- # Installation guide
-
- The code must be compiled into a firmware using ESPHome 2021.8.0 or later. Therefore, a prerequisite
- is that you have ESPHome up and running in some form (command line, docker container, web dashboard,
- possibly from within Home Assistant as an add-on). For information on this, please refer to the
- documentation on the [ESPHome website](https://esphome.io).
-
- The component code is distributed directly from GitHub. You will not have to download and install
- the code manually. This leverages the [external components](https://esphome.io/components/external_components.html)
- feature.
-
- Before you can compile the firmware, you will have to create the YAML configuration file for your
- device. You can take the [`example.yaml`](../example.yaml) from this repository as a starting point, and
- modify that one to your needs. Detailed information about the YAML configuration options can be
- found in the [Configuration guide](configuration.md).
-
- After these steps you can let ESPHome compile your firmware (`firmware.bin`) file. This firmware
- can then be flashed onto the device.
-
- Like normal with ESPHome, the first time you will have to flash the device using a serial interface.
- After this initial flashing operation, you can flash new versions of the firmware using the OTA
- (Over The Air) method.
-
- See [the flashing guide](flashing.md) for hints on opening up the device and flashing its firmware
- using the serial interface.
