Insteon Thermostat with Node red

I currently use an Insteon Thermostat with home assistant, and it works well. I also use node red for a few automations. I like the visual approach to automating. I was looking to add some automations into that are integrated with my Thermostat. I am assuming I will have to use JSON to initiate any commands. Would you have any Idea what that might look like. If I had some basics, I could test it in Node Red until I get some results.
