💡 Hint

Common Mistakes

Using text/plain which is plain text

Using application/xml which is XML format

Webhooks sending IoT data usually use JSON format, so the content type is application/json.

💡 Hint

Common Mistakes

Using ftp which is for file transfer

Using smtp which is for email

The HTTP protocol is used for webhooks to send data over the web.

4fill in blank

Fill both blanks to create a dictionary comprehension filtering IoT events with temperature above 25.

IOT Protocols

filtered_events = {device: data[1] for device, data in events.items() if data['temperature'] [2] 25}

Drag options to blanks, or click blank then click option'

A.copy()

B>

C<

D.items()

💡 Hint

Common Mistakes

Using < instead of >

Using .items() which returns key-value pairs

We copy the data dictionary for each device and filter where temperature is greater than 25.

5fill in blank

hard

Fill all three blanks to build a JSON payload with device ID, event type, and timestamp.

IOT Protocols

payload = {"device_id": [1], "event": [2], "timestamp": [3]

Drag options to blanks, or click blank then click option'

A"sensor_01"

B"temperature_reading"

Cint(time.time())

D"humidity_reading"

Attempts:

💡 Hint

Common Mistakes

Using humidity_reading instead of temperature_reading

Not converting time to int

The payload includes the device ID as a string, the event type as a string, and the current timestamp as an integer.
