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.
For now I can learn all about it, in the Autumn when returning to the UK it could just end up as a useful central display for what will be a brand new Raspberry-Pi and ESP-Go based control system as we’ve moved from one house to another, 5 miles down the road.
The basic box with 320x240 colour display is around £27.48 sterling with free post (or not, depending where you live of course) from Banggood. Apart from Bluetooth, nothing I can't do already with an ESP8266 but then it is all in a pretty box. That has to be worth something as presentation is always an issue with home-brew IOT. I'm counting on this box being able to do heavily customised MQTT messages from those 3 buttons. I hope I'm on the right track. For now it needs a good charge.
Not sure yet what the first two errors mean but the SD error is easy enough, I’ve not inserted an SD so that’s reasonable. It clearly is picking up on my WiFi using it’s own firmware.
