Hello, Forgive me if this has already been answered and I acknowledge that the witty pi3 has been EoL for a couple years.  

I have them stacked on a pi zero w v1 and the Witty shows up sometimes but not all the time.  Power button works fine all the time.  Could they be conflicting i2c?   Do the pogo pins on the zero4u use i2c?

Thank you,

The pogo pins on Zero4U are for VCC (5V), GND, D- an D+, so they are not using I2C.

Most probably it is due to unreliable GPIO connection, specifically the SDA and SDR pins.

You may want to check the header soldered on your Pi, as well as the female header on your Witty Pi 3 Mini. All pins should be well soldered.

Cool.  It totally was a connection problem. Didn't know the pins were supposed to stick out the top.  Thank you for the quick response.
