Installation and Setup
2.4 Application Examples
The XW-111 can be configured for many different applications. Applications which require long battery
life require careful planning and setup. Several examples are described below:
Storage Shed Door Example
You want to receive an email whenever someone opens the door to your storage shed. The storage shed
is within range of a Wi-Fi access point. No AC power is available.
Install a magnetic door switch sensor and connect it to an XW-111. In this application, the XW-111 is
workable with batteries because transmissions are infrequent. For best battery life, the magnetic door
switch should be wired such that when the door is closed, the switch is open.
First, the XW-111 must be configured to access your Wi-Fi network. If no network profiles have been
configured, the XW-111 will automatically enter the access point mode and you can access the XW-111
directly with a computer or smart device with a wireless connection. If the XW-111 has been previously
configured for other uses, press the Access Point button. Scan for, and attach to the XW110-XXXXXX
wireless network. Access the setup pages with the following URL: http://192.168.1.2/setup.html
For this application, configure the XW-111 in stand-alone mode with the internal web server disabled.
Configure the XW-111 to connect to your wireless network. Navigate to the WiFi Networks tab and fill in
the appropriate settings for your Wi-Fi network. Obtain the IP address from your network administrator.
To increase battery life, disable the HTTP web server and avoid using DHCP. Press the Submit button at
the bottom of the page.
Navigate to the Inputs tab. On the Email Alert setting, select Send email when Input On. You may also
want to set the Email Deadband option to 5 seconds. This will prevent multiple emails from being sent if
the switch opens and closes multiple times as the door is opened. You will receive an email the moment
the door is opened, but no more until at least 5 seconds has elapsed and the switch were to close and
open again. Change the Module Description text to a descriptive name such as "Storage Shed." This text
may be up to 35 characters long and appears on the Control Page and in email messages when email
alerts are enabled. Change the On Status Text to "Door is Open." Click the Submit button at the bottom
of the page.
Navigate to the Email tab and enter the SMTP server settings as well as the username and password (if
required). You may need to search online for your email provider's exact settings to use. To provide
ongoing assurance that the XW-111 is working, enable the Weekly Status Email option.
Once all the appropriate settings have been applied, click on the Reboot button. The XW-111 will then
reboot and begin low-power operation. The XW-111 will no longer broadcast an SSID and the web page
will no longer be accessible. If the door is opened, the XW-111 will awaken, connect to your Wi-Fi access
point and send an email. Once per week, the XW-111 will send an email with input state and battery
information.
Door Bell Example
You want to activate a buzzer to indicate someone has pressed a call button at your warehouse door.
The door is within range of a Wi-Fi access point. No AC power is available
The XW-111 is workable with batteries because transmissions are infrequent. Install a WebRelay™
anywhere in your facility and connect it to your Ethernet network. Connect a buzzer to the relay contact.
The WebRelay must be accessible from the Wi-Fi network and be assigned a fixed IP address. Your Wi-
Fi network must have adequate coverage in the warehouse. Connect the call button to the XW-111 and
mount it indoors near the door. For best battery life use a button with normally open contacts (NO).
For this application, configure the XW-111 as a stand-alone device with the internal web server disabled.
Configure the XW-111 to connect to your Wi-Fi network as explained in the previous example.
