Abstract
Devices of a control system may communicate with each other via a network. The control devices may be configured to form the network by joining the network and each attempt to attach to another device on the network. Attachment may be performed using one or more link quality thresholds. For example, the control device may measure background values and the link quality threshold may represent an Nth percentile value of the recorded background values measured at the control device. During a router optimization mode, the control devices may measure and store a communication quality metrics that may be used to assign the role of router devices and/or the role of leader device to control devices on the network.
Claims31
A control device for communication with one or more other devices on a network, the control device comprising:
- a wireless communication circuit configured to receive a message via radio-frequency (RF) signals;
- and
- a control circuit configured to:
- measure background RF energy via the wireless communication circuit when the wireless communication circuit is not receiving a message;
- store a plurality of measurements of the background RF energy;
- determine an Nth percentile value of the stored measurements of the background RF energy;
- set a link quality threshold equal to the Nth percentile value of the stored measurements of the background RF energy;
- and
- use the link quality threshold to determine another device to which to attach to as a parent device on the network.
A method comprising:
- measuring background RF energy via a wireless communication circuit when the wireless communication circuit is not receiving a message;
- storing a plurality of measurements of the background RF energy;
- determining an Nth percentile value of the stored measurements of the background RF energy;
- setting a link quality threshold equal to the Nth percentile value of the stored measurements of the background RF energy;
- using the link quality threshold to determine another device to which to attach to as a parent device on the network;
- and
- attaching to the parent device for performing communication on the network.
A load control system comprising:
- a first control device configured to:
- receive a message on a network link from another device on a network;
- calculate a communication quality metric that indicates a received signal strength at which the message was received;
- and
- transmit the communication quality metric;
- and
- a second control device configured to:
- receive the communication quality metric;
- determine, based on the communication quality metric, optimized network data that includes a list of control devices assigned a role of router device on the network;
- and
- transmit the optimized network data to the first control device, wherein the optimized network data is configured to cause the first control device to upgrade to a role of router device and operate as the router device on the network.
