Add water meter readout to DSMR digital meters component #1873

Describe the problem you have/What new integration you would like Add water meter readout to DSMR digital meters component

Please describe your use case for this integration and alternatives you've tried: The water companies in Belgium are doing a trial with digital water meters that connect to the electricity meter to send out the messages. I assume the values can be read through the P1 port. This would be handy to follow-up water usage as well as detect any leaks due to excessive consumption.

Additional context I have no idea how to start this integration, but I'm wiling to test and provide information if needed to help developing this. I have a digital water meter installed since Monday.

Hello,

I captured a telegram via the debug option

Following lines seems to describe the watermeter : " 0-2:96.1.1() 0-2:24.2.1(230224135019W)(00045.409*m3) "

Yes, correct. This is what's mentioned from following document: https://maakjemeterslim.be/rails/active_storage/blobs/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBBZ0lEIiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--cdd9b48fd0838e89b177f03b745b23450fd8f53e/e-MUCS_P1_Ed_1_7_1.pdf?disposition=attachment

Would love to see the integration of the sensor.

A workaround I implemented today, basically with some equipment I will need for the installation of an EV and a slimmelezer I had still collecting dust

I noticed that the watermeter installed in my house is sending the measurement in the same register as used in the Netherlands for the gas measurement, so -->

1) connect P1 port of the power meter to a P1 splitter ( used : active P1 splitter from HomeWizard) 2) connect slimmelezer 1 with Esphome --> use this for electricity & gas in the energy dashboard 3) flash slimmelezer 2 with Esp-link 4) connect slimmelezer 2 in Home Assistant with DSMR Slimmelezer, use DSMR 5 (not 5B) 5) create a new variable renaming the gas output from slimmelezer 2 to device class water (if you would like to use this in the energy dashboard)

Not elegant but functioning

Here is someone that worked on it: https://github.com/peno64/slimmemeter/wiki

Can we create an official implementation? It's the one thing missing!
