OpenFAN Micro Web UI

OpenFAN Micro comes with a built in Web UI and Web API.
In this section we will focus only on the Web UI portion.
In case you are looking for the Web API it has it's own page.

Web UI offers a simple web interface to control and get information from your OpenFAN Micro.
This interface can be accessed via web browser on your PC/Phone/Laptop/Tablet/etc.

Access Web UI

In order to access the Web UI of your OpenFAN Micro, you will need to know it's IP address and/or mDNS name.
Usually you can find this information on your network router or DHCP server (look for DHCP leases).

Just as an example, if we want to access Web UI of the OpenFAN Micro that has the following information:
- IP address 192.168.1.150
- mDNS name myopenfan

Using the above information, there are two ways to access the Web UI.

1. Via IP: In your browser open (navigate to) http://192.168.1.150
2. Via mDNS: If your network supports mDNS, in your browser open http://uopenfan-myopenfan.local

Accessing via IP address

Accessing the Web UI using device IP address should always work.
If you can't access the Web UI using devices IP address, double check that you have the right IP address.
If applicable, check that your network firewall is configured to allow access (TCP port 80) to OpenFAN Micro from your device.

Rename your device

You can assign a custom name to each OpenFAN Micro device.
This can be useful if you have multiple OpoenFAN Micro devices on the network.
This name will be used as device's network host-name and for mDNS.

To rename your device, open the WebUI and double-click on the device name in the bottom right corner.
The pop-up dialog will appear to prompt for a new name. Enter new device name and click OK to save.
After you change the device name, OpenFAN Micro will restart to apply new settings.

Device name and Web UI Access

Device name is also used for mDNS host name (as uopenfan-devicename.local).
If your device name is myopenfan and you are accessing the Web UI via http://uopenfan-myopenfan.local.
After you change the device name, for example to router.
You will then access the Web UI using http://uopenfan-router.local

Device Name Allowed characters

Please note that your device name must be between 3 and 12 characters and can only contain:
- A-Z characters
- 0-9 numbers

Device name is case insensitive

OpenFan, OpenFAN, OpEnFaN, openfan etc. are treated as the same name

Enable/Disable Activity LED

OpenFAN Micro has activity LED that blinks once a second to indicate activity.
You can enable or disable the LED blinking.

You can click on the "LED On" to enable the LED blinking.
Or click on "LED Off" to disable it.

Switching fan voltage (5V or 12V)

One nice features of OpenFAN Micro is that the same board can drive 5V and 12V fans.
And to do this you do not have to even touch the board (well you will have to swap the fan obviously).

In the Web UI you will see the Configure device section that has two buttons FAN 12V and FAN 5V.
You can click on either of them and it will change the fan voltage.

Is my board setup for 5V or 12V?

OpenFAN Micro has an LED that is labeled 12V.
If this LED is ON, board is configured to drive 12V fan.
If this LED is OFF, board is configured to drive 5V fan.

Fan Voltage

Note that selecting wrong fan voltage could potentially damage your fan.
It is recommended that you disconnect the fan before switching the voltage and also double check that you have selected the correct fan voltage before connecting the fan.
