Witty pi 4 power output (compatibility with pi 5 5a requirement)

There was only a software update for Witty Pi 4 to be compatible with the pi 5, which would not make Witty Pi 4 to output more current.

The pi 5 doesn't need 5A current unless you are fully loading it, usually it is not the case, and 3A current is already enough for most tasks.

Thank you for the quick response! 

According to the Rpi documentation: "For users who wish to drive high-power peripherals like hard drives and SSDs, while retaining margin for peak workloads, a USB-PD enabled power supply capable of supplying a 5A at +5V (25W) should be used."

This is my use case, hence my concern. 

It appears that powering on/off can be scheduled on the Rpi with the RTC real time clock "You can set a wake alarm which will switch the board to a very low-power state (approximately 3mA). When the alarm time is reached, the board will power back on. This can be useful for periodic jobs like time-lapse imagery."

Could you explain the benefits of the witty pi 4 for the pi 5 now that the RTC is integrated into the pi5?

Thank you. 

@physical_science As far as I know, the voltage on the +5V pin in Pi5's GPIO header will stay when Pi5 enters STANDBY state. If you have HAT connected to Pi5, it will continue being powered when Pi5 is sleeping, which may consume significant current.

Witty Pi also provide the possibility to turn on/off the defvice according to input voltage and temperature.

Witty Pi's software provides a scripting interface, which makes scheduling much simpler.

However you should try the on/off scheduling with Pi5 built-in RTC first, there is no need to add more hardware if the build-in system already meets your needs.
