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")
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)
