Jablotron100 connection failed – all sensors and devices are unavailable

[Tomm206]

Hello,

I have a problem with connection of my Jablotron100 integration (since 24-08-22). All sensors and devices are unavailable. It always happens once or twice a day. Restart of HA usually doesn’t help.

See the log below:

`This error originated from a custom integration.

I think the port is probably changing.

[Tomm206]

I did not change the usb port. I originally installed on "hidraw0". My Terminal & SSH shows:

I am little bit confused. Any advise please? Jablotron intergration is key integration for me. Many automations rely on Jablotron integration. Thank you.

[kukulich]

Your operating system may change the port.

[Tomm206]

Operation system may have changed it. Then I dont understand why it works half a day and then it doesnt. Terminal & SSH shows "hidraw0" and "hidraw1". So I dont know which one is correct. I can try to change it in integration. Could you please advise me how to change it? Thank you.

[Tomm206]

Today the integration worked till 12:30 pm (from night restart). Then again all unavailable. Any idea please?

Can I just try to change the port here? /config/custom_components/jablotron100/const.py

DEFAULT_SERIAL_PORT: Final = "/dev/hidraw0"

from hidraw0 to hidraw1?

Thank you.

How did you solve it? The link doesnt work. Thank you.

HI, same problem here, how do I change port name on OS layer? I am also not able change port in integration, I can fill port only when I install new integration.
