Hi 
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?
Nice project, but I wonder if all this arduino ecosystem is required. Maybe the Water Flow Meter / Sensor with an ESPHome would actually be enough, but have no idea how to assemble and configure all this. Would probably require some specific / adapted firmware for ESPHome.
No its not =) ESP32 is sufficient =). Actually I follow this guide! Works pretty well! I’m just with setting up the pressure sensors…
Hi @bf8392 ,
I am following your paths and recently added energy consumption monitoring through Slimeleezer+ and now looking for a water monitoring HA integration.
Did you succeed with your project? Could you please share your experience?
Thanks!
So did you ever find a solution to this?
I’m located in ville de luxenbourg, and they don’t seem to have water sensor hooked up to smarty (yet?).
The water meter only has a 868MHz transmitter, with which I guess they periodically read the values out with from the street.
Unfortunately not. Please report here if you find any solution!
I had the same problem. I resolved the problem with an Esp32 with camera.
You can find the documentation here.
GitHub - jomjol/AI-on-the-edge-device: Easy to use device for connecting "old" measuring units (water, power, gas, ...) to the digital world.
I use slimmelezer to and I spoked with the commune to get the data from the smart water meter they installed at my home. They told me, that everything should work. It didn’t, therefore I adopted for the esp32 with camera solution.
After moving away from gas at home the configuration changed and I didn’t need the gas consumption anymore. At this time the data of the smart water meter was switch to another channel an is now the gas reading. Via template it was transformed into they right class.
Personally I think the problem is at the slimmelezer level. After the channel was switched the reading were immediately there, so the problem could be that slimmeleezer only reads one other/secondary channel.
Best regards.
Thanks, I’ll try to have another go with the ai on the edge. Already tried it, but the installed sensus water meter (transmitter) is basically blocking the view on most of the water meter numbers and dials, so I’ll try another positioning to get at least a partial reading/view.
I’ll also try to contact the commune to see what they say.
Hey sorry for the VERY late reply…yes I built it with a turbine sensor and it works pretty well! Unfortunately one of them died due to corrosion, so I had to replace…but besides from that I’m happy =)
There is an M-Bus integration of HA you can try…I never advanced with this, as you need possibly a decryption key…
