This is my rework of the STM8 software for ESP14 Dyimore board. It delivers sensor readings in packets for parsing with ESPHOME.


  • prebuilt/ - A ready to use hex to flash STM8
  • esphome/ - Sample esphome configuration

For detailed writeup and a 3d-printed enclosure check out my blog:


Modbus slave implementation for the ESP14 BH1750 HDC1080 BMP280 sensors module. This software only for STM8 part of this module. Compiled with IAR EWSTM8 and QtCreator as an editor.
