guide · aiot
From Device Events to a Closed Operations Loop
Connect detection, ownership, diagnosis, action, verification, and learning.
guide · mqtt
How to Choose MQTT QoS
Choose QoS from failure cost, bandwidth, session behavior, and application idempotency.
guide · platform
How to Design a Device Shadow
Use desired and reported state without hiding uncertainty or creating unsafe retries.
guide · aiot

How to Handle Offline Devices
Design detection, queues, operator expectations, and recovery for intermittent fleets.
guide · mqtt
How to Select an MQTT Broker
Compare brokers with a workload, failure, operations, and ownership model—not a feature checklist.
guide · data
How to Select IoT Time-Series Storage
Choose a data architecture from ingest, queries, retention, corrections, and cost.
guide · ota
