Abstract
Techniques for securely controlling multiple lighting devices simultaneously with a lighting control device are disclosed. Command messages may be transmitted from the lighting control device to multiple lighting devices over a computer network without routing through a remote cloud service. The messages may be encrypted and may include an incremented sequence number. Lighting devices that receive a command message may compare the incremented sequence number to a previously stored sequence number corresponding to the lighting control device. If the incremented sequence number is greater than the stored sequence number, then a lighting device may determine the message was transmitted by an authorized lighting control device and may implement any command instruction included therein. If the incremented sequence number is equal to or less than the stored sequence number, then the lighting device may determine the command message was transmitted by a malicious source and may ignore the command message.
