/**
 * This example shows how to use reports.
 * Two reports are defined:
 * * "free_heap" returns the amount of free heap space. The method is provided as lambda function.
 *   Since `interval` ist set to 0, it will not be reported via MQTT, making it accessible only
 *   via HTTP.
 * * "uptime" returns the current uptime in seconds. It will be reported via MQTT (as long as you
 *   keep MQTT enabled) every 10 seconds. Since `cache_only` is set to true, the method won't be
 *   called any more often than that.
 *
 * You can access them via HTTP GET request to `/free_heap` or `/uptime`. There's a
 * nice-ish website at `/`, listing all registered reports along with (cached) data from them.
 * If you kept the suggested hostname, this link should lead you there: http://basic-test/.
 *
 * If you enabled MQTT, "free_heap" will be published every 10 seconds. Again, if you
 * didn't change the topic below, it would be `basic-test-mqtt-topic/free_heap`.
