1. A method of operating a computing device of an environmental monitoring system, the computing device processing at least one report from at least one environmental sensor in the environment, the method comprising: computing, based on values of physical properties of a simulated object and the at least one report, a simulated condition of the simulated object within the environment; comparing the simulated condition to a criterion, wherein the criterion comprises a parameter of the simulated object; selectively outputting an indication of an alarm condition based on the comparing; and receiving through a user interface an input of the values of the physical properties of the simulated object, wherein: the environment is managed by a user; and receiving through the user interface the input of the values of the physical properties of the simulated object comprises: associating input with an account based on credentials issued to a user for the account; and receiving the input of the values of the physical properties of the simulated object from the user.
