Since then, I did a blog post on my setup...

https://www.lets-talk-about.tech/2023/0 ... usage.html

Thanks a lot to everyone assisting on this topic. I'm starting to have relevant figures.
I have noticed the accuracy of the usage graph is "per hour". Is there a way to have better accuracy ? like every 10 mins ?
Thanks again.
I'm preparing a blog post on that topic.

Brilliant !

Yes I initially did that, but if I'm sending the value in litre I'm getting millions of litre reported in the graph ... this is weird.
I know that 1000 liters = 1 m3 ;)

My actual value on the meter is 01617.485 (m3)
the "." which is here the decimal divider on my meter.
I have set the meter offset ...

If I'm passing the value in litre, it looks like the divider in the Domoticz setup should state 1000000 ... still playing around.

Hi There,

There are a lot of great contents here. I'm starting to go somewhere ... I'm doing further test, I will come back with my results !

Thanks everyone

I use the same "AI-on-the-edge-device" project for my Water meter.
I use NodeRed with this function to get data to Domoticz
var IDX = global.get('idxTable','memoryOnly')['Water'].idx;
var msg1 = {};
var msg2 = {};
if (msg.payload.error == 'no error') {
msg1.payload = { "command": "udevice", "idx ...

Thanks for the graph and the typo Sorted !

Thanks

I managed to create a php script that reads from the "AI-on-the-edge" and pushes to Domoticz. I have the feeling the logic is good, but I still need more hours to have complete confirmation it is working fine ...

<?php

$espIP="192.168.x.x";
$domoticzIP="192.168.x.x";

Would you mind showing me the history graph?

Hi @ flhoest,

I would recommend to use a "Counter". After you have created a "Counter" virtual device, you can edit the widget and select as "Type" water.
You send the value to the device as your Delta in liters.

Oh really ? this is awesome
I will continue testing ...

Thanks a lot for sharing your knowledge !

@waltervi,

I'm using AI on the Edge project with ESP32-CAM then I use a php script that maintain the virtual sensor.
I'm in the process of writing this script - this is why I'm asking those questions. I have a new value every 5 minutes and I'm recording current value and previous value which gives ...

have you tried the wiki?

Hi there,

Thanks for your reply, I was looking at it ... I saw this :

json.htm?type=command&param=udevice&idx=IDX&nvalue=0&svalue=COUNTER;USAGE

I have the feeling that I need to replace ...

What are you trying to measure?
A counter device can visualize the hourly, daily, monthly, yearly usage.
A waterflow device can visualize the current flow (if you send the data)

Nobody ?

Dear All,

I'm using Domoticz since 2008, but I don't know why, I only register to this forum today ... don't ask me why ;)

I'm starting to do some more advanced stuff, that's probably the reason.
I'm busy collecting the water meter data, but this is not where I need support. Part of my workflow, I ...
