This fork of esphome adds a modbus component that allows controlling devices via modbus/rs485

The modbus_controller component is now part of esphome see esphome#1779 If you are still using the modbus_controller code from the modbus_component branch please note that there are a couple of changes in the YAML definitions. See modbus documentation for more details about the required changes.

Please switch to the esphome dev branch or if you are using external components change it to

external_components:
  - source:
      type: git
      url: https://github.com/esphome/esphome
      ref: dev
    components: [ modbus, modbus_controller ]

There won't be new updates to the modbus_component branch (this branch). I will continue to use the 'testing' branch for new code but generally recommend switch over to https://github.com/esphome/esphome
