I figured I spent enough time debugging (see my posts earlier in this topic) so I decided to buy a new cable, this time not one off Ebay but a P1 converter cable v2 from smartmeterdashboard.nl (avoiding any issues in the RS232 to USB connection). It was a bit more expensive but everything works now ...

Thanks bbqkees, I figured I was the only one since I haven't seen any other posts about this. I thought my cable was ok based on the readings under Windows so that's why I didn't buy a new cable. But maybe that was the wrong conclusion so I'll just buy a new cable. I did spend a few evenings on this ...

Hi, I originally posted an issue with reading my P1 meter in domoticz.com/forum/viewtopic.php?f=14&t=4970. That was a while ago (June last year) but I wasn’t able to solve the problem back then. I hadn’t had a chance to look at it again until last week but I think I’ve come a bit closer to the solut ...

Btw, I had a quick look at the domoticz code and it seems that baud rate 9600 implies 7 bits character size so that's not where the problem is...

ThinkPad, thanks a lot for your quick responses! The other topic is indeed very similar. I'll look into whether the settings for the reading of P1 can be set manually in domoticz. From gizmocuz' reponse I infer that domoticz should set the correct values automatically but maybe it doesn't work for ...

I connected it to domoticz but it's not really working. I added the hardware and set the Baud rate to 9600. It shows up in devices and when I check the log I see an entry from the smart meter every 10 seconds. If I check the Data in devices it's 0;0;0;0;0;0 however. It's been running for about 10 ...

Thanks! 115200 didn't work but I tried playing around with the other settings and when I set Data bits to 7 (instead of 8) I got sensible data at Baud rate 9600 (see attachment). So I guess the cable is fine. I'll connect it to domoticz again and see if it works now.

Hi, I am trying something similar as described in this topic and I am having some problems getting it to work. My smart meter is a Kamstrup 382JxC and I am using a HL-340 USB to RS232 Serial Port Adapter Cable (from dx.com) to connect the smart meter to a pc running domoticz (on linux). As I wasn't ...
