Adafruit IO

Adafruit IO MQTT API

MQTT broker at io.adafruit.com for publish/subscribe access to Adafruit IO feeds and groups. TLS on port 8883, plaintext on 1883, and MQTT-over-WebSocket on port 443. Authenticate with your Adafruit IO username and API key. Supports QoS 0 and QoS 1 (QoS 2 not supported); MQTT retain flag is not honored — use the /get topic modifier to fetch the last value of a feed instead. Topic structure includes feed topics ({username}/feeds/{key}), compact aliases ({username}/f/{key}), JSON/CSV suffixes, group topics ({username}/groups/{key}), throttle ({username}/throttle), and errors ({username}/errors). Wildcard subscriptions with `+` and `#` are supported for feed discovery.
