Your network setup is now complete

Powering Down

The Minder Hydro can be powered down in two ways, via the Web Interface or with the button on the front

The quickest way is to simply hold down the power button on the front of the case for 3 seconds. The system will make a click noise and the button light will turn off. Please allow at least 30 more seconds for the computer to fully shut down before pulling the power cord out.

The other way is via the web interface, under System, you will see reboot and shutdown buttons. Enable the safety and press your choice, there will be no further prompts, the system will go offline immediately

Be warned if you you shut it down remotely you will lose access, it is highly recommended that you reboot your device only when you are in the same room as it. That way if there is a problem you will be there to unplug and replug it

The on board computer runs on very little power so if you are trying to hard reset it by pulling the plug out, allow at least 1 minute for all the power to drain before plugging it back in

Now that you have the Key and GPS locations entered press the ‘Update Weather / Test Settings’ button

weather test Hydroponic Grow           Box    Computer

If all the settings are correct you will see the connection status change to connected and will see some detailed information about the weather in your area.

Also the ‘Enable Weather Feed’ switch will automatically turn on if the connection is successful.

weather output Hydroponic Grow           Box    Computer

If you are successfully connected you can use this data as your Air Source by selecting the ‘Weather Feed is Air Source Switch’.

Enabling this option will tell the AI to ignore the Air Source/Outside sensor and use the temperature and humidity from the weather feed instead.

This is handy if your Growspace is too far away for your sensor to reach outside, if you have this option enabled you can remove the air source temperature and humidity sensor, as it is no longer used.

The weather will be checked every 5 minutes.

All ports are 12 Volt except for port 16 which is 24 Volt, and is intended for the humidifier

The Minder Hydro comes with red and blue LED  lights intended to be used as status lights

These are also handy for testing your DC jacks, use them in place of your devices by putting them into different ports for testing

Status Lights Led      control monitor computer automate

Each port on the rear of the minder is assigned to a device so ensure that you connect the right device to the right port

Port 8 is the water pump port and is also connected to the dial on the rear of the Minder Hydro.

You will need to turn the dial up to see your device work, and turning it all the way to one side with turn it off

12 volt connection explained Smart     Grow    Sensor Control

The power can be turned on and off in the ‘System’ dashboard.

In the ‘Power’ panel there is a 12V toggle option. When the power is off only the on board computer will continue to run, the sensor chip and all the devices will be down

The power supply has safeties built into it and will turn off if it detects a power problem

The ‘12V Power status’ indicator is independently verified from the power supply’s status signal

If power should be on but is not try disconnecting all devices and trying again

WiFi switches can be re-programmed to operate different devices as needed

mains to minder hydro Hydroponic Grow           Box    Computer

There is only one way communication that goes from the Minder Hydro to the wireless switch, the onboard computer does not receive any information back from the wireless switch so does not know its state

Regular status updates are sent to ensure that the WiFi switch is in the correct state

Before programming turn all devices back to 12V to prevent the system from accidentally sending out signals that might reprogram your device

When a WiFi switch is plugged in to a mains socket it enters a programming state, indicated by a flashing red light. It will do this even if is already programmed

If a transmission is sent while the device is in programming mode the device will be programmed to answer to that signal, you may end up with a switch that is both a heater and an AC

If you let the red light finish blinking it will then default back to its last programming

Flipping the switch ‘Enable Device Programming’, will allow you to start making changes, and a counter will start to when it resumes normal function.

wifi device program Hydroponic Grow           Box    Computer

Use the drop down to choose a channel, if there are two Minder Hydro units in the room make sure they are on different channels

wifi channel Hydroponic Grow           Box    Computer
Plug wireless switch into power plug (Switch’s light should be flashing) Press ‘Set as Humidifier’ (Switch should make a click noise and change from a flashing light to a solid light The WiFi Switch is now reprogrammed to be the Humidifier
Please note: You may need to press the buttons more then once, local interference can disrupt the wireless communication, keep pressing the button until you get a result

To reprogram a wireless device, plug it in and while the light is flashing you can press the ‘Erase Device Programming’ button to clear its programming and one of the set buttons to set it as that device

It’s important to erase a device before reprogramming it as it can be programed to be more than one thing at a time.

So if its programed to be the AC and you program it to be the heater it will respond to both signals

The ‘Erase Device Programming’ button sends a unique code that does two things It both turns off all the devices on that channel and it resets a wireless switch that is in a programming state back to blank, allowing it to be reprogrammed to another device

wifi device erase Hydroponic Grow           Box    Computer

Once you have erased your switch, please follow the programming a wifi switch steps above

Please note: You may need to press the buttons more then once, local interference can disrupt the wireless communication, keep pressing the button until you get a result
You can select what devices will be powered by the Minder Hydro and what will be powered by mains using the WiFi drop down menus Once a device is changed to WiFi the Minder Hydro will start sending wireless signals

Testing Devices

Please be aware the AI is running in the background and may be turning devices on and off interfering with your testing.

You may expect a device to be off but it will remain on due to the AI thinking its heating the room

For more rigorous testing please visit the ‘Test Mode’ guide to learn how to take direct control of the internal relays free from any AI control.

You can test your devices by plugging them into their assigned port then using ‘Device Control’ force the devices on and off.
