  WebIO Internet connects Wireless Temperature Sensors

WebIO Version 3 with Wireless Temperature Sensors

WebIO v3 allows you to read wireless temperature sensors located in your home or office, indoors or outdoors, from over the Internet via WebIO's internal web pages and/or PC monitor/notification software. If you ever wanted to be able to check the temperature of your vacation home while your away, from over the Internet, using your cell phone or computer, WebIO v3.5 lets you do that. Using three wireless sensors you can now read the temperature and humidity of your garage, basement and main floor all from the WebIO webpage.

When using WebIO with the WebIO-TM PC software on local or remote PC you can monitor, notify and configure control automation on more then 10 wireless sensors. This allows you to set temperature thresholds for sending email and SMS/text alerts and set automatic control of X10 connected devices such as air duct fans and lamps based on temperature thresholds.

This new WebIO model includes all the X10 control features of WebIO version 2.2. with the addition of a wireless receiver for reading of wireless temperature sensors. Note: WebIO Version 3 does not have an LCD display as does version 2.
Version 3.3 also provides the additional option of using an external wireless X10 transmitter as an X10 transceiver or using any one of the Powerline X10 transceivers supported by version 2.2.

WebIO version 3 features: 
  • Easy to install, no PC required for core set of features, embedded device reliablilty
  • Embedded Web server providing web page interfaces for remote Internet access via PC or cell phone, Smartphone
  • Web interface for X10 control and query features of version 2.2
  • Internal webpage support for 3 wireless temperature sensors, plus 1 internal temperature sensor
  • Support for more than 10 wireless sensors when using the WebIO-TM PC software
  • Email and SMS/Text notification and control automation based on temperature thresholds using the WebIO-TM PC software
  • Support for wireless X10 transmiter (Firecracker) with special cable. (when used, replaces X10 powerline controller)
  • CGI programs supporting your own external web sites using HTML, Javascript, AJAX, etc. Version 3.3 adds CGI for temperature sensors

  Wireless Temperature and Humidity Sensors

Wireless Temperature and Humidity Sensors

WebIO v3 receives from Oregon Scientific brand wireless sensors which can be purchased from on-line stores or at local stores such as Target, Best Buy and Radio Shack.

WebIO v3.3 supports sensors of the models displayed and more.

Other Oregon Scientific temperature and humidity sensors that transmit at 433MHz may also work with WebIO v3. OS 10 channel sensors are not supported.
Sensors from other wireless sensor manufacturers do not work with WebIO. (such as sensors from Springfield or La-Cross)

Oregon Scientific also packages sensors with receiver display units.

  WebIO Wireless Temperature Webpage

WebIO web page for temperature sensors

The image above shows the WebIO v3 Temperature Sensor Page. This page displays the internal sensor and up to 3 wireless temperature and/or temperature and humidity sensors.

Each wireless sensor can be assigned a name such as shown above. Temperature reading is displayed in degrees Fahrenheit. Sensors that also provide humidity will display a humidity % value.

Each wireless sensor is designated a channel number of 1-3 using a small switch in the battery compartment. Upon sensor battery installation an sensor identifier is generated. In the case where sensors are assigned the same channel, they are still differentiated by ID. This can happen where a neighbor also has a sensor designated with the same channel number as your own sensor.

When WebIO receives a wireless sensor reading, the sensor's status is updated with a number of 255. Over time this number decriments but is refeshed to 255 upon each sensors wireless reading. This gives an indication of time passed since last reading, such that if a wireless sensor reading is not received over a long period of time the status will lower and could eventually become a value of 0, indicating that the last know reading is old. (where a value of 0 indicated several hours since last reading).

WebIO v3 Wireless Temperature Sensors

WebIO contains a 433Mhz wireless receiver and software protocol for receiving from Oregon Scientific wireless temperature and humidity sensors. Although more then three wireless sensors can be used, the sensors are limited to three channels (1-3). If you have two or more sensors on one channel WebIO's webpage will only display the most current sensor reading from each channel. The sensors that work with WebIO v3 are listed above, although more may work but have not been tested/found to work with WebIO.

WebIO v3 Wireless X10 Transmitter

WebIO works with various X10 powerline transceivers such as the Powerlinc, PSC05/TW523 and XM10. WebIO v3.3 will also work with the very low cost Wireless X10 Firecracker transmitter model CM17a. This requires a special cable (RJ12 to DB9 cable) that allows plugging in an external Firecracker to the WebIO X10 interface connector (RJ12).
The Firecracker then requires an X10 wireless receiver such as the TM751 or RR501 to transmit the Firecracker Wireless signals onto the powerline.
The Firecracker is a transmit only device. This does not allow WebIO to get a status response from 2-way X10 devices such that WebIO cannot query X10 devices. The Firecracker as a WebIO X10 interface can provide a very low cost form of X10 control and be useful to work around problems with a WebIO installation having direct access to AC powerlines.

WebIO v3 PC Software

WebIO v3.5 comes with the WebIO-TM PC software that will monitor temperature sSensors via WebIO's new UDP network interface. (a CGI interface is also available for developing your own apps) WebIO-TM allows you to be sent temperature low and high thresholds per wireless sensor. This alows for alert notification via email and SMS/text message. For example: This can allow you to receive an email notification when a wireless temperature sensor intalled at your lake home has had a low reading of less then 40F degrees.
WebIO-TM software allows for X10 control automation on the same temperature sensor thresholds. For example: This allows for automating a solar thermal panel air duct fan controlled by an appliance module to come on when a specified wireless sensor temperature goes above 90 degrees Fahrenhiet and turn off the fan at below 70 degrees.
