Node-Arduino connects after MQTT in nodes

On a Pi Zero W, I have an Arduino connected via ttyUSB0 running the StandardFirmataPlus example sketch. If it wire a MQTT In node to an Arduino Out node, the mqtt in node fires on a full deploy before the arduino out node connects. Is there a way to delay the mqtt connection only on deploy or other strategy to deal with this?

edit Only seems to be an issue on a full deploy

If your prepared to always do a full-deploy, then node-red-contrib-queue-gate could do the job for you



It will let you delay any messages at startup (assuming it activates quick enough to catch the 1st message from your MQTT node)
