Ably Masterclass Episode 2 - Building an IoT based realtime attendance system for Slack

Ably Masterclass Episode 2 - Building an IoT based realtime attendance system for Slack

In this masterclass, Ably’s Developer Advocate, Srushtika Neelakantam, spoke about the basics of IoT and the realtime communication protocol these devices like to use i.e. MQTT.

She then demonstrated a realtime attendance system for Slack that could
• Detect the use of an entry keycard
• Publish this info in realtime to an Ably channel
• Ably, in turn, pinged Zapier
• Zapier, in turn, published this info on a Slack channel.
