What is it?

After a software shutdown, the power on a Raspberry Pi needs to be toggled to reboot. This is usually done by toggling the power to the Raspberry Pi. This becomes an issue when a Raspberry Pi is deployed remotely e.g. for monitoring temperature in a refrigeration unit or using a Pi with solar panels or other green energy sources or using a Pi in an automobile etc.

PiZ-UpTime PLUS is an intelligent UPS in a Raspberry Pi-Zero form-factor. It is designed to be used with regular Raspberry Pi’s e.g., Pi-3 and Pi-4, Pi-Zero etc. with a 40 pin header. To use a PiZ-UpTime PLUS, connect a Li-Ion battery and start the provided Python script.

Battery not included.

Why did you make it?

I got tired of toggling the power to reboot the Pi after a soft shutdown.

What makes it special?

PiZ-UpTime PLUS allows different operating modes.

For shutdown they are:

• Initiate a soft shutdown once power fails, giving enough time to complete the shutdown properly. The duration the UPS operates is set in the Python script.
• Operate as a UPS till the battery runs low or the power returns. If the battery runs low, initiate a soft shutdown. Battery low level is configured in the Python script.

When power returns:

• Start the Raspberry Pi immediately.
• Wait for a designated period for power to stabilize or wait for other sensors / devices to come up before starting the Pi. The wait period is set in the Python script.

The operating modes can be mixed or matched as needed. LED’s provide operational information. Sample Python code provides information on operational parameters like Vin, Vout, Battery V, Input Current, Battery Current and temperature (on the board).

More details in the Description PDF. Comparison to PiZ-UpTime is also in the document. User guide explains the Python variables, I2C communication with the PSoC on board and how the operating modes can be set.
