Challenges

▪ Monitor and manage remote devices at a large scale nationally? ▪ Visualise the data captured? ▪ Manage all this data coming down?

Device shadow

What is it?

▪

A JSON document that is used to store and retrieve current state information for a device.

Message consumption

Many types of messages ▪ Alarms ▪ Inventory ▪ Leak tests ▪ Tank tests ▪ Deliveries ▪ Tank configuration ▪ Sensor configuration ▪ Pricing

Message consumption

What is the problem? ▪We need to configure a petrol station by consuming messages ensuring historical data was captured

slide-40

Tank configuration message

{ ... "LabelList": [ { "Tank": 1, "Label": "DIESEL " }, { "Tank": 2, "Label": " " } ], ... }

Tank activation message

{ ... "ConfigList": [ { "Tank": 1, "Flag": 1 }, { "Tank": 2, "Flag": 0 } ], ... }

slide-42
