1. You have short power cuts from time to time 2. Your main concern is a soft shutdown of the OS to avoid SD card corruption and data loss 3. You would like to have a button to conveniently shut down and restart the OS
Safe Power monitors power input from your USB power supply and blinks green every 2 seconds.
There is no delay in supplying power in case of a power failure. The main processor and operating system will continue to run. USB and network will immediately cease operation on Raspberry Version 1. On Raspberry 2 network and most USB devices are still operational.
If power is not restored after 10 seconds, Safe Power will initiate a shutdown of the OS. Commands can be run in the OS before shutdown by modifying the script.. After shutdown of the OS a red LED blinks every 2 seconds.
When mains power is restored and stays on, Safe Power will reboot the OS and normal operation restarts. Safe power will monitor until the next power cut.
A button is provided for manual shutdown. Press the button once, the red LED will light, the OS will shut down and power to the Raspberry will be cut. Green and red LEDs will blink in manual shutdown mode. Press the button again for restart. The green LED will start to flash every 2 seconds.
