If the smart home devices are wireless, how often do the batteries need to be checked and replaced?

The smart home system is designed to monitor the life of the batteries in all the wireless devices. This can be seen on the dashboard interface.  We include a user manual with each system that will provide details of battery maintenance for each device.  Typically we would recommend changing out the batteries at least annually and can offer support with this if required.  

We also offer subscription packages, the essential-plus package provides an annual check and replacement of batteries.
