Sorry for my late reply and thank you very much for your help.
Your answers helped me to get the device working. Now it works perfectly.
With the following steps I could achieve this:
- In order to change the configuration parameter of the device I installed HABmin - see Help to install HABmin - a graphical user interface for openHAB 2
- The manual of the sensor is really good and as @sihui said, configuration 7 Bit 4 needs to be changed. In HABmin under Configuration > Things > Z-Wave Node X> PST02A Slim Multi-Sensor > Configuration Parameters > 7: Customer Function
- The default Value of “7: Customer Function” was 4 and needs to be changed to 20. Here is the explanation:
- The default value 4 means that bit 2 is set (counting bits starts with 0 therefore the binary code of 4 is
100) - Therefore setting bit 4 to 1 requires a binary value of
10100and this value converted to the decimal results in a value of 20 - To convert between binary and decimal under Linux execute the following in the terminal:
- from decimal to binary:
echo 'obase=2;20' | bc - from binary to decimal:
echo 'ibase=2;10100' | bc
- from decimal to binary:
- The default value 4 means that bit 2 is set (counting bits starts with 0 therefore the binary code of 4 is
- After changing the configuration I had the problem that the parameter was not sent to the device as battery devices sleep most of the time to save battery. In order to wake up the sensor you need to press the tamper key on the back side of the device. After pressing the tamper key the new configuration setting was set correctly and the device started to work as expected…
