Install Jentic One Beta

Connect the Adafruit IO API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Adafruit IO API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Adafruit IO API.

Create and list feeds for sensor telemetry via /{username}/feeds

Read the latest data point from a feed at /{username}/feeds/{feed_key}/data/last

Submit batch sensor readings to a feed via /{username}/feeds/{feed_key}/data/batch

For Agents

Read and write sensor telemetry, manage feeds and groups, and look up account data on Adafruit IO.

Use for: I need to create a new feed for a temperature sensor, Read the latest reading from a humidity feed, Push a batch of sensor readings to Adafruit IO, List all feeds in my Adafruit IO account

Not supported: Does not handle device firmware updates, OTA management, or dashboard layout - use for Adafruit IO feeds, groups, and feed data only.

Use Cases

Patterns agents use Adafruit IO API for, with concrete tasks.

★ Microcontroller telemetry ingest

Hobbyist and educational IoT projects use Adafruit IO to log sensor data from a Feather, ESP32, or Raspberry Pi. The microcontroller (or an agent on its behalf) creates feeds via /{username}/feeds and posts readings in batches to /{username}/feeds/{feed_key}/data/batch. Batch ingest reduces the number of TLS handshakes a memory-constrained device has to perform.

POST a batch of 30 temperature readings to /{username}/feeds/temp/data/batch and confirm the count in the response

Live dashboard polling

Smart-home and weather-station dashboards poll Adafruit IO for the latest values. An agent or front-end calls /{username}/feeds/{feed_key}/data/last for each feed in the dashboard and renders the result. Grouping related feeds via /{username}/groups simplifies the read pattern to a single group key per panel.

Fetch the last value of each feed in group 'weather-station' and render a dashboard summary

Historical analysis

Researchers and tinkerers analyse historical sensor data - for example averaging temperature over a week or charting humidity trends. An agent can pull /{username}/feeds/{feed_key}/data with a date range, aggregate the values, and feed them into a notebook or analytics tool. This avoids exporting CSVs by hand from the Adafruit IO UI.

GET /{username}/feeds/temp/data with start_time and end_time and compute the daily average

AI agent integration

Makers building agent assistants for their lab or smart home wire Adafruit IO into Jentic alongside notification APIs. The X-AIO-Key lives in your Jentic One instance and the agent searches by intent - e.g. 'read the latest soil moisture' - without juggling raw keys in the conversation context.

Search Jentic for 'read latest Adafruit IO feed value', load the schema, and execute it for feed_key 'soil-moisture'

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Adafruit IO X-AIO-Key is stored once, encrypted, by your own Jentic One instance and injected as a header at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'read latest Adafruit IO feed' or 'send a batch of sensor readings', and Jentic returns the matching operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Adafruit IO API through Jentic.

Why is there no official OpenAPI spec for Adafruit IO API?

Adafruit IO does not publish an OpenAPI specification in this trimmed shape. Jentic generates and maintains this spec so that AI agents and developers can call Adafruit IO API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Adafruit IO API use?

Adafruit IO uses an API key in the X-AIO-Key header, generated from the user's Adafruit IO profile page. Through Jentic, the X-AIO-Key value is stored encrypted in your Jentic One instance and the agent receives a scoped execution handle, so raw keys never appear in prompts.

Can I send batch sensor readings with the Adafruit IO API?

Yes. POST to /{username}/feeds/{feed_key}/data/batch with an array of data points to ingest several readings in a single request. This reduces the number of TLS handshakes a memory-constrained microcontroller has to perform compared with single-point POSTs.

What are the rate limits for the Adafruit IO API?

Adafruit IO enforces a per-minute data throughput limit that depends on the account tier (free vs IO Plus). The OpenAPI spec does not declare exact numbers - see Adafruit's IO docs for the current ceiling, and use batch ingest to stay within budget.

How do I read the latest sensor value through Jentic?

Run pip install jentic, search Jentic for 'read latest Adafruit IO feed', load the schema for GET /{username}/feeds/{feed_key}/data/last, and execute it with the username and feed_key. Jentic injects the X-AIO-Key from the vault.

Does the Adafruit IO API support grouping multiple feeds?

Yes. /{username}/groups lets you create and list groups, and a feed can be associated with a group so that related feeds (e.g. all sensors on a weather station) can be queried as a single unit.

Can I limit what my agent is allowed to do with the Adafruit IO API?

Yes. Because Jentic One is self-hosted, you write the rules that decide which Adafruit IO operations and credentials your agent may use. Since the feed key sits in the URL path (/{username}/feeds/{feed_key}/...), you can pin the agent to a single feed so it only pushes and reads that feed's data and nothing else. You also choose which operations are exposed, so creating feeds or reading groups stays off unless you add it.
