I have two Steinel IS 140-2 Z-wave motion sensors in my shed and driveway. The issue I have that after a few months, Homey doesn’t show any updates anymore. This now happend 3 or 4 times. They still switch lights whenever the motion sensor is triggered (a directly connected light via the Steinel, not via Homey). Also, I can send commands from the Homey to the Steinel, for example I can switch the connected light on and off. I just don’t see updates that the motion sensor is triggered, so either the Steinel don’t send status updates anymore, or the Homey stops processing them.
So far, I tried to either turned off the main power, that worked a few times. This time, I tried to unpair and pair the devices with the Homey. Unpairing (remove device from the Homey) worked immediately. Pairing requires a bit of clumsy process setting a potmeter on the sensor to max and then to minimum within a few seconds. I had troubles getting that to work with one motion sensor, but after 10-20 attempts, I succeeded. However, for the other motion sensor I can’t get it to work. The motion sensor does blink. The homey goes into
REMOVE_NODE_STATUS_LEARN_READY when I look in the Z-wave debug logs. I placed the Homey in direct range (outside in the driveway, about 4 meters away in plain sight, as close I can get). Despite that, there is no sign of pairing.
I’m a bit stumped why this is so troublesome, and how I can debug. Is the Steinel broken? Is the app unstable? Is the Z-wave signal too weak? Am I too impatient?
Any suggestion to move forward is appreciated. What would you do? Give up? Try to debug Z-wave? Buy a new motion sensor?
It’s not the end of the world – I deliberately bought 230V motion sensors with a directly attached light so even if Homey is down, the lights just continue to work, and they do. However, what fails is some smarter flows, like a different light going on when I approach the driveway.
