+
+```yaml
+  id: IDENT
+```
+
 Configuration variables:
 
 - **username** (*Required*: The username of an user with access.
 - **password** (*Required*): The password for your given admin account.
 - **away_temperature** (*optional*): Heating setpoint when away mode is on. If omitted it defaults to 16.0 deg C.
+- **id** (*optional*): Thermostat identifier
+
+To find your thermostat identifier, log into your account, choose a thermostat (if applicable) and then look at the URL. It should look something like this:
+
+```
+https://mytotalconnectcomfort.com/portal/Device/Control/1234567
+```
+
+In this case, the identifier is `1234567`.
