NOTE: This interface is in alpha status and some users have reported issues with their hubs when using this. Use at your own risk, and please report any issues in the Community.
Hubitat allows for opening and maintaining a connection to a tcp socket endpoint from the hub. All code needs to be contained in a driver, there is no option to open a socket connection from an app. Hubitat provides methods to connect and disconnect to the endpoint, in addition it is required to create a method in the driver that accepts incoming messages (parse) and another method that will be called with any status updates for the endpoint (socketStatus).
void connect(String ip, int port)void connect(String ip, int port, [options (name/value pairs)])ip - The ip address to connect to.port - The port to connect to.options - Optional parameters to configure the web socket connection. Possible values:
eol - Optional. A character that denotes the end of a line. (Cannot be used with readDelay)// Connect with basic settings
interfaces.rawSocket.connect("192.168.1.15", 8064)
void close()
// Close connection
interfaces.rawSocket.close()
void sendMessage(String message)
message - The message to send. If this connection is a byte interface, then this must be a hex encoded String.
// Send string message
interfaces.rawSocket.sendMessage("My message")
These methods were available in earlier platform versions and may be removed in the future. New code should use the methods above.
void hubitat.helper.InterfaceUtils.webSocketConnect(DeviceWrapper device, String ip, int port)void hubitat.helper.InterfaceUtils.webSocketConnect(DeviceWrapper device, String ip, int port, [options (name/value pairs)])device - The current device that is calling the method.ip - The ip address to connect to.port - The port to connect to.options - Optional parameters to configure the web socket connection. Possible values:
byteInterface - defaults to 'false'. If set to true, messages are handled as byte arrays and will be hex string encoded.readDelay - Optional. The amount of time in milliseconds between reads from the socket, defaults to 150. (Cannot be used with eol)eol - Optional. A character that denotes the end of a line. (Cannot be used with readDelay)void webSocketClose(DeviceWrapper device)
device - The current device that is calling the method.
void sendWebSocketMessage(DeviceWrapper device, String message)
device - The current device that is calling the method.message - The message to send. If this connection is a byte interface, then this must be a hex encoded String.Methods with the following signatures must be provided in your code and will be called as described.
parse(String message) - This method is called with any incoming messages from the socket server. This is a standard method for drivers.socketStatus(String message) - This method is called with any status messages from the socket client connection (disconnections, errors during connect, etc)
