Is there a better way to do this?

Maybe "better" isn't the right word... More native to NR, maybe? I'm trying to avoid dropping to code for everything, but this works...

Basically I've got my Hubitat System Monitor and a tablet running Fully Kiosk Browser for my dashboard. When the HSM is in one of its "intrusion" modes (i.e. it was armed and a door was opened) AND the tablet senses motion, I want the tablet to capture an image using its camera and send it to me. I got the image capture and sending worked out earlier so I was working on coordinating these 2 states. There's no telling which event will come first, so I'm capturing them into context vars (global for HSM and flow for the motion activity).

So, is this a good way to accomplish this? Also, is my function to send a "ping" on startup a normal way to initialize values from devices so you don't have to wait for events from them?


From my perspective it looks like a sensible and node reddish way of doing it. I have similar flows. My only style thing (and I am no one to judge style) is to remove the logic of the internals of the intrusion string from down stream processing by adding another global (or possibly flow variable)

let value = msg.payload.value.toLowerCase();
global.set('hsm', value);

let intrusion = value.includes('intrusion')
global.set('hsmIntrusion', intrusion);
if (intrusion) return msg

Just for info
take a look here

This is a new multi system logic engine, it is very powerful and runs on any system that runs nodejs.

It is early alpha and so far systems that are integrated are
home assistant

The idea is to bring all controllers and systems under one logic engine.
more controllers and mqtt will also be integrated. It also has a built in dashboard
