| − | '''NOTE: This interface is in alpha status and is liable to change. Once sufficient feedback has been received it will be finalized and the method names will change.''' Hubitat allows for opening and maintaining a connection to an MQTT broker from the hub. All code needs to be contained in a driver, there is no option to open an MQTT client connection from an app. Hubitat provides methods to connect and disconnect to the broker, subscribe and publish messages to topics. 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 client connection (mqttClientStatus). | |
