It would be helpful to have a central point to check the battery status of all security devices rather than having to go to each one to make sure batteries are ok. I know that the devices will alert me when the batteries are low but I tend to err on the OCD side and like to see where they are, rather than just “exhausted”, on a regular basis. I can plan better, have replacements on hand and get a better feel for overal usage rate. One stop shopping for battery status across all devices.
