after every restart of my raspberry pi (using openhabian setup) the ZWave communication does not work anymore. I get error in the logs and the zwave devices do not receive commands.
Every time after a restart I have to do the following procedure to get the ZWave communication work again:
Plug off the ZWave dongle
Restart Pi and wait until booting is complete
Plug On ZWave dongle again
Find serial port with dmesg (which did not change to the last working set-up), meaning this step is not necessary
enter Serial port in OpenHab
et voila, it works again
Do anyone know this behavior or could tell me what to do to avoid this? many thanks!
Well, there are much more things like this in OH where you might ask this question. The basic answer is that it is a open source development with volunteers working on it. At the moment you will find a lot of such examples.
Plug your ZWave dongle into your raspberry pi and check the port of ZWave dongle this time => port X
Then, restart Pi with your ZWave dongle still plug into Pi. Check the port of ZWave dongle after restart => port Y
If port X difference port Y, the ZWave communication will not work anymore.
I had similar problem and these steps above are the way to debug this problem.
