Hermetry Twin

Hermetry Twin is a digital model of your sites, alive with data. It answers three questions:

• Where is each device? Every device has a place in a tree of sites, buildings, floors, rooms, lines and machines.
• How is each place doing? Each place shows the worst status and the open alarms of the devices under it.
• What does it look like? Each place can have a 2D drawing and a 3D view that move with live data.

You build the tree on Sites & Assets, place devices on it, and then use it everywhere: Sites boards, process drawings and 3D scenes, Rules cards that act on a place, and flows that look up a device’s site.

Relations	Contains, Manages, Feeds, Monitors and your own relation types, and where they are used
Site status and the status key	How a device’s status value becomes a colour, how it rolls up, and how to derive it with a flow
Locations and time zones	Latitude, longitude and time zone of an asset, and what uses them
Site views	The Sites board templates: the site table, the map and a page per site, and drill-down boards

From code: Sites and assets API.

Getting started

1. Open Sites & Assets and select New site. Give it a name and a location.
2. Select the site and Add child for its buildings, floors, rooms, lines or machines.
3. Place your devices: on the site’s drawer, Place devices, or on each device’s Placement tab.
4. Let your devices send a status key, or derive one in a flow, so places are coloured by more than alarms and connection. See Site status and the status key.
5. Create a board from the Sites template. See Site views.
