A hackable & portable MQTT-powered mini dashboard and control center.
For clarity, in this specific configuration, the display above shows:
- Left panel - The states of MQTT "smart" switches. Clicking turns them ON/OFF
- Top right panel - Soil moisture status of some of the plants around the house
- Bottom right panel - Current temperature in different rooms
The main components in the photo above are:
- An ESP32 development board
- A 2.7" SHARP Memory Display by Adafruit
- A rotary encoder (similar to this one from Adafruit)
- Three mechanical switches from Pimoroni
The core software should be fairly hardware-agnostic and the concrete implementations should be relatively portable to a bunch of other boards and displays.
As an example, this repo contains a pure software implementation of the whole system. Here it is running on my macbook:
The software is organized into three directories:
code/lib/- Platform-agnostic core. Relies on abstract input/output systemscode/arduino/- Arduino instantiation of the input/output systems & MQTT clientcode/sdl2/- SDL-based software-only instantiation of the input/output systems & MQTT client
The .stl files for the 3D printed frame can be found under case/stl/.
