Since the last beta update the option to select USB at the serial menu is gone. only the option serial1 and AMAO can be selected.
Does anybody know to solution how i can restore it?
This is causing that the smart meter readings are not read.

Hi @rubelke,

On which device are you running? And what is your OS?

Regards

I run it on a rasberry pi.
Version 10
Buster

Hello @rubelke,

I use the same hardware and software. I use the same Domiticz version 13689 and doesn't notice any problem. Did you clear the cache?

See: https://www.domoticz.com/wiki/Troubleshooting

Hello @firewizard,

Yes i did, but it did not help.
I'm still missing the option USB in the pulldown menu.

Hello @rubelko,

Could you check, and if not found, carry out the commands, as described at: https://www.domoticz.com/wiki/PersistentUSBDevices.

In my case I have the following contents in:
The 1st line indicates the P1 Smart Meter, while the 2nd line indicates the RFX 433E.

Let me know.

Regards

Hello Firewizard,

I used
_{sudo nano /etc/udev/rules.d/99-usb-serial.rules}

And my file was empty, i dont know if that is correct because there is only one usb device connected and that is the P1 cable.
Should that be visible in the rules file?
Can it be possible that the cable is broken and that is causing that the device not is visible.
Is the USB option in domoticz only available when the usb device is detected?

Simpel unplug and plug in the P1 USB cable.
do a and look at the end of the output if your P1 is detected.

I get the following output file.
Looks to me that the USB device is recognnised but in domoticz not?

This looks to me a part of dmesg from 14 till 20 seconds after boot.
After the boot you should pull and insert the P1 USB plug, then you know for sure which USB port you have connected to P1.
B.t.w. it does not look good to me, because of the several "error -32" and that might be a power issue.
