The request
“Create an IoT smart home system with temperature, humidity and PIR sensors; lights, HVAC and locks; a Raspberry Pi or hub edge gateway; an AWS IoT or Azure cloud platform; automation rules; a time-series database; a mobile app; and a voice assistant.”
Then tryAdd a water-leak sensor connected to the edge gateway.Add a security camera that sends events to the cloud platform.
What is in this drawing
Read the decisions behind it.
01Edge gateway pre-processes sensor data locally
reduces cloud bandwidth and adds offline resilience.
02
Rules engine in the cloud so rules can be updated centrally; local fallback rules on edge for connectivity loss.
03DB bidirectional arrow
historical data feeds rules engine for time-based triggers.
Add a local MQTT broker on the edge for faster device-to-device messaging; add a digital twin block in the cloud for simulation-based rule testing.
