I'm trying to set up a websocket connection to the Sense energy monitor API. The URL takes the form `wss://clientrt.sense.com/monitors/%s/realtimefeed?access_token=%s`, and thus is somewhat dynamic. I have a login flow that sets the monitor ID and access token in the flow's context, but I don't see a way to get at those values to create the URL for the websocket client config.

Is there any way to do this?

**UPDATE:** Can I use `{{ }}` in any node property field? Maybe something like `wss://clientrt.sense.com/monitors/{{ global.get("monitorID") }}/realtimefeed`?

**UPDATE 2:**

After some experimentation, I found I can put `{{ msg.payload }}` in a Dashboard Text node value, but not `{{ global.senseRealtime.payload.w }}`. But I _can_ use `senseRealtime.payload.w` as part of a `global.` inject node assignment.
