No updates available.

Current software version: 1.0.0

Firmware updates should only be applied over a local network connection.

Note: Firmware updates require the Java runtime available here: http://www.java.com/en/download


Connection to Network

Installation requires connection to your network router or switch which supports 10Base-T Ethernet. Connect the built-in ethernet port to your network device using the included cat-5 cable or a standard cat-5 networking cable of your choice. You may also use a wireless bridge or a Powerline network device to provide the network connection. The 1-Wire Temperature Monitor & Email Notifier device will obtain an IP address automatically via DHCP.

Connection to Power

Connect the included power adapter to the device and plug it into a standard wall outlet. When plugged in, the green LED on the ethernet port will blink for 5 seconds and then the device will boot normally.


You can connect up to 32 1-Wire temperature sensors and the values will be updated approximately every 30 seconds. Attach the screw terminal adapter to the RJ45 port marked 1-Wire for easy connection to your 1-Wire sensors. The following sensors are supported: DS1822, DS1825, DS18B20, DS18S20. You must power your sensors from the supplied 3.3V Output on pin 7. A strong pull-up for parasite-power devices is not provided, but they have been tested and should work under most conditions. If your 1-wire network is subject to surges due to lightning or other discharges, additional protection circuitry should be used.

1-Wire Pinout

The pinout of the RJ45 1-Wire connection is described below. When looking at the connector with the tab side down, pin 1 is on the left and pin 8 is on the right. Obey the "Do Not Connect" pins as they have other functions internally.

Pin 1 - 1-Wire Data
Pin 2 - 1-Wire Data
Pin 3 - Do Not Connect
Pin 4 - Ground
Pin 5 - Do Not Connect
Pin 6 - Do Not Connect
Pin 7 - +3.3V Output
Pin 8 - Do Not Connect

Web Interface

To access the web interface type 'http://onewire' into your browser. This may not work with all routers and network configurations (see below hint). You can also type the IP address of the 1-Wire Temperature Monitor & Email Notifier device which can be found in your router interface by matching an IP address from the table with the MAC address printed on the bottom of the device or by using an IP scanner tool to search by MAC address. Log in using the username 'admin' and the default password 'admin'.

Windows Hint: In your network connection properties under TCP/IPv4 properties, click the advanced button. In the DNS tab, select "Append these DNS suffixes (in order)" and click add and enter "." (a single period with no quotes).


This page shows the IP address, MAC address, firmware version, time as kept by the 1-Wire Temperature Monitor & Email Notifier device (adjusted for your computer's timezone settings) and displays the basic status information for the device.


This page displays the detailed configuration for each sensor and its alerts.

Email Subject
Set the subject for the email alert. (31 chars)
Email Message
Set the message for the email alert. (140 chars)
Special Values (message only)
%%D - date (mm/dd/yyyy)
%%T - time (hh:mmAM/PM)
%%d - day of the week
%%t - sensor's temperature value
%%L - sensor's text label
%%N - sensor's number
Example Message: %%L value is %%t
Resulting Alert: Sensor 1 value is 74.0 deg F
Periodic Alert
Enter a value specifying the number of minutes between periodic alerts. An alert will be sent including all sensors at this interval. Enter 0 to disable.

For each sensor, enter the low temperature limit in the box marked L. Enter the high temperature limit in the box marked H. When the temperature value measured by the sensor crosses this boundary an alert will be triggered. The alert will be sent once and will not be reset until the sensor temperature is 1.5 degrees lower than the upper limit or higher than the lower limit. This is intended to prevent lots of alerts due to small temperature fluctuations.


This page will display a list of all the currently connected sensors and their current temperature readings. Sensors are polled approximately once every 30 seconds. Refresh the page to update the readings.

To recognize new devices, click the Device Search button. New devices will be listed as they are found (page refresh may be required). To change a device's text label, click on the device name.

To erase the device database, click ClearDB. This will erase the record of all stored devices.


This page allows you to adjust various general and email settings.

You can enable or disable daylight savings time (DST) and change the admin password. Password fields are limited to 15 characters or less.

Below, you can enter the settings for the email server and account that is used to send the email alerts.
