Brand new, apparantly one pulse/litre but no mirror
https://tweakers.net/pricewatch/428619/elster-pulssensor-falcon-pr6-voor-watermeters-elster.html
is meant for my watermeter... But 82,50, that's a lot for the bit water I use.... But perhaps in the future...
I think the optical sensor can see the difference between the white background and the red dial surface.
I've tried different placements of the youless meter but the water consumption won't leave the 0L/min. Can someone please explain the placement of the youless meter or give me some directions to fix this issue. one other thing which might be of importance could be a rather slow network performance (ethernet over powerline adapter). I've also noticed that there was a red blinking light coming from the sensor when starting the youless meter, should this red light blink more frequently to capture the rotating mirror or should it only blink once during startup. Anyway some assistance would be appreciated. Thanks in advance.
It is experimental, so the setup requires some attention. I will give a more detailed howto guide here.
Step 1:
Enable the optical sensor in the Youless by selecting "analogue" as the electricity meter type. Don't worry: your P1 meter will still work! The LED on the bottom of the youless will now continuously be turned on.
Step 2:
Placement of the youless on the rotating mirror. First cover half of the rotator with black tape like this:
Then place the youless so that the light of the bottom LED is centered in the non-covered part of the mirror.
Step 3:
Adding the water meter device in Homey
Step 4:
Checking the right placement of the youless. Switch on the "log raw optical data" in device settings.
Now open a tap in your house or flush a toilet to use water for about 1 minute. Then go to Homey insights and check the raw optical data you collected. It should look similar to this:
Optimize the placement of the youless device on the water meter to get maximum difference between the top and bottom values. For me the minimum value is around 450 and the maximum value is around 900. Try to get at least 300 difference between max and min. Check if the max and min values in the device settings match the graph in insights. If after replacement of the youless device the max/min values are incorrect you can change them manually.
After optimizing the placement of the youless, turn off the "collect raw optical data" because this mode uses a lot of Homey and network resources! You can also switch off "automatic calibration", since this should now already have filled in the max and min values.
Step 5:
In the device settings, enter the actual water meter value and check the pulses/m3 setting. The pulses per m3 are usually 1000 (meaning the mirror will rotate 1000x per m3, which is the same as one rotation per liter).
Now it works!
I rewrote the enelogic app from the ground up to make it compliant to the new Homey sdk2.
I added password support for youless devices in the process.
I also added filtering techniques to get rid of unreliable meter readings (this is actually caused by a bug in the Youless firmware, and will be solved in an upcoming 1.4.1 firmware of the LS120).
Because 2.0.0 it is such a big update I have entered it as a beta in the app store. If some beta testers could give i ta try and let me know how the migration works, I would be obliged. I added a debug log screen in the app settings tab of Homey.
Is it also possible to read Gas values with the LS110?
I don't see any difference between the LS110 and the LS120.

Great to hear you like the app, and super that you want to support in getting native youless support for the water meter.
Could you send a message to Youless about the water meter request? You can mention my name (Robin de Gruijter) so they know exactly what it is about
There is a contact form for youless available here: http://youless.net/contactformulier.html
The youless device needs external power (I use power from a free usb port on my router), and I believe a pulse meter also needs power.
After quickly checking the benext site I think that indeed certain smart meters provide power over P1, but that would depend on the type of smart meter you have.

Trouwens voor 10 euro en wat tijd kom je ook een eind met het bouwen van een P1/S0 met wifi connectie

niet dat ik hier zin(lees tijd) in heb maar misschien voor de andere onder ons. ;-)
