You got something out of this. I am trying to do the same, but I want to know if the values will appear in m3

Probably 1 ticks = 10 l

@michal_pu Did you somehow solve the QA for converting pulses to flow? I have the same problem, but I can't find a solution and I can't write a QA.

Did you try checking the pulse meter? the flow and the reading on there should be the same

Is this topic still alive? I have been playing with water meter that has a magnetis switch and with that i can make pulse that smart implant detects. Mine water meter has 1pulse = 1liter. So i made a little QA with it because i was learning to do LUA programing. i used variables to store the pulses and calculations. I used scenes for counting the pulses and reset them and i use QA to display values

With my QA i can see the calculated asumed watter flow per hour (it counts pulses every 30sec and multiplies with 120)

it will also display max calculated average flow per day and display hour when it happened.

then qa also displays liters counted in the curent hour, day, week and month and it also stores the value of previous hour, day, week and month.

I also made it to display the calculated aused flow on the dashboard.

now i dont think u will figure out what is what in the lua cose of the QA but that just makes sence to me ._.

Hi JureZ,
your interesting solution of the QA water meter would be useful to me. It would be possible to post the scene you use to load the impulse and connect to the QA.

JureZ · June 28, 2023

Sure. Here is the lua scene that counts the values every time the sensor sends pulse. I did it so lua scenes stores values into variables. and then those variables are used in QA.
