This is a great idea. Slow leaks - especially in walls - give me nightmares! Existing solutions all come with major caveats:
Water detectors need to be spread out, and are a pain to get behind walls
Manually watching the meter is a pain in the butt, and it’s unreasonable to do it often enough to reliably catch and issue before it gets expensive
Running around the house with a moisture meter is like a more involved version of the above, with more chance for user error.
Thanks. Detecting slow leaks while also conserving battery life is tricky so I opted to do it in hardware with digital logic. I keep a count of all of the low speed revolutions of the magnet inside of the brass housing. It needs more testing, but it seems to work for now.
Really excited to see the finished product!
