Smartmeter binding stopped working and cannot get it running any more

Hi, im using the newest Version of openhab 3.4.1 and my problem is on smartmeter binding.

what happened:

  • i have read my smartmeter for some years by an optical adapter which is connected to serial on raspberry and yesterday i got a new one Elster AS3000.
  • i changed meter was changed and some hours i was able to read 1.8.0 and others more as old meter before
  • new meter has ability to rerad more values and so i added them
  • after that it was no more possible whatever i did (restart openhab,reboot raspi, configtrys, bufferfash by pythonscript and so on to get it running

The problem it shows in log (only some lines):

if im trying to make a cat on device then im getting values which seemed to make sence:

cat /dev/ttyAMA0 
0-00,00:00,00-00-00,00:00)
C.71*06(00-00-00,00:00,23-01-19,13:44)
C.71*02(20-04-29,08:23,20-10-16,11:41)
C.71*03(00-00-00,00:00,00-00-00,00:00)

So i restored config as before which i had from screenshot. But it was no more able to restore the behavior that i can read out it.

configscreenshot which was on before all tries and also after:

Because i have no more idea what i can do i hope someone can help me.

Best regards

OK, it seems to be resolved. Halve an hour before the person from powercompany was here and he had problems to see data from meter.
So we resetted the meter by power on reset and after that we were both happy. They can read the meter again and also i can read it. Seems the communication-module of meter itself was the problem.

Hope it will not happen again…

Best regards
