3. IoT-B1. Create your FIGWAY environment
• Prerequisite
– To have a working Python2.7 environment
• Steps
– Go to: https://github.com/telefonicaid/fiware-figway
– Clone/Download at your computer.
– Go to the fiware-figway/python-IDAS4 folder.
– Check out the README.md
– Make a test running ListDevices.py in
Sensors_UL20 folder
Easy

4. IoT-B2. Create your first virtual sensor
• Prerequisite
– IoT-B1 completed.
• Steps
– Keep on at python-IDAS4/SensorsUL20 folder.
– Choose a Device ID and anm Entity ID for APP
developers usage
– We will create a SENSOR_TEMP model device.
– Execute RegisterDevice.py
• Hints
– When executed with no arguments it will
provide you with the right way to do it.
Easy

5. IoT-B3. Sending your sensor 1st observations
• Prerequisite
– IoT-B2 completed.
• Steps
– Keep on at python-IDAS4/SensorsUL20 folder.
– You will send the measurement ‘t|25’. You can
replace 25 with any number you like ;-)
– Execute SendObservation.py
• Hints
– When executed with no arguments it will
provide you with the right way to do it.
– Do not forget to use the actual Device ID you
chose before.
Easy

6. IoT-B4. Reading your sensor 1st observations
• Prerequisite
– IoT-B3 completed.
• Steps
– Get to python-IDAS4/ContextBroker folder.
– Execute GetEntity.py
• Hints
– When executed with no arguments it will
provide you with the right way to do it.
– Do not forget to use the actual Entity ID you
chose for your device.
Easy

7. IoT-B5. Create a new type of sensor
• Prerequisite
– IoT-B4 completed.
• Steps
– Get to python-IDAS4/SensorsUL20 folder.
– Check the sensor models under devices folder.
– Create a new file with a new type of sensor of
your choice Repeat B2, B3 and B4 with the
new device.
• Hints
– For learning more maybe create one device
with several kind of measurements, not just
one.
Easy

8. IoT-B6. Create your 1st Actuator
• Prerequisite
– IoT-B5 completed.
• Steps
– Get to python-IDAS4/SensorsUL20 folder.
– Repeat B3, B4 and B5 with the device
templated “SWITCH”.
• Hints
– Same as for registering/creating other devices.
Medium

9. IoT-B7. Send & Get commands to your Actuator
• Prerequisite
– IoT-B6 completed.
• Steps
– Get to python-IDAS4/SensorsUL20 folder.
– Execute SimulateCommand.py (no arguments
to get on-line help for that).
– Get the command from the actuator with
GetPoolingCommands.py
• Hints
Medium

10. IoT-B8. Connect a Physical Device to FIWARE
• Prerequisite
– IoT-B5 completed.
– You need a physical Device and a Gateway able to run
Python2.7 (it can be the same device or a RaspberryPI …)
• Steps
– Create a template if needed for your device type.
• If it is a sensor use SENSOR_TEMP as a template, if it is an
actuator use SWITCH model as template. (observations) can be
included in the same model.
– Follow B2, B3 and B4 to use your sensor manually or B6
and B7 if it is an actuator.
– Create python scripts to handle your device observations
and call SendObservation.py to send them to the platform.
• Hints
– You can improve this exercise by creating an APP ontop of
the Orion ContextBroker or a visualization portal with
CartoDB or similar (check out the ContextBroker
exercises).
