Errata

These are corrections of errors found in the book Getting Started with ESPHome only after its publication:

Everywhere

In ESPHome 1.19, the order of the configuration file and the command has been changed in the command-line interface. So instead of esphome config.yaml run, you now execute esphome run config.yaml. The old format is still accepted for now, but will be removed in a future release.

Chapter 2: Preparing your ESPHome environment

page 28: The --upload-port option has been renamed to --device in ESPHome 1.19.
page 36: Due to an ESPHome update, you need to add wifi and api components to the chapter2_substitutions.yaml file, otherwise the configuration doesn't compile. This is fixed in the chapter2_substitutions.yaml file in this repository.

Chapter 7: Displays

page 133, 137: For the T-Display's display platform st7789v you now need to specify the option model: TTGO TDisplay 135x240. This is fixed in the chapter7_tdisplay_mqtt.yaml file in this repository and in the chapter7_pages.yaml file in this repository.

Appendix

page 148: To compile the custom integration example with the uFire SHT20 library, you now need to add "Wire.h to the global list of libraries in your ESPHome configuration file, before "uFire SHT20". This is fixed in in the appendix_sht20.yaml file in this repository.
