It did on saturday. Then I saw, that a sensor isn’t working any more (airpressure). After fixing my os for other reasons, installing openhabian instead of raspian, it all fell apart.
If there is no change to the firmware or binding which might cause the malfunction, maybe it is the hardware. Linux is recognising the stick in dmesg though… which led me to the conclusion, that the stick might work. But maybe it is recogniseable but not working.
Well, if it worked 2 days ago, and now doesn’t, I guess the first question is if YOU changed anything (eg did you change the firmware or even update the binding)? Nothing has changed for the binding for a while (as I said, the CC2531 driver is basically the same as it was over 1 year ago. I know others are using it, so it should work.
The error message you mention indicates something fundamental is wrong with the communications - either the stick, the serial port, or configuration, but I’m not really sure how to narrow this down further for you unfortunately.
No, I didn’t change the fimrware. I did change the OS of the reaspberry pi as i mentioned. Another major change is the change from OH 2.4 to OH 2.5. Honestly I cant remember wich version of the binding I did use before. I do now use the binding version as mentioned above.
I think as well, the communication is not working. If I plug the stick in, the green indicator lights up, the stick is recognized by the system. After a while the green light stwisches off and there is no communication to the stick anymore.
The relevant users have access to tty an dialout, the obenhab.conf is changed in accordence.
The binding website does mention the firmware needed. What I want to do is to check the firmware installed. If this is the one which is needed, it might be indeed the stick itself. Does anbody know how to check the firmware?
I have not tried the Zigbee binding but I don’t think you need mqtt to use it?
If you plan to use Zigbee2mqtt then you will need to install the mqtt binding in PaperUI under bindings section (not the embedded one in Misc section). Also recommed to use mosquitto broker and you can install it using openhabian-config tool.
