On Off shim

Hello, is it possible to use the Pimoroni on off shim on a RaspberryPi running Cayenne? It uses BCM 17 for status and pulls BCM 4 LO to power off the Pi.

You can use the Pimoroni on off shim on a RaspberryPi running Cayenne. Just may sure you dont add an actuator to pin 4 using cayenne.

Ok great, is the DS18B20 out of the question on a RaspberryPi running Cayenne with the on/off shim?

yes kind of, you adding the Pimoroni on pi makes the GPIO 4 non usable.
