Voltage logging for built in P1 logging script

[roblom]

Because in my region the grid voltage sometimes gets so high (around 250v) the inverter of my solar panels shuts off.
So I was wondering why this voltage isn't being logged by the built in P1 logger script in Domoticz? Hopefully someone can add this to the script.

Nobody?

Still nobody knows?

Not sure to what script you refer. The P1 readout is coded in the core domoticz program.

That's the script I meant, but in the mean time I found out that my meter is an older one which strange enough doesn't Log the voltage.

Interesting, I have only Energy, Gas, Usage L1 and deliver L1. No grid voltage.

Any idea how to show the Grid Voltage?

Doubt that grid Voltage is included in the standard P1-protocol.
At least not contained in this protocol description

If not available from the Smart Meter's P1 port, you have to find another data-source.
Often PV-inverters and PV-Loggers have this info as part of the package at their data-interface.
Also available from most kWh-meters with RS485-interface.

That's probably because that's the document for the old meters.
Here is a more recent version

The net voltage is becoming more important because a high net voltage is an indication of an overloaded network. That fact isn't new so I found it strange that they didn't thought of it before to log this.

I already use one of my UPS as data-source, but closer to the source always better.

Attached a sample of my UPS and the voltage recorded.

In the P1 source you will see that that the voltage handling is already in.
Unfortunate voltage is only included in DSMRv5 and my meter is of type DSMRv4.2.

Confirmed by reading the meter with
