Wirelessly connected thermostat with flexible and scalable energy reporting

A method for collecting energy usage using an intelligent thermostat, the method comprising:

• monitoring line currents on at least one input line and load line in an electrical distribution panel using a current sensor connected to an energy meter;
• sending raw current information to the intelligent thermostat, the intelligent thermostat controlling an HVAC system for premises served by the electrical distribution panel;
• sending the raw current information from the intelligent thermostat to a remote server;
• storing the raw current information at the remote server;
• processing the raw current information using one or more existing scaling factors to determine energy usage information for the at least one load lines, the one or more existing scaling factors determined by the type of load and the type of current sensor;
• making the energy usage information available to an end user;
• receiving an input from the end user to apply a new scaling factor to the previously collected energy usage data because at least one of the one or more existing scaling factors does not match the type of load and the type of current sensor;
• and
• applying the new scaling factor to previously collected energy usage information.

A system for controlling an HVAC system and for monitoring energy usage at a premises, the system comprising:

• an energy meter at an electrical distribution panel, the energy meter connected to one or more current transformers monitoring the current in one or more input lines and load lines and collecting current information for each of the monitored lines, the energy meter further including a wireless radio to transmit the current information;
• an intelligent thermostat operable to control the HVAC system at the premises according to environmental data sensed by the intelligent thermostat, the intelligent thermostat further operable to receive the current information from the energy meter and to transmit the current information—, wherein the intelligent thermostat is networked with one or more additional intelligent thermostats, where one of the networked thermostats is designated as a master and communicates to a remote server and the remaining networked thermostats communicate with the master thermostat;
• and
• a remote server operable to process the current information from the energy meter and store previously received current information, wherein the remote server applies an existing scaling factor to the current information to determine energy usage information and groups the energy usage information according to types of loads, the remote server further operable to receive an input from a user to apply a new scaling factor to the previously received current information if the existing scaling factor does not match an instrumentation of the HVAC system and to apply the new scaling factor to the previously received current information.
