Battery Status for HomeMatic is a very simple application to report the status of your battery powered HomeMatic home automation devices. Is a battery going to be empty soon? What kind of batteries does the device need? When did I last change the batteries? How long do they usually last? The app gives answers to those questions. The application requires a HomeMatic CCU base station: a CCU 2, CCU 3 or RaspberryMatic. Access to the "Remote Homematic script API" may need to be enabled in the CCU firewall settings. This application does NOT work with the "Homematic IP Access Point" (the cloud based base station).
