Light Switch Example

Building and Flashing the Firmware

See the README.md file for more information about building and flashing the firmware.

What to expect in this example?

Supported features:

• Matter Commissioning
• Switch will connect to light when Bind command is sent
• CLIs to control remote light from switch

Bind light to switch

Update the light's acl attribute which adds entry of remote device (switch) in the access control list:

./out/debug/chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [ 112233, 12344321 ], "targets": null}]' 12344322 0

Update the switch's binding attribute which adds entry of remote device (light) in binding table:

./out/debug/chip-tool binding write binding '[{"fabricIndex": 1, "node":12344322, "endpoint":1, "cluster":6}]' 12344321 1

note:

• 12344321 : node Id of switch used during commissioning
• 12344322 : node Id of light used during commissioning
• Cluster Id for OnOff cluster is 6
• Binding cluster is currently present on endpoint 1

Useful shell commands

After the binding is successful you can send the following command to control light from switch

> matter esp bound invoke <endpoint_id> <cluster_id> <command_id>

here, endpoint_id, cluster_id, command_id of switch must be given in hex format

e.g.

• Power Off command

> matter esp bound invoke 0x0001 0x0006 0x0000

• Power On command

> matter esp bound invoke 0x0001 0x0006 0x0001

• Toggle command

>  matter esp bound invoke 0x0001 0x0006 0x0002
