Newbie: State not changed when z-wave sensors are triggered

  • Platform information:
    • Hardware: RPi 3
    • OS: OpenHABian 1,4
    • Java Runtime Environment: 1.8.0_152
    • openHAB 2.2.0

I have set up a few z-wave sensors with an Aeotec Z-wave USB stick on a Raspberry Pi. I can see all the sensors and the ones that have temperature sensors built in report the correct temperature, but when I trigger the sensors (stick the flood sensor in water or move the magnet towards the door sensor), nothing happens. Sometimes, when I trigger a sensor, a “Thing ‘zwave:device:16fb98ad:node4’ has been updated.” line will appear in /var/log/openhab/events.log, but most of the time, I get nothing.

I had been playing around with Domoticz on my linux box and there I got events immediately when I touched a sensor, so I moved the USB stick to a new Raspberry Pi, installed OpenHABian and configured the things and linked them with items in the Paper UI.

How would I go about debugging this?

  1. Please make sure that the z-wave sensor inclusion is finished. The better way to check is to go to HABmin. Go to things, check if there’s any message saying “initialization…” under z-wave node.
  2. Openhab use console Karaf for debug. the command is log:set DEBUG org.openhab.binding.zwave.
