Did you get anything out of that “window”?
There is apparently something actuallty spinning
The video is 2x as the normal speed.
Well look at a optical sensor that has it’s own light source to pick up the alternating clear/dark as it rotates around. Looks like two changes per rotation.
Then the math part based on the dials readings for the rotation.
Never seen something like that. I wonder if it’s supposed to be detected from side or from top…
Anyway, some analog IR tx/rx like TCRT5000 should be able to read that.
Hi,
I use the home wizard watermeter for a couple of years now. Very accurate.
I think this will work with most meters but not with mine 
Apparently i found another meter with the same mechanism. And it says it is an optical interface for a communication module.
The modules seems to not produce a pulse output as they communicate via m bus (wired or wireless) or LoRa.
The wired module is mod. RFM-MB1 datasheet
So if you get the M-Bus module you would then use the MBus Integration for Home assistant to get the readings into Home Assistant
Which is simpler than going with the LORAWAN module

i don’t think this is possible as i’m running home assistant in a container on a non-physical machine and in another network.
Even more that “accessory” seems not so easy to purchase at the moment.
I think i’m even more convinced that i need to cut off the pipes somewhere and place another water meter with a pulse output.
If you have ever used Esphome, get $1 reflective sensor and try, according to your video, it should do the job.

Does this work even of It Is all enclosed in plastic?
Likely yes. Depends on the transparency of the plastic and the distance.
Anyway, I see more questionable the dimensions. Can the sensor module be mounted a way it’s positioned within the window… Just the bare sensor is 6x10mm.
There are much smaller ones available like this, but in any case it’s not plug and play approach…

Found this one on AliExpress:

Is it a more “weatherproof” solution? Or it is a very different sensor?
It’s too big and it’s tuned for long distance.

Actually, it think the proprietary sensor is break beam one.
If you look at the video posted, looks like there are 4 sectors, two transparent and two black. So likely there’s light source on one side and phototransistor on the other. So it passes/blocks the light twice per turn.
But analog reflectance sensor should detect it as well.

So do you think something like this could work with and esp?

Should work if my interpretation of your video is correct.
Just power the receiver from 3.3V, not 5V.

why 3.3v?
i see 5v all around the product page.
If you power the receiver at 5V you need level shifting, Vout has 10k internal pullup to VCC.

So on the GPIO pin i have max 3.3v?
