Bookmark your WHF controller

There are a couple of ways of quickly accessing your whole house fan controller through a web browser.

A bit of technical background:

Your AirScape WHF gets an IP address (something like 192.168.xxx.xxx) from your router through a process called DHCP.  This IP address stays the same for long periods, but  may change because of power failures, unit resets, etc. For convenience we don’t want to have to look for that IP address or URL whenever we want to change fan speeds or set the timer.

Method 1: Fix the IP address or set an IP address reservation

  • Follow the instructions to reserve or fix an IP address as described in http://blog.airscapefans.com/archives/ip-address-reservation
  • Put the IP address into your browser URL window
  • Save that page as a Bookmark

 

Method 2: Use the AirScape server to find your IP address

  • You need to be signed up for the AirScape Data Monitoring. (Call us to set this up)
  • Make a bookmark on your browser with the address as follows: http://airscapefans.com/control/local-link.php?mac=:last-6-characters-of-your-MAC . You can find the ‘last-6-characters-of-your-MAC” on the sticker of your WHF control panel. This one (pictured below) has a MAC address of 60:CB:FB:00:00:17.
  • The bookmark for this example would be: http://airscapefans.com/control/local-link.php?mac=000017
  • This will only work when you are connected to your LAN (local area network). So if your smart phone is not connected to your home LAN, it won’t work.

Whole House Fan Monitoring

monitoring-line-drawing

What ? The  data monitoring package “DMP” is a new feature available for AirScape whole house fans. This package of extra sensors and software allows whole house fan owners to view room, outside, and attic temperatures. Users can view the temperatures through their browser enabled devices (smart phones, computers, tablets …). Historical data will be saved on AirScape servers and will only be available by secure login.

Why is this cool ? You will be able to check temperatures in your house, attic, and outside remotely. By looking at the graphs of temperatures, you’ll be able to decide on the best ways to save utility costs. Upcoming software will be able to total your annual energy savings.

When? Available in the next 2 weeks on select models.

Cost ?  The additional cost for the 3 temperature sensors (accurate to 1 deg F) and additional embedded software will be $49. Monitoring and web access: FREE

Privacy ? Your data  will only be available to you, secured by encrypted passwords. Aggregated data that does not reveal the user’s identity may be used for research purposes.

Inside the new controller

We thought that you’d like to see all the cool stuff that makes up our new controller.

Of course, we had to have a microprocessor. A microprocessor controls all the sequencing and logic. It also does a lot of work serving up web pages and communicating with the switches, remote controls, and motor.

Optoisolators provide protection against stray (or man-made) voltages.

The Clock crystal gives us a “tick” every 1/32,000,000 th of a second. That’s the basis  for all timing functions.

A programming port – that’s where the programmer downloads his program for the 50th time after a series of mistakes  🙂

Relays are electrical switches (listen to them click) that control higher power loads (like the door actuators) that would burn out a microprocessor if connected directly.

 

 

IP address reservation

This applies to our 2nd Generation controls (shipping with 3.5eWHF and 4.4eWHF models as of July 2012) that are connected to a home network (LAN).

Every device that communicates with an IP (internet protocol) network will have an IP address (local area network addresses will often be something like 192.168.xxx.xxx) and a MAC address. MAC addresses are the serial numbers of the internet and are registered with the IEEE (institute of electrical and electronics engineers). AirScape has a block of MAC addresses that will always be of the form 60:CB:FB:xx:xx:xx . This makes it very easy to find and identify your AirScape whole house fan when it’s on your network.

The AirScape control board gets its IP address from your router through a process called DHCP (dynamic host control protocol).  When your router senses that a new device is connected, it assigns an IP address to that device. (It know that the device is ‘new” by its MAC address – every MAC address is different).

Now, here is the whole point of the IP address reservation. A DHCP assigned IP address can and will change, but we want a fixed address.  The IP address reservation provides the best of both worlds. There is no IP address configuration at the device. The router will recognize that device by its MAC address and then assign it the same IP address each time.

The following example and screenshots are of a D-link DIR-825 router.

Note the AirScape MAC address

It’s marked on the electrical box cover and in this case, it’s 60:CB:FB:00:00:17

 

Add DHCP Reservation

We can pick any IP address within the LAN range (192.168.0.1 to 192.168.10.255) with the exception of already used addresses. In this case, we are selecting 192.168.0.13
