The Golioth Green Demo was just recently released on YouTube. It showcases one of the hardware demos we had at Embedded World in June of 2022. Meant to be a simulation of a greenhouse, the demo takes a reading of light intensity in the area and then uses a control algorithm to modify the light output of a lamp that has been connected to the cloud over WiFi.
The Green Demo contains an nRF52840 development board in the Aludel form factor, uses an APDS9960 light sensor, and talks to Golioth over Ethernet using the W5500 chipset on a Click header breakout.
