Using node.status() with a config node

General
1

I would like to use the node.status() method to update the status of a config node for the user. How can I display the node's status in the config panel?

Is there an event that is emitted when the status changes?

Got it.

RED.comms.subscribe(`status/${node.id}`,function(topic,msg){
    console.log(topic,msg);
});

There is an unsubscribe also.

Where do you show the status?

I'm showing it in the config node panel.

		/* Subscribe / unsubscribe from the NR websocket status updates for a node */
		subscribeConfigStatus: function(nodeId,handler){
			RED.comms.subscribe(`status/${nodeId}`,handler);
		},
		
		unsubscribeConfigStatus: function(nodeId,handler){
			RED.comms.unsubscribe(`status/${nodeId}`,handler);
		},

		configStatusHandler: function(topic,msg){
			switch(msg.fill){
				case 'red':    msg.fill = '#cc0000'; break;
				case 'green':  msg.fill = '#55aa88'; break;
				case 'yellow': msg.fill = '#F9DF31'; break;
				case 'blue':   msg.fill = '#53A3F3'; break;
				case 'grey':   msg.fill = '#d3d3d3'; break;
			}
			
			let shape = `background-color: ${msg.fill};`;
			if(msg.shape === 'ring'){
				shape = `border-color: ${msg.fill}; border-width: 2px;`
			}

			let container = $(".insteon-status");
			container.css('margin-top','5px');
			container.empty();

			let rect = $("<div/>",{style: `margin-right: 4px; height: 14px; width: 14px; float: left; border-radius: 3px; ${shape}`});
			let text = $("<span/>",{text: msg.text, style: "position: relative; top: -2px"});

			rect.appendTo(container);
			text.appendTo(container);
		},

Does this API still exist in v1.2.x? I am getting "RED.comms.subscribe is not a function".

I decided to override the status() method of the config node to capture the status() calls.

this.status = function (status) {
    if (status.text === 'node-red:common.status.disconnected') {
        // Handle disconnection
    }
}
