This component provides an implementation of Opentherm protocol with ESP-IDF. Tested on ESP-IDF > 5 version.
Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>.
- A development board (e.g., ESP32-S3-DevKitC, ESP32-C6-DevKitC etc.)
- A USB cable for Power supply and programming
- An opentherm adapter
See Development Boards for more information about it.
Open the project configuration menu (idf.py menuconfig).
In the OpenTherm Configuration menu:
- Select GPIO in pin
- Select GPIO out pin
Run idf.py -p PORT flash monitor to build, flash and monitor the project.
(To exit the serial monitor, type Ctrl-].)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
