This particular device is some version of functional, with some dim display segments and plausibly faulty touch regions. Display/buttons communicate with the main power and relay board using something like serial communications around <strike>1200bps</strike> 600/625bps. Reverse engineering the communication protocol to implement an alternative control interface. So far blinky and "singing" CW has been achieved using oscilloscope and logic analyzer dumps and then re-creating the signals using an ESP32-S3 running Micropython.

Recovered as part of unrelated e-waste pickup of Coffee Brew bits.
