Places are an area (amount of space) derived from an physical location. A Place is described by its map/schema and coordinates to determine its current location, where you can assign Receivers. A Place is strictly used in the context of Gateway and Location Engine terms.
Adding Gateway to a venue
To add Gateway to a venue, go to infrastructure -> Venues, select your venue. If you don't have a venue, create one by clicking 'Add Venue', then give it a name and description (optional). Then click on 'Assign devices'. Select the Gateway from the list located under the 'Cloud devices' section and click the Assign button to get the full list of actions. There click 'Assign to Venue'.
Once this is done, you will need to place your Gateway on your floor plan in Location(beta) menu.
Place creation and placing Gateway(s)
Go to Location Engine > Place, there you will see a list with all your venues.
Select the one you would like to work with and click on its name. This will take you to the Setup receivers view.
The first step is to upload the blueprints of the space where you will be using your Gateway. You can either use the default map or click on 'Edit Place' to upload your own. In this example, the layout of the first floor of a house was used. Click 'Browse files', select your blueprint or layout file (in jpg, png or gif). Then turn on the Measuring Tool, and select an area in which you know the distances involved. In the example, we know that the Garage is 19' or 580cm, so we will place the line between the two walls of the Garage and add '580' in the input field where it says 'distance in cm'.
Then click on 'Save Place'. After saving, all that is left for you to do is locate the Gateway on the map, by dragging its name from the right hand side and placing it on the map. It will be shown as a purple dot. For this example, we will place the Gateway on the garage, so we will drop it there.
If your Gateway has been configured correctly and it has power, you can go to Presence -> Live, then click on the play button and all the beacons that are in range of the Gateway will be shown there.
