Yesterday evening I installed a new z-wave switch (Fibaro FGS223) together with a motion detector (Aeotec Multisensory 6) in my laundry room to automate the lights. Apart from some fiddling to get the wires connected the right way (two switches in a multi way configuration) everything went smooth.
Then comes the motion sensor. I got it included in the network, tweaked the configuration parameters and set connected it to the switch via association groups. Then I tested it by entering the room. Instead of just turning on the light, it started blinking. On - off - on - off… Went back to my computer and removed the association, but the blinking continued. After a minute or so the blinking spread to all my other Fibaro switches, in the kitchen, the living room and the outdoor light.
I got a bit of a panic an ran around the house, pressing all switches, Wich turned off the blinking, but the neighbours must think I’m crazy by now.
Turns out the motion sensor use the alarm command class to indicate motion, and Fibaro switches, by default, react to all alarms by blinking for 10 minutes. Now I have set them all to ignore all alarms.
Don’t make installations like these when it’s dark outside, mistakes might visible by the whole neighbourhood.
