There are, I think, 3 ways to access data from another node:

1. The "Node-RED" way is to pass it from one to the other via a `node.send(msg)`. This is generally the best way.

2. You can access another node's .html js by calling a function in it directly

3. You can create an API function in the .js of the other node that you call from the .html of node.
