Redundant and selectable gateway and control elements for remote connected thermostats
A networking thermostat is described that includes a main processor and a communications processor. The main processor includes a network manager function, a master messaging function and a slave messaging function while the communications processor includes a wireless radio enabling the thermostat to communicate with other networking thermostats. The networking thermostat is able to operate in a master mode or a slave mode, where the master mode allows the networking thermostat to act as a main gateway between other networking thermostats and a remote server. When in the master mode the networking thermostat can default to a slave if communication with the remote server is lost, thereby allowing one of the other networking thermostats to become a master.
1. A networking thermostat comprising:
a main processor, the main processor including a network manager function, a master messaging function and a slave messaging function; and
a communications processor operable to communicate with the main processor, the communications process including a wireless radio enabling the thermostat to communicate with other networking thermostats;
wherein the networking thermostat can operate in a master mode or a slave mode, the master mode allowing the networking thermostat to act as a main gateway between other networking thermostats and a remote server, and wherein when in the master mode the networking thermostat can default to a slave if communication with the remote server is lost, thereby allowing one of the other networking thermostats to become a master;
and further wherein the networking thermostat can also operate in a standby master mode, the standby master mode requiring the networking thermostat to maintain a connection to the remote server such that the networking thermostat confirms its availability to the remote server and receives commands from the remote server.
2. The networking thermostat of claim 1 wherein the standby master mode can be a primary or secondary standby master mode.
3. The networking thermostat of claim 1 further comprising a network management function storing the addresses of all slaves when the networking thermostat is in master mode.
4. The networking thermostat of claim 1 wherein the networking thermostat reverts to master mode when communication with the remote server is reestablished.
5. The networking thermostat of claim 1 wherein the communications processor includes a slave message data storage to store messages to allow a quick response time in response to incoming communications from the master.
6. A system of networking thermostats comprising:
a plurality of networking thermostats each comprising: a main processor, and a communications processor, the main processor including a network manager function, a master messaging function and a slave messaging function, and the communications processor operable to communicate with the main processor, the communications process including a wireless radio enabling each of the plurality of networking thermostats to communicate with other networking thermostats;
wherein the plurality of networking thermostats form a network and each of the plurality of networking thermostat can operate in a master mode or a slave mode, the master mode allowing the networking thermostat to act as a main gateway between other networking thermostats and a remote server, and wherein when in the master mode the networking thermostat can default to a slave if communication with the remote server is lost, thereby allowing one of the other networking thermostats to become a master;
and further wherein each of the plurality of networking thermostats can also operate in a standby master mode, the standby master mode requiring the networking thermostat to maintain a connection to the remote server such that each of the plurality of networking thermostats acting as a standby master confirms its availability to the remote server and receives commands from the remote server.
7. The system of claim 6 wherein the standby master mode can be a primary or secondary standby master mode.
8. The system of claim 6 further comprising a network management function storing the addresses of all slaves when the networking thermostat is in master mode.
9. The system of claim 6 wherein the networking thermostat reverts to master mode when communication with the remote server is reestablished.
10. The system of claim 6 wherein the communications processor includes a slave message data storage to store messages to allow a quick response time in response to incoming communications from the master.
