<p>Domotz Public API</p>
<h3>Details</h3>
This node helps performing API calls to the Domotz Public API. API parameters can be set in the configuration section
or via node's input. The node automatically converts url and query parameters.
<h3>Inputs</h3>
An optional payload with the operation's parameters, e.g.:
<code>{"params": {"agent_id": "xyz"}}</code>
Static parameters can be alternatively defined in the
configuration of the node. Required parameters are marked with an *.
Using the "Browse" option you can select agents, devices and sensors by name (note that this feature will
use some of your API budged to retrieve the necessary resources).
