Installed latest beta and setup the Uservariable for the gasmeter on channel 2.
Gasmeter shows up fine again.
Thanks for all the help.

@BlueMoon Since version 3.8153 does some more checking on the input, and that's where this issue comes up. So the expected physical changes could perfectly well have been applied way earlier. Thanks. I had dismissed 3.8153 as a possible cause since it had been around since july and the gasmeter ...

@gordonb3 Thanks for your explanation, also earlier in this thread. You already made it very clear that a second (phantom) gas meter on the M bus created this problem. My question was about how this second gas meter could pop up out of nowhere. No physical changes to the 2 meters. Software update ...

@edgar So if you are in the same boat and see an extra gasmeter on a extra channel, you can call your grid operator (in my case Liander) and when describing this problem, say that this is for the smart meter division. The people working there know how to solve this. They do it remotely with a minor ...

@mosjonathan

In beta there is now a option to set a uservariable to select gasmeter channel.

Thanks. I'll keep this in mind, but for now I try to avoid beta's at my friends setup.

Voor Domoticz stable op de RaspberryPi v bij een vriend: sinds 8 september geen gas meter waardes meer. Weet niet of dit met een Domoticz upgrade of een update van de Liander apparatuur komt. De data die via de P1 kabel binnenkont laat 2 gasmeters zien. De meter op kanaal 2 heeft de actuele gasmeter ...

Last night at 00:00 the Gas meter readings started to show up in Domoticz. First reading of course the total use of the last 2 days ;-) Everything seems fine now. Every data-block now has a '0-1:24.2.1' entry with the m^3 value below the '0-1:24.0.1' device type entry. Meter readings took ~36 hours ...

Of course standards exist to be broken, so the fact that the datagram you posted did not contain such a line does not qualify as a conclusion, but it does look like your gas meter is not connected. Had looked into that, but on the Energy meter the correct Gas meter number is displayed, so I assume ...

Ok. Dead end.
Reading the "P1 Companion Standard" I understand my Gas meter is on channel 1 to the Smart meter.
So a Gas use value should look like "0-1:24.2.1(xxxxx...) ?
So far haven't seen such a code in Putty when looking at my PI with 'cat /dev/ttyUSB0'

but AFAIK if a gas meter is connected its data should be in every datagram. Doing some troubleshooting: Rate limit for the Smart meter hardware set to 180 secs. In the Log now every second data block has a Gas reading, as recognized by Domoticz apparently. see: 2017-05-04 16:20:37.291 (Smart meter ...

PM is okay. Heb nog geen PM rechten. Zie ook nog geen mogelijkheid om een file mee te sturen. Hieronder een copy van één datablok. Weet niet zeker of Gas er bij zit. Lijkt veel minder vaak te worden verzonden volgens het Log. 1-3:0.2.8(50) 0-0:1.0.0(170504123914S) 0-0:96.1.1(4 ...

Can you forward me a P1 datagram so I can have a look?

Met alle plezier
Just tell me how to make a 'datagram'. Suppose this isn't the same as the log under settings.

Hello. New user here. Very impressed with Domoticz so far :D Just had my new smart meters installed yesterday, and have a Raspberry PI connected running Domoticz as slave to another RPI. Both were on stable version 3.5877. Smart meter was recognized and Energy and Gas were available as hardware ...
