IOT ESP32 Weather Station for Home Assistant or ESPHome

I designed this setup for adding outside temperature information to my home assistant setup with ESPHome integration. Desinged to be mounted on a wooden surface.

Schematic and ESP Home config will be added soon ….

Required Hardware:

• Sensor housing:
  • DFRobot Solar LiPo Charger 
  • DFRobot FireBeetle ESP32 IoT 
  • Sensors: BMP388/BME680, ….
  • 4x 5x5x5 cube magnet
  • 6x threaded inerts M2
  • 6x countersunk screw M2
  • 4x self tapping, countersunk screw 1.7x6
  • 2x pogo pin 2x4.5mm 
• Solar panel holder:
  • 6x 1.7x6 self tapping, countersunk screw
  • 2x 1.7x10 self tapping, countersunk screw
  • 2x M3 Nut
  • 2x M3x12 screw
  • XT30 female
  • 2.5W 5-6V Solar Panel
• Sensor housing dock:
  • XT30 male
  • 4x 5x5x5 cube magnet
• Mounting material:
  • some 2.0x10 woodscrews to mount the dock and the solar panel

Why these components?

In contrast to other ESP32 Dev Boards the FireBeetle is optimized for minimal current consumption, when in sleep. Pleas also check this great comparision of different ESP32 modules by Christopher David.

The chip used on the DFRobot solar lipo charger can handle low input voltage/current quite well and still manages to charge the batter under low light conditions. Other charger chips did not deliver satisfying results.
