Azure IoT Hub➔ Every device exists as an identity in the IoT

Hub➔ Ready to send telemetry (+ DeviceInfo)➔ Ready to listen for commands and send feedback

Change the IoT Hub tier to S1 to save money

We care about your budget. Tip of the week.

You can easily turn off these jobs, while not testing.

How can we use this

How should we position Azure IoT Suite

Good for prototyping

Ideal for quick demos

Interesting ref architecture

Not a ready to use solution

What is missing➔ Cloud 2 Cloud messaging➔ Activation / Provisioning➔ Flexibility in parameters & rules

➔ Hardcoded to Humidity, Temperature (& larger than)➔ Backend integration (Logic Apps…)
