Access from your phone or computer
There are three ways to use the system besides the panel's own touchscreen.
The web app on your own network
The panel serves the full web app itself. On a phone or computer connected to the same network as the panel, open the panel's IP address in a browser. You can read the IP off the panel under Settings → Network (the status column on the right).
The web app has everything the panel has, plus the pages that only exist there: Alerts editing, the Location map, and firmware upload from a file.
The Remote Dashboard (away from the van)
Linking the van under Settings → Remote Dashboard connects it to the hosted platform, giving you the same dashboard from anywhere with internet, plus push notifications on your phone when an alert fires.
Home Assistant
If you run your own smart home, point the panel at your MQTT broker under Settings → Home Assistant and every reading and control appears in Home Assistant automatically. The panel keeps a separate connection for each, so Home Assistant and the Remote Dashboard can both be connected at the same time — each has its own switch on its own settings tab: Activate MQTT for your own broker, Activate remote dashboard for the hosted one.
