The model item can be accessed from any context item.

The model variable also provides the function “get_space(<id>)”. This function will return the space entity associated with the given 8 character id. The space entity can then be interrogated to access the room data associated with that space in the model.
The use of this function is shown below, on line 11, the model object is used to obtain the space with id “FF000001”. On line 15 the illuminance of the space is used to defined the return value of the profile.
