, which I'm sure it will. It also detects me when I'm sat on my chair to turn on certain leds and turn off if I'm not say on the chair! SO on that Id say yes its worth getting one, in my case I have 4 but the two on the stairs was easier for some reason to setup not sure what I did different but got them up a lot quicker and sensors go off when I'm in certain places though I never had any zone detections setup for them so I no clue how it managed to do it but happy it does it!
