I tried my hand at rigging a proximity sensor to the water meter in my house. Sadly it doesn’t have the spinning magnet for the sensor to pick up.
I looked into other options for pulling data from the meter, but for each method, my very antiquated meter had a complication that would prevent it from working.
TLDR: Any recommendations for a home water meter that’s local and integrates well with home assistant?
I’m going to check with my water company first, but likely will remove the old meter and replumb a new “smart” meter and an automated shut off valve into the water supply. I believe the current meter is leftover from before the utility added new meters further upstream, so I’d rather get rid of the rusty piece of junk anyway.
You can get used Yokogawa AXF water meters pretty cheap on eBay. They’ll put out a 4-20mA signal and as long as you get the right version for your local power you can just wire a cord to it and plug it into the wall. Only measure flow and I think temperature though.
