/**
|
|
* This example shows how to use actions.
|
|
* Three actions are defined:
|
|
* * "on" and "off" set Pin 13 to HIGH or LOW, respectively. They are provided as lambda functions
|
|
* and don't care about the payload they're given.
|
|
* * "set" is defined as function reference triggering only if the payload is "ON" or "OFF".
|
|
*
|
|
* You can access them via HTTP by sending a POST request to `/on`, `/off` or `/set`. There's a
|
|
* nice-ish website at `/`, listing all registered handlers. If you kept the suggested hostname,
|
|
* this link should lead you there: http://basic-test/.
|
|
*
|
|
* If you enabled MQTT, cou can also publish data via MQTT to trigger those actions. Again, if you
|
|
* didn't change the topic below, it would be `basic-test-mqtt-topic/on`, `basic-test-mqtt-topic/off`
|
|
* and `basic-test-mqtt-topic/set`.
