One of my Ring steplights recently stopped working. I decided to take a peek under the hood. I was shocked at the lack of quality. There is flux residue all over and poor soldering left and right. For a mass consumer product I expected much better. They kept the SWD debug header for the Nordic nRF52 micro. I’m going to see what I can pull out of it. They left the standard Nordic UART over BLE services active too. Seems like a “don’t care if it’s ready, start selling it” scenario.
