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.

Really excited to see the finished product!
