+# Fibaro Input Plugin
+
+The Fibaro plugin makes HTTP calls to the Fibaro controller API to gather values of hooked devices.  
+Those values could be true (1) or false (0) for switches, percentage for dimmers, temperature, etc.
+
+
+### Configuration:
+
+```toml
+# Read devices value(s) from a Fibaro controller
+[[inputs.fibaro]]
+  ## Required Fibaro controller address/hostname.
+  ## Note: at the time of writing this plugin, Fibaro only implemented http - no https available
+  url = "http://<controller>:80"
+
+  ## Required credentials to access the API (http://<controller/api/<component>)
+  username = "<username>"
+  password = "<password>"
+
+  ## Amount of time allowed to complete the HTTP request
+  # timeout = "5s"
+```
+
+
+### Tags:
