I have 3 leak sensors and have had them for several years. 2 are SmartThings and 1 is Aeotec. Recently, I have found that these devices have all gone offline and I have been unable to get them to stay online no matter what I try. I have replaced the batteries, re-paired the sensors, and tried simply removing the batteries and then putting them back in.

In every case, the sensors go online but only stay connected for perhaps an hour or two, then they drop out.

Anybody know what might be going on here?
