Intro

Shows power consumption (from MQTT) on a 7-segment display.

TODO:

  • put it in a case
  • mount it somewhere

Hardware

Wemos D1 mini connected to a TM1637 4x7-segment display.

Connections:

  • display VCC to Wemos 5V (3.3V also works with red LEDs)
  • display GND to Wemos GND
  • display DIO to Wemos D4
  • display CLK to Wemos D3

Software

Source code is on github.

Basically it subscribes to the MQTT stream, receives power updates and displays them on the 7-segment display.

Uses the following libraries:

  • TM1637 driver to set the digits.
  • WifiManager
  • PubSubClient
