Since this issue has been closed, does that mean this HA integration works with the water meter aswell?
Nope. It never happened. But I forked this and made https://github.com/kristianschneider/ha-multical_21
Wonderful! I will try your component then!
Nice work on your fork! Looking at the diff, it only seems that this integration is missing sensor V1Reverse (243)
@kristianschneider I have just received the USB to IR, and tried to attach it to my FlowIQ 2200.
I got two m3 reading in HA, by trial and error, but now it does not read anymore.
Do you still have yours attached and how did you do it?
Hi Jakob. It is not attached as per say, but basically just resting on the meter. I plan on creating a 3D printable bracket at some point.
It has been running for a couple of months now without any issues. On your home assistant device perhaps try and do a dmesg and see if the USB disconnects or something. If you are using a rasperry pi ensure that the powersupply is big enough.
Hi again,
I have now tried to remove and install the module again, in different orientation with the reader on the meter, and got it working again - this run lasted 3-4 readings over 3 hours.
Beside that, I have attached 2 additional magnets to the top end of the meter, and the display changes if interferred with (so I guess it puts the meter into some kind of reading mode).
But now again, the state in HA becomes 'Unknown' after a few hours. When disconnecting the USB it changes to 'Unavailable', and reloading the module in HA, the state changes back to 'Unknown'.
The reader is connected to a RPi 4 running only HA with the original power supply 5,1V = 3,0A.
So is this due to the power supply is too small or that HA disconnects the USB somehow?
with 3A you should be ok.
It sounds like a hardware issue somehow. I would check the logs on your Pi.
You could also try and enable debugging to see if something meaningful shows up in the HA log

Hi @kristianschneider Thank you the repository, it saved my day :-) Did ever create a bracket for the Multical 21?
