Little projects to play around with an ESP. In the first place all the code was implemented using the Arduino programming language and some libraries even in C++. Once I learned about the ESPHome project I migrated all my sensors to yaml files and used the ESP-flasher tool to deploy the code. In my opinion this is a very simple and fail-safe approach to easily integrate sensors into an existing home-assistant environment.
- Sources/. A few projects implemented in the Arduino programming language.
- Libraries/. Libraries to simplify usage of MQTT and HTTP requests. Probably outdated.
- Sketches/. Some pictures and sketches to show wiring diagrams for flashing.
- ESPHome/. yaml files that can be directly used to flash a firmaware on the devices using ESPHome Flasher.
ESPHome is currently my preferred way to flash firmwares on the ESP. One just needs to create virtual python environment and install some packages.
Install a new python environment with conda and activate it:
$ conda create --prefix envs/esphome-flasher python==3.8
$ conda activate envs/esphome-flasherThen install the required libraries for ESPHome
$ pip3 install esphome esphomeflasherUsually there is no configuration needed because the flasher detects a connected ESP automatically. This was at least true for a Apple M1 with the hardware directly connected via USB or via the TDI Adapter FT232RL.
A yaml file (see examples in the ESPHome/) can be easily flashed using this command (ensure to have the conda environment active):
$ esphome run my.yamlThe software will automatically detect the port where the ESP hardware is connected, compile a firmware from the given input file and write.
