Take the guesswork out of greenhouse and indoor garden climate control. AC Infinity’s Smart UIS Controllers act like a central command center, automating your ventilation, lighting, humidification, and more based on real-time conditions like temperature, humidity, and VPD (vapor pressure deficit). They help stabilize your environment, reduce stress on plants, and keep growth more consistent day after day.
- Automate your climate: Devices can ramp up or down automatically as conditions change, instead of simple on/off control.
- One controller, multiple devices: Run multiple UIS devices with independent programming per port.
- Remote monitoring: Use the AC Infinity app to view climate data, set alerts, and adjust settings over WiFi/Bluetooth.
- Built for growers: Includes a 12-foot sensor probe for accurate, in-canopy readings.
Choose the Right Controller
All models help you automate temperature, humidity, and VPD control. The main differences are how many devices you want to control, and whether you want AI-driven automation (and optional CO2 monitoring).
| Model (Variant) | Best For | UIS Ports | Sensors Included | Automation Style | App & Remote Access |
|---|---|---|---|---|---|
| Controller 69 Pro (4-Port) | Smaller greenhouse zones, indoor gardens, starter grow setups | Up to 4 devices | Temp, Humidity, VPD | Programmed automation (dynamic triggers + schedules) | WiFi + Bluetooth app control |
| Controller 69 Pro+ (8-Port) | More devices, bigger greenhouse setups, multi-device control | Up to 8 devices | Temp, Humidity, VPD | Programmed automation (dynamic triggers + schedules) | WiFi + Bluetooth app control |
| Controller AI+ (8-Port) | Advanced growers who want AI-assisted stability and insights | 8 ports (expandable with splitters) | Dual-zone Temp, Humidity, VPD monitoring | AI-assisted automation that learns patterns to avoid spikes | WiFi + Bluetooth app control |
| Controller AI+ (8-Port) + CO2 Sensor Bundle | CO2-enriched growing, higher-performance environments | 8 ports (expandable with splitters) | Temp, Humidity, VPD + CO2 (bundle) | AI automation + CO2 monitoring and control support | WiFi + Bluetooth app control |
Tip: If you want the simplest upgrade from “manual greenhouse” to “automated greenhouse,” start with Controller 69 Pro (4-Port). If you’re running a multi-device setup or want AI-driven stability, step up to Controller AI+.
What Is the UIS Ecosystem?
UIS is AC Infinity’s connected platform that lets your devices work together as one coordinated system. Your controller becomes the hub, while UIS devices (fans, lights, humidifiers, heaters, and more) plug in and respond automatically to your climate targets.
That means you can keep your greenhouse or indoor garden in a healthier range with fewer manual adjustments, fewer swings, and more consistency.
How Smart Automation Helps in a Greenhouse
- Heat control: Increase exhaust or circulation when temps climb on sunny days.
- Humidity management: Trigger airflow and humidity tools to fight condensation and reduce disease pressure.
- Stronger plant performance: VPD-based control helps keep plants in a more ideal transpiration range.
- Time-saving: Scheduling, timers, and baseline minimum levels keep airflow and lighting consistent.
Simple Specs
- Measures: Temperature, humidity, and VPD (all models). CO2 included only with the AI+ bundle variant.
- Sensor probe: 12-foot probe for flexible placement.
- Mounting: Kickstand + wall-mount hardware.
- App control: WiFi (2.4 GHz) + Bluetooth (model dependent), with alerts, charts, and remote access features.
Frequently Asked Questions (FAQ)
Which controller is best for a greenhouse?
For most greenhouse owners, Controller 69 Pro (4-Port) is the easiest start, it automates ventilation, humidity, and lighting based on real conditions. If you’re running more equipment or want the most stable automation with AI insights, choose Controller AI+.
What does VPD mean and why does it matter?
VPD (vapor pressure deficit) helps describe how “thirsty” the air is for moisture. It impacts how plants transpire and absorb nutrients. When your environment stays closer to your target VPD range, plants generally handle stress better and grow more consistently.
Can I control multiple devices independently?
Yes. These controllers can run multiple devices and give each port its own programming, so your exhaust fan, circulation fan, and lights can follow different rules.
Do these controllers work when WiFi goes out?
Yes. Controller AI+ programming can remain active even if WiFi access is cut off, so your grow keeps running. (You just won’t be able to change settings remotely until the connection returns.)
Do I need the CO2 bundle?
Only if you plan to monitor or manage CO2 as part of your grow strategy. It’s most useful for higher-performance indoor grows or tightly controlled greenhouse environments. If you’re not adding CO2, the standard AI+ version is usually the better value.
What devices can I connect?
These controllers are built for AC Infinity UIS devices (fans, grow lights, humidifiers, heaters, and more), so you can automate them together as one system. Your exact compatibility depends on the device type and connector, but UIS is designed for integrated control.
Is installation hard?
Setup is straightforward: mount the controller, place the sensor probe, connect your UIS devices to available ports, then set your targets and schedules. Most people can get basic automation running quickly.
Popular Use Cases
- Backyard greenhouse automation (ventilation + humidity support)
- Seed-starting environments (steady warmth and moisture control)
- Indoor garden rooms (multi-device scheduling and triggers)
- Advanced grows (AI-assisted stability and optional CO2 monitoring)
