Domoticz

As mentioned before check with
ls /dev/serial/by-id

Also in the P1 hardware configuration you should see the by-id entries in the pulldown list in the serial port field.

i finally got the by-id working, but it still won't receive any data, I will contact the Electric Company to let them check the meter is working 100%, I have my doubts it is sending telegrams through the P1, next thing is to buy another P1 cable too see if that changes anything, probably will buy a P1 ethernet thingy so i can access it through LAN

Hi,

Are you sure that the Baudrate is only 9600 Bd.
This is only the case if your P1 Smartmeter uses DSMR protocol 2.2,
which is rather old. What is your meter brand/type?

Regards

yes i am sure, it was always on 9600

it's a Kamstrup 162JxC, it's over 10yrs old for sure

Hi @balosa

Did you check the USB port to which the P1 Smart meter cable has been connected?
If you found the correct USB port, did you check the RAW protocol?

Stop Domoticz and execute the following command in case the port is USB0. If otherwise replace the number.
What do you see?
Let us know.

Regards

Hi,

Sorry for the late response, it just says it is connected.
After that it hangs, I have to restart Putty to enter commands again
.

Well there is a breakthrough, the problem was the electricity meter from the power company, it didn't send anymore data through the P1 and to the company itself, the meter has been replaced and now I'm getting data again.

Thanks to all who did try to help and for the advice given !
