A communication rate between a cloud-based server and an HVAC controller located within a building may be controlled based on the amount of power available at the HVAC controller. The cloud-based server may notify a user if the amount of power available at the HVAC controller is determined to be low.

Systems and methods to control a communication rate between a thermostat and a cloud based server

Method to control a communication rate between a thermostat and a cloud based server

An operation alteration of a network attached thermostat to control power usage. Control wires for a heating and air conditioning system may be connected to a thermostat control circuit configured to control the system. A power extraction circuit may be coupled to the control wires configured to extract power from the control wires. The power may be put into a storage device. The power may be provided to the thermostat control circuit and a WiFi radio module. The radio module may provide a network connection for the thermostat. Circuitry and techniques may be provided to reduce power usage by the thermostat components.

Thermostat circuitry to control power usage

A low latency peripheral device sharing system has a host computer with an operating system, a kernel memory buffer, applications, device specific drivers, and a peripheral server driver. The server driver intercepts function calls invoking the local serial ports, and passes standard serial data from the application to a local area network. A device server on the local area network reads the data using a hybrid read block (semi-blocking read), and writes the data to the FIFO registers of the serial device and the remaining data to a queue for the serial device. Finally, the device server times the serial data and returns an intercharacter interval timer flag to the host computer to terminate a read operation.
