INSTALLATION & CONNECTION
INSTALLATION METHOD #1
Tent Mount
Remove the tape cover from the iron plate and paste the plate on the INSIDE surface of your tent where you want the controller located. Then you can place the Smart Controller on the OUTSIDE surface of your tent where it will attach to the iron plate via a built-in magnet on its back.

* ① Iron Plate
* ② Smart Controller (with Magnet)
INSTALLATION METHOD #2
Wall Mount
This installation method requires drilling holes where you plan to mount the GrowHub Controller. First measure the distance between the holes on the iron plate and mark the distance on the mounting surface. Next, use a drill to create the necessary holes and push the plastic expansion pipes in. Then line the iron plate’s holes with those holes, and screw it into place using the expansion screws. Now the Controller can be placed directly onto the iron plate thanks to its built-in magnet!
You can also hang your GrowHub Controller directly on the screws without using the iron plate. First, measure a center distance of 74mm and drill an expansion screw on each point. Next, hang the GrowHub Controller directly on the screws by sliding the slotted hanging holes over the screws and then allowing the GrowHub Controller to hang down.

FAQS
Q: Can I use the GrowHub controller without connecting to Wi-Fi or the VIVOSUN App?
A : Yes, you can use your GrowHub controller offline or without the VIVOSUN App to control basic functions for LED lights, circulation fans and duct fans. However, after connecting your GrowHub to Wi-Fi, you can use the VIVOSUN App to visit your grow environment data remotely in real-time and to access more functions such as grow plan, historical data, and more detailed functions.
Q: How many components can I hook up to one controller?
A: For one GrowHub controller (E42/E42A), you can hook up 12 AeroLights (with RJ45 Daisy-Chain), 8 VS series lights (with RJ11 Daisy-Chain), 4 duct fans or clip-on fans (AeroZesh or others with Type-C), and 1 Temperature/Humidity sensor. Note: Some models of the VS series LED lights may support fewer daisy-chained lights. Mixing different models of VS series lights may lead to support of fewer daisy-chained lights.
Q: Can I connect more than one of the same type of equipment to my GrowHub?
(E.g., can I have two fans connected to two different outlets?
A: Yes. The App allows for more than one of the same piece of equipment (e.g., lamps, fans, lights) to be assigned to more than one outlet—usually, two outlets.
Q: How does the controller get power?
A: The VIVOSUN GrowHub Controller receives its power from an an Aerolight, an AeroZesh, and/or an AeroWave E6 through the control cable (RJ45 or Type-C). No additional power cable is needed. However, if you connect a GrowHub Controller to a VS series light (VS1000, VS2000, VS4000, etc.) or other compatible lights or duct fans without an AeroLight or an AeroZesh as well, an adaptor is needed to power the GrowHub Controller.
Q: What other components can I use with the GrowHub?
A: The GrowHub controller can support lights with RJ11 or RJ45 ports, and duct fans with Type-C ports. However not all devices (lights or fans) with those ports can be controlled with the GrowHub with complete functions, and certain devices may require an additional adaptor for the GrowHub. We suggest using VIVOSUN devices to connect to the GrowHub for complete functions and best experience. Please contact us for more information about third-party device support.
Q: Why can’t my VS1000 light be controlled by the GrowHub after connecting?
A: Please ensure your VS1000 or other VS series lights connect to the RJ11 port on the GrowHub controller with a standard RJ11 cable and switch the dimming knob to "EXT" on your VS light. If you connect multiple VS lights by daisy-chain, all the lights must be switched to "EXT".
Q: What kind of Wi-Fi router do I need? Is the VIVOSUN GrowHub compatible with 5GHz Wi-Fi networks?
A: The VIVOSUN GrowHub will connect to 2.4GHz Wi-Fi networks only. Most routers enable Wi-Fi networks for both 2.4GHz and 5GHz networks under the same name but with “2.4GHz” or “5GHz”, you need to choose the 2.4GHz Wi-Fi signal for the GrowHub during the pairing process.
Q: My GrowHub Controller does not connect to Wi-Fi when I pair it with my App, what should I do?
A: First, ensure the Wi-Fi network is 2.4GHz. The VIVOSUN GrowHub will connect to 2.4GHz Wi-Fi networks only. Next, please check whether the Wi-Fi network password is filled in correctly. If you still cannot finish the pairing process, please message our support email and provide the login email you use for the VIVOSUN App, so we can provide a tailored solution for you.
Q: What happens if my GrowHub Controller is oline?
A: If your GrowHub Controller is offline (i.e., no Wi-Fi connection or you do not have internet access), the controller will still operate using the last programmed settings or Grow Recipe. You can still operate the GrowHub directly on the Controller but you will not be able to control or read live data through the VIVOSUN App. The VIVOSUN GrowHub will connect to the internet automatically when your Wi-Fi connection is again available.
Q: What happens if there is a power outage? Do I need to reconfigure the Controller?
A: If your GrowHub Controller was connected to Wi-Fi and the VIVOSUN App before the power outage it will automatically reconnect to your Wi-Fi and continue executing your settings as if it had never lost power. If your GrowHub was not connected to Wi-Fi and the VIVOSUN App before the power outage, the time on the controller will need to be calibrated first, and the controller will run the previous settings automatically.
Q: Can I reset the VIVOSUN GrowHub for troubleshooting?
A: Yes, use a pin to press and hold the reset button on the controller (see page 7) for a few seconds until you hear a long continuous beep sound, then release it and the controller will be reset to the factory setting. All the settings including the Wi-Fi configuration will be cleaned.
Q: Can I reconfigure the Wi-Fi connection of the controller?
A: Yes. First, use a pin to press the reset button on the controller (see page 7). Then, reconfigure the Wi-Fi connection through the VIVOSUN App (see page 30-31).
Q: Why is the data shown on my App dashboard different from the data shown on the GrowHub’s screen?
A: The live data will update every minute. You can also slide the page down to refresh the data
Q: Can I temporarily override the settings while running a recipe?
A: Yes. You can temporarily override the recipe by changing to manual mode on the App or GrowHub controller. To override on the App, you need to stop the current recipe (Plan mode) before you change to the manual mode. To override recipe mode on the GrowHub, you need to unlock the recipe mode first.
Q: Does the app work with iPhone or Android devices? Tablets?
A: The VIVOSUN App can work on both iPhone and Android devices including Tablets. You can download the App in the Apple Store for IOS (iPhone or iPad) or Google Play for Android devices.
Q: Will the app alert me if there is an issue?
A: Yes. The VIVOSUN App will send notifications to your phone when devices have issues or environmental conditions are out of set ranges.
