My crystal ball is out of batteries. 

Had to have worked though, all the grounds are tied together in the panel anyways.Since I have you, did you do a battery bank that the generator charged when the grid went offline? 

Every once in a while we get a defective lock (batteries drain quickly), but we simply swap out for new one and problem solved. 

Tenant think we are coming to change filters and change smoke alarm batteries.   

The battery lasts about a year in each one, and the app even tells me when the batteries get low....When you deal with water damages everyday, the last thing I want to do is come home to a flooded house.Good luck, and if you would like me to go by and check it out for you, I wouldn't mind.

If they don’t need stuff, they likely won’t pull a Ross (Friends reference) and just walk off with it all, plus my lightbulbs and batteries.

Its time to replace the filter on the furnace as well as replacing the batteries in smoke detectors. 

Or batteries for the smoke detectors.One other advantage of WLB's lease is that every judge and attorney is familiar with them, most tenants have signed them before.
