Well, in my case the phantom meter output has always been there. since the initial smart meter installation. As gordonb3 explained, before version 3.8153, domoticz would just accept any value from an external meter, so I had no problems reading the gas values: Yes. That would be me. As it stands ...

So you listed al the conditions that must be met to switch on the socket: manual switch ON, time after Sunset, or before sunrise and motion detected. Did you try putting that in blockly for a start? NB. Times in domoticz are 'reset' at midnight, so it can never be after sunset and before sunrise at ...

Good to see it working again Edgar. The funny thing is that the grid operator seems to think that the gas meter not being at ch. 1 is the problem, while the specification (and Domoticz) is perfectly fine with another channel, as long as there is just 1 gas meter. We (or better: I) simply did not ...

Hmm, I looked over that one. Is your script a 'device' script? You should see it in the filename of the script.

It seems to complain about all device-related stuff, which not allowed of the script of the wrong type.

Try to declare setpoint before your if/else statement, so right after you declared hysteresis. Then give it its value within the if/else

I'm not a lua expert, but I believe the scope of the setpoint value is now only the within the if block, and another one within the else block.

Hmm, with only one gas meter at the same time, there is no real need for channel selection.. It might be easier to just check whether the gas serial > 0 or > "" and otherwise skip it nontheless. I don't know if that is sufficient though. My meter and Edgar's seem to handle the ghost meter ...

Ah, that is very useful information. Good to see some proper data checking added to the code. Compiling my own Domoticz version is indeed perfectly doable, but it is better to tackle the real problem. When the meter was installed, the fist gas meter appeared to be faulty, so the they took a new one ...

I know, but as far as I know it always has. In a telegram I capturered last year i found the same ghost (and the actual meter on ch. 2) and Domoticz never complained and showed me the values.

Is there a way to force Domoticz to use ch.2, or to force the meter to use ch. 1?

Since I upgraded my Domoticz installation to 3.8153 I have no more gas reading from my P1 Smart meter. My current situation: Rpi 2 running Raspbian Jessie Domoticz 3.8452(beta) P1 smart meter Electricity + Gas (KAIFA) connected via GPIO serial pins The Electricity part is still working like a charm ...
