In a nutshell this is a pretty looking ESP32-based box with display and buttons. Do with it what you will. It needs low voltage and the basic unit comes with internal battery supply. instructions, 0.1” pin leads and a USB C lead for charging and serial connection.
I just HAD to order one and so I thought I’d put a note in here for people into the ESP32 and I’m already seeing responses including a useful note from Bob H and comments from others. All in all I’m already convinced I need this gadget on my hallway wall even though I’m not yet entirely sure what to do with it. Perhaps people who are ahead of me might write in soon to save me re-inventing the wheel.
