It also let me know when workers or potential tenants came and went.The only component that needs an outlet is the base station, the rest are battery operated.

I don't know if the painters took them off or something)-replaced master shower head, toilet seats, sink, and rebuilt toilet; re-caulked shower (I used my own rainfall type shower head from day one. the other stuff I just don't know if that's my fault or not)-replaced batteries in smoke and CO alarms-replaced furnace filter-replaced back bedroom door knob ( it didn't match the others, and was like that the day I moved in)Is it not normal to give an itemized list of prices for these various charges?
