Are there plans to add read of connecter water meter

[PeterSchops]

In Belgium next to the gas meter also a water meter is connected. So it would be nice to also read out these values.

If you can dig up info about the obis codes used for water, then, no problem, I csn add water.Verstuurd vanaf mijn iPadOp 10 dec 2024 om 00:15 heeft PeterSchops ***@***.***> het volgende geschreven: In Belgium next to the gas meter also a water meter is connected.

After some searching I managed to find the information on the internet. It seems to be very similar to the gas readout, so it is probably not very hard to add it. But it needs to be added in multiple places.

ObisId 0-2:24.2.1

.7.0(002.31A)
0-0:96.3.10(1)
0-0:17.0.0(999.9kW)

I can add the water meter. That is not too hard. The trouble is that the Belgian obis codes are a bit messy and that it is tricky to detect which is gas and which water (0-2.24.2.3 and 0-2.24.2.1) For gas it was In NL the OBIS reference is: 0-1:24.2.1 In B the OBIS reference is: 0-1:24.2.3 but I have found a ciomment that BE is/has switched to the NL code. From your data, I assume 24.2.1 is water, not gas

The .1 or .3 at the end seems to refer to the measurement type (1: base value, 3: non-temperature compensated)

0-1:24.1.0(003)                            gas-meter mbus id
0-1:96.1.1(37464C4F32313232313439303732)   gas-meter id DIN43863-5 (fluvius) format
0-1:24.4.0(1)
0-1:24.2.3(221028214000S)(00032.932m3)     gas-meter reported value (.3 is non-temperature compensated value)
0-2:24.1.0(007)                            water-meter mbus id
0-2:96.1.1(3853455430303030323136343232)   water-meter id DIN43863-5 (fluvius) format
0-2:24.2.1(221028213843S)(00004.332*m3)    water-meter reported value (.1 is base value)

When I look to implementation somewhere else, I saw that for gas it was favoring the .1 measurement. But when no data is found for .1 it would take the .3 value.

Peter, In theory this version of the firmware (github/narfight’s fork of mine) now contains water and gas readings in MQTT. See https://github.com/narfight/P1-wifi-gateway for the installation guide. Connexion initiale : Le module crée un réseau Wi-Fi P1_setup_XXXX. Connectez-vous à ce réseau. Accès à l'interface : Accédez à l’interface de configuration via http://192.168.4.1 <http://192.168.4.1/>. Here is the new (untested, as I am not in Belgioum) firmware. Potentially water and gas are swapped.

Peter, contact me by email for the firmware mentioned above. [email protected]

I forked a fork of your project, and added the readout of water.

Adding the readout itself was not so hard in the end.

For the moment my hardware is working without the buffer, so I need to invert the communication. So my version will not run on your hardware. But I plan to still fix that.
