Hi, I'm new to Node-Red, programming and scripting but giving it a go. I'm creating a dashboard using serial data published by an Autonomous Underwater Vehicle operator station. I have all the data coming into Node-Red via MQTT and the dashboard works fine.
I have the position of the AUV plotting on Worldmap, but I would like a button to centre worldmap to the AUV position. I have a button and a function to send the msg.payload.command to worldmap but it recentres every time a position is received from the AUV not just once on the button push.
New to all this so...
