How to trigger mqtt node using google assistant??
What do you mean by trigger an mqtt node?
Sir,actually I want to send data through mqtt node by giving command to google assistant...is there any possible way to do it??
Which part don't you know how to do, publishing data to MQTT or causing an action in node red from google assistant? Assuming that it is google assistant that is the problem then if you go to the node red flows site and search for google assistant it comes up with a number of hits, though I have not used any of them myself.
flows.nodered.org
You can use IFTTT, and a external broker, instructions here;...
However I believe Google Assistant's future on IFTTT will be no more so get a Echo instead. 
I guess node-red-contrib-nora should be helpful here.
