Need your support to findout if there is any compatible water meter to my water installation:
As you can see in picture it doesn’t have the a red water consumption arrow for total water usage, that most water meters are tracking.
(I have red arrows for each figures and black cross that is rotating with the water flow)
Found this option but are not sure if someone have integrated with HP23.
This one might be compatible, while your meter seems to have a rotating flow indicator

To make sure, just contact these guys:

(I’m not affiliated in any possible way)
It seems it can be connected via MQTT, maybe that is an option for you?
Thank you for your proposal @Peter_Kawa. I have already checked with https://smartgateways.nl and unfortunately received this answer:
“Thanks for your mail. Unfortunately your meter doesn’t give any pulses when water is used. I don’t have a solution for you.”
Thanks @JPe4619 , this could be a solution! I was hopping for an “of the shelf solution” but this might be the backup solution.
Homewizard wont work either as it depends on same method (magnet impulse on rotating wheel).
So I have now purchased an ESP32 CAM and installed AI on the Edge to read the water meter:
I have installed MQTT Broker, Client and Hub.
I have installed MQTT explorer to read messages.
I tried to crate a virtual device by using MQTT Hub:
{
“meter_water”: {
“capability”: “meter_water”,
“stateTopic”: “watermeter/main/value”,
“setTopic”: “”,
“valueTemplate”: “”,
“outputTemplate”: “”,
“displayName”: “Water Meter”
}
}
Goal:
I want to read the water meter.
Use the values in Power By Hour summary.
Detect if any leakage in house. Should have 0 water flow for certain hours/day.
Questions:
First basic question: Why do I need to install all these apps. Why is not all functionality include all of it into one MQTT app?
Am I on right track? Is there any existing easy tutorials to explain how to achieve this? Is there a smarter way to achieve this?
How do I get the values into virtual device?
How do I get the values into Power by Hour?
I fanally solved it. I was not correct logged in at MQTT Client 
Can I calculate water flow (vattenflöde) directly in MQTT HUB virtual device??
Hello, do you think that water meter from homewizard would work with this type of analogue water meter?
Thanks for your reply in advance!
I already did, but it is not really helpful tbh. My brand should by supported, but looks different than pictured analogue. On the other hand, unsupported analogue also looks a bit different. So hard to say 
. I will probably try to contact directly homewizard.
I am not from Homewizard. I am a hobbyist that spends his free time on the Homey/Homewizard app. I really cant tell/say if it works or not so sorry for that. What I can see it is a sensus but thats it. So yes maybe? 
I checked with Homewizard about a different type of water meter, and they told me that as long as there is a metal component rotating when water is used, it should function properly. Their water usage meter operates on inductive technology, so it requires the presence of metal to detect flow.
Correct but still those frames (mount brackets) must align with the sensor on top of that induction rotation wheel. Else, there is always ducktape. 
So it seems like mine could work as I have metal arrow in there.
Nearby power as well? Else API of the watermeter womt work.
Why do I need power? Aren’t batteries enough?
For Homey integration it must be usb powered. In battery mode you only get 4 times water measure a day to Homewizard Energy cloud. If its usb powered it will be realtime and you can enable the local api interface of the device which is mandatory for Homey/Home Assistant integration.
Oh god, then it is useless for me 
Sorry, battery cant keep wifi active polling based so it must be usb powered.
