XW-110™ WiFi Temperature Sensor Users Manual
Installation and Setup
2.4 Application Examples
The XW-110 can be configured for many different applications. Applications which require long battery
life require careful planning and setup. Four examples are described below:
Greenhouse Temperature Example
You wish to activate a warning light and receive an email if the temperature in your greenhouse
becomes too low or too high. No AC power is available.
Mount an XW-110 in a protected location inside the greenhouse. In this application the XW-110 is
workable with batteries because transmissions are infrequent. Use the bare air temperature sensor
which comes with the XW-110. Install a WebRelay™ or WebSwitch™ in your office and connect it to
your Ethernet network. Connect a warning light to the WebRelay. The WebRelay must be accessible
from your WiFi network and be assigned a fixed IP address. Your WiFi network must have adequate
coverage in the greenhouse.
First, the XW-110 must be configured to access your WiFi network. If no network profiles have been
configured, the XW-110 will automatically enter the access point mode and you can access the XW-110
directly with a computer or smart device with a wireless connection. If the XW-110 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-110 for the
stand-alone
mode. Configure the XW-110 to connect
to your wireless network. Navigate to the WiFi Networks tab and fill in the appropriate settings for your
WiFi 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 sensor tab. Enter the period with which the XW-110 should monitor the temperature as
well as the temperature thresholds for the alarm. To prolong the battery life set the update interval to 30
minutes or more. Set the remote relay action to
Turn On
. With this setting the relay will turn Off when the
temperature alarm condition is no longer met. Upon selecting an action, the remote relay options for
specifying the IP address, port, relay number and other options will show. Enter the IP settings for the
WebRelay. On the
Email Option
setting, select
Send email on High and Low Alarm.
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 contact your email provider for the exact settings to use. To provide
assurance the XW-110 is working, enable the
Weekly Status Email
option. Click the submit button at the
bottom of the page.
Once all the appropriate settings have been applied, click on the Reboot button, the XW-110 will reboot
and begin low power operation. The XW-110 will no longer broadcast an SSID and the web page will no
longer be accessible. The XW-110 will periodically awaken, measure the temperature and check for an
alarm condition. If an alarm occurs it will connect to your WiFi access point, activate the remote relay
and send an email message. Once each week the XW-110 will send an email with temperature and
battery information.
If you wish to change the alarm settings the web server must be re enabled. To enable the web server
press and hold the WPS button for 10 seconds. This will temporarily enable the web-server for 5 minutes
or until the unit is rebooted. You can access the control or setup pages during this time by entering the
IP address that was assigned to the device (http://xxx.xxx.xxx.xxx/setup.html) in the address bar of your
web browser.
