Luxembourg Water Meter/ general Water Meter

Hi :slight_smile: I have a question: I’ve successfully integrated the Current and Gas usage, using Slimeleezer + in Luxembourg. Now I want to track water usage, to complete the dashboard. I’ve a device installed here from a Luxembourg community, which is already a smart meter, and is used to read out the water usage by them:

Is there a chance I can read this thing out with HA? Or does someone know a Device I need to install to read out water consumption.

Good luck with that. In my commune they are using Home automation - sontex.ch which is using a full closed ecosystem by Sontex. Since everything is encrypted and the meter belongs to the commune, not sure we can do much about it.
However, there was a guy designing a DIY solution which looks promising Build a cheap water usage sensor using ESPhome and a proximity sensor - PieterBrinkman.com but the question: is it possible to put this over the water meter since there’s already a device over it also capturing the magnetic pulses.

@alexboss For me it would not be possible…device from the commune is blocking here…but I’ve seen another Idea which is very interesting! Someone build it with an arduino and a fow meter: Water flow rate and volume measurement using Arduino in 2020 - Arduino Project Hub

with the mysensors integration, it should work also for home assistant…

Currently I have the folloeing project:

I want to use this: Get Started with Wio Terminal - Seeed Wiki → An arduino based device togehter with a flow meter sensor ike this: Amazon.de

The problem is, that I’ve never worked with arduino, so its gonna be an adventure…

I want to achieve the following:

The WIO Terminal should also get a Gas-Sensor for the Celar, to detect CO-Leckage. Together with that, I want to wire the flow sensor, and pass both data to HA. When certain PPM for the gas sensor are reached, it should beep. All values should be shown in the display. Has anyone worked with Arduino/WIO Terminal? Will my solution be possible?
