Was hoping someone in the community might have some suggestions on this...
I have about 15 Insteon leak sensors scattered about my house. They are monitored both individually by Indigo, as well as by Perry's Leak Monitor plugin. They have worked well for a few years, and have saved us from at least 2 messes.
But 2 of them have recently begun misbehaving in a strange way. They both started this on the exact same day about 3 months ago, and it was the same day contractors were working in my house, turning power off and on, etc. The Indigo Mac Mini never lost power, as it's on a UPS, but many circuits in my house were disrupted for several days during a kitchen demo, and I know that the overall Insteon network was compromised until all the circuits were brought back online because I had a much higher signal miss rate on lights/etc. for a few days.
For some reason, at this time, 2 of my leak sensors stopped sending a heartbeat. They both will still send a signal if I push the button on top, and they both will still signal a leak if tested in water. I changed the battery in both, and the behavior continues. Neither was in the kitchen when the demo was occurring-- one was on the other side of the house, and the other on my dresser (moved out of the kitchen while they were working) literally sitting right next to another sensor that is still working fine. Right now I have one sitting very close to a powerlink modem and still getting the same result. So I don't think they are in an RF dead zone or anything.
I mention the concurrent kitchen demo/power disruptions for diagnostic purposes, because I find it highly unlikely that two sensors just broke on the exact same day while the power also happened to be partially out.
Any suggestions? I hate to replace two sensors that otherwise seem to be fine, but I feel like I should be wary of ones that no longer send a heartbeat, even after a battery change.
