MQTT, or message queue telemetry transport, is a protocol for device communication that Adafruit IO supports. Using a MQTT library or client you can publish and subscribe to a feed to send and receive feed data. If you aren't familiar with MQTT check out this introduction from the HiveMQ blog.All of the subsequent posts in the MQTT essentials serie...
One feature of MQTT is the ability to specify a QoS, or quality of service, level when publishing feed data. This allows an application to confirm that its data has been sucessfully published. If you aren't familiar with MQTT QoS levels be sure to read this great blog postexplaining their meaning. For publishing feed values the Adafruit IO MQTT API...
Adafruit IO's MQTT server imposes a rate limit to prevent excessive load on the service. If a user performs too many publish actions in a short period of time then some of the requests will be rejected and an error message will be published on your /throttle topic. The current rate limit is at most 30 requests per minute for free accounts, 60 per m...
There are a few ways to send data to our MQTT API if you're writing your own client library. The simplest way to send values to an IO Feed topic is to just send the value. For example, a temperature sensor is going to produce numeric values like 22.587. If you're sending to mosfet/feeds/photocell-one you can use the raw number or a string. That mea...
MQTT is a tremendously useful protocol for building small connected devices and is relatively simple to understand and implement (if implementing networking protocols is your thing). Unfortunately, a few features of the Adafruit IO platform make it difficult for us to support the entire MQTT 3.1+ protocol specification in our broker. Specifically, ...
Feed Topic Format
Adafruit IO's MQTT API exposes feed data using special topics. You can publish a new value for a feed to its topic, or youcan subscribe to a feed's topic to be notified when the feed has a new value. 1. {your Adafruit IO username}/feeds/{feed key} 2. {your Adafruit IO username}/feeds/{feed key}/csv 3. {your Adafruit IO username}/feeds/{feed key}/json
Group Topic Format
1. {your Adafruit IO username}/groups/{group key} 2. {your Adafruit IO username}/groups/{group key}/csv 3. {your Adafruit IO username}/groups/{group key}/json
Small Topic Format
If you're using an embedded system and need to conserve space, use the /f/ or /g/topic formats: 1. {your Adafruit IO username}/g/{group key} 2. {your Adafruit IO username}/g/{group key}/csv 3. {your Adafruit IO username}/g/{group key}/json 4. {your Adafruit IO username}/f/{feed key} 5. {your Adafruit IO username}/f/{feed key}/csv 6. {your Adafruit IO username}/f/{feed key}/json
You aren't limited to just Feed based MQTT topics, Adafruit IO supports grouped feeds as well. Similar to our HTTP group data creation API, you can publish to multiple feeds or subscribe to multiple feeds through a single MQTT topic. The topics formats for publishing or subscribing are: 1. (username)/groups/(group name or key) 2. (username)/groups/...
Adafruit IO provides some built-in MQTT topics for getting the current server time. The current available topics are: 1. time/seconds 2. time/millis 3. time/ISO-8601 4. time/hours Most of the Adafruit IO client libraries provide helper functions for easy use of these topics: 1. Arduino 2. Python 3. CircuitPython
Create random data streams that can generate colors, words, numbers, or pick a value from a custom data set and send it directly to your devices. Prior to subcribing to the randomizer topic, you need to generate the topicsto get the id.
With access to weather data powered by Dark Sky, you can get hyper-local forecasts sent directly to your devices. Weather data is updated at most once every 20 minutes. When you have an IO Plus account, you can track the weather through our HTTP or MQTT APIs for up to 5 locations at a time. Prior to subscribing to the weather topic, you'll need to ...
