An ESP-IDF component for Physical Computing<\/a><\/p>\n\n\n\n

Purpose<\/h2>\n\n\n\n

Operate a Shelly Plug from an ESP32 system.<\/p>\n\n\n\n

How it is done<\/h2>\n\n\n\n

You need to include\u00a0shelly_plug.hpp<\/code>.<\/p>\n\n\n\n

Then you define an instance of class\u00a0ShellyPlug<\/code>. In the constructor of the class you define the IP address of the shelly plug.<\/p>\n\n\n\n

Now you can use the method Switch<\/code> to switch it on or off. There is also a second version of this method with a second parameter toggleAfter<\/code>. With this parameter the shelly plug state will be toggled back after the specified number of seconds.<\/p>\n\n\n\n

With method Toggle<\/code> the state of the shelly plug is toggled.<\/p>\n\n\n\n

Where to find it<\/h2>\n\n\n\n

shelly_plug<\/code>\u00a0is published on the ESP Registry at\u00a0https:\/\/components.espressif.com\/components\/elrebo-de\/shelly_plug<\/a>.<\/p>\n\n\n\n

The source code can be found at\u00a0https:\/\/github.com\/elrebo-de\/shelly_plug<\/a>.<\/p>\n\n\n\n

How to use it<\/h2>\n\n\n\n

As an ESP-IDF component\u00a0shelly_plug<\/code>\u00a0must be included into idf_component.yml as a dependency. As usual this can be done by executing this command:<\/p>\n\n\n\n

idf.py add-dependency \"elrebo-de\/shelly_plug^1.0.4\"<\/code><\/p>\n\n\n\n

In CMakeLists.txt\u00a0\"elrebo-de__shelly_plug\"<\/code>\u00a0has to be added as a requirement.<\/p>\n\n\n\n

Now you can include\u00a0shelly_plug.hpp<\/code>\u00a0and use the ShellyPlug class in your program.<\/p>\n\n\n\n

With this code snippet the shelly plug at IP address 192.168.178.102 is switche on and off with the different methods of class ShellyPlug:<\/p>\n\n\n\n
