Olga Shpigel presented on the architecture and design challenges of the CatGenie AI IoT solution. The presentation covered the live demo, architecture overview, dilemmas in device onboarding, connectivity, and hardware limitations. It also discussed how they addressed these challenges using Thing Building Blocks (TBB), a framework for building IoT solutions that includes client and device infrastructure, core libraries, and cloud services on AWS. The presentation was aimed at sharing lessons learned from developing a real-world IoT product.

7. IoT Design Dilemmas

8. Your R&D Team
Dilemmas – Device on boarding
 How the device gets its certificate
◦ Factory
◦ Using the mobile when the user setup the device
◦ JIT certificate registration
 How to prevent a user from registering the device of his
neighbor
 WIFI SSID changes

9. Dilemmas – The chosen protocol
 MQTT cons
◦ Cloud costs
 MQTT pros
◦ 2-way communication is native and scalable

10. Your R&D Team
Dilemmas – Device connectivity
 How to handle device going
offline
◦ Cloud point of view
◦ Device point of view
 Operations vs configuration
◦ Play/Pause => topic
◦ Change volume, machine mode
=> shadow

11. Your R&D Team
More Dilemmas
 Mitigating HW limitations
◦ Memory size
◦ Messages length
◦ Open connections (MQTT+HTTP?, cloud storage, etc.)
 Firmware update
◦ Automatic or approved by user?
◦ Interruption in the middle of cycle
◦ FW package validation - security
◦ FW installation failures, rollbacks
 Limitation of Remote Operation
◦ What operations to you want to allow remotely and what operations you
want to allow only locally
