I got it. Thanks for your answers.

Thanks for your answers. Indeed,Gas can be seen. But now i'm confused: 1. If I read out the Sagemcom manually, it gives me figures about L1 and L2. 2. Above that, if I look to the graphics I can see there is a difference between 'Gebruik1' and 'Gebruik2'' My conclusion is therefor that de Sagem ...

It is a 1fase Sagemcom XS210

Being quite new to Domoticz I have the following question:

Slimme Meter P1 cable is connected to Raspberry PI 3B+.
I can "see" L1-Power, L1-Usage, L1-Voltage and L1-Delivery.
But why can'r I "see"the figures for L2?

There are only devices for the L1.
