ioBroker adapter for monitoring and controlling AC Infinity UIS WiFi controllers.
AC Infinity manufactures smart climate control devices for grow tents and greenhouses — fans, temperature/humidity sensors, smart outlets and more. For device information see the AC Infinity website and the Controller 69 Pro product page.
Deutsche Dokumentation: docs/de/README.md
Only tested with: Controller 69 Pro (CTR69P)
All other models (69 WiFi, 69 Pro+, AI+, Outlet AI, Outlet AI+) are implemented in the code but could not be tested due to lack of hardware. Correct operation of these devices is not guaranteed.
Use at your own risk. No warranty is provided for functionality, accuracy, or fitness for any particular purpose. Any liability for direct or indirect damages is expressly disclaimed — including device failures, data loss, or system malfunctions.
The API reverse engineering and full understanding of the AC Infinity cloud protocol structure originate from the Home Assistant integration:
dalinicus/homeassistant-acinfinity
All credits for the API analysis and protocol understanding go to this project.
The entire ioBroker adapter code was implemented using Claude Code (Anthropic AI) and rewritten for the ioBroker platform based on the Home Assistant integration above.

- Install the adapter in ioBroker
- Enter the email address and password of your AC Infinity account
- Set the polling interval (minimum 10 seconds, default 30 seconds)
- Click Save & Close
The adapter automatically detects all connected controllers and creates the state tree under acinfinity.0.devices.<deviceId>.
| Mode | Behaviour |
|---|---|
| Off | Device runs continuously at offSpeed |
| On | Device runs continuously at onSpeed |
| Auto | Device switches based on temperature and/or humidity thresholds |
| Timer to On | Device turns on after toOnMinutes minutes |
| Timer to Off | Device turns off after toOffMinutes minutes |
| Cycle | Device alternates between ON (onMinutes) and OFF (offMinutes) |
| Schedule | Device runs daily between startTime and endTime |
| VPD | Device switches based on VPD thresholds (vapour pressure deficit) |
- Transition: The device gradually increases speed the further measurements deviate from the target. Each step changes fan speed by one level.
- Buffer: Creates a hysteresis zone around the trigger point to avoid rapid switching.
Adapter does not connect
- Check email and password in adapter settings
- Make sure the controller is online in the AC Infinity app
- Check the ioBroker log for specific error messages
State changes have no effect
- Check the log for API error responses
- Re-save the adapter instance to force a new login
- Check controller reachability (
info.connectionstate)
Sensor values missing
- CO₂, soil moisture and water level states only receive data when the corresponding UIS sensors are physically connected and synced with the cloud
- Fix: remove deprecated
common.titlefield from io-package.json (W184) - Docs: add manufacturer link to README (required for repository submission)
