March 14, 2012
- Added support for all modern web browsers. The Room Alert web interface should now be fully functional in all web browsers, including IE8/9, Firefox, Chrome, Safari, Opera and others that conform to modern web standards. With full support for Chrome and Safari, the web interface can now also be viewed in mobile devices running Android and iOS.
- Added support for the new ‘Push’ technology for use with Device ManageR. Previously, Device ManageR would query the device for sensor values at defined intervals. If the device was installed at a remote location, this could cause additional configuration steps because of firewalls that might be in place between locations. The new ‘Push’ technology allows users to configure Room Alert to proactively send sensor updates to Device ManageR at regular intervals. Since Room Alert will be sending data out to Device ManageR, firewall configurations can typically be simpler since outgoing connections are usually allowed. In addition, if Room Alert detects an alarm condition, it will immediately send an update to Device ManageR, regardless of the interval setting. This allows for more immediate notification of alarm conditions that is no longer tied to the Discovery Interval configured in Device ManageR. Please contact AVTECH for additional details about this exciting new feature.
- Updated the core embedded operating system and network drivers. This should improve the communication between our Room Alert devices and high end network switches to improve interoperability.

September 24, 2008
- Updated fields and labels on the Settings screens to be consistent across all screens and options.
- Added a timeout check to the SMTP sending function so a communication loss with the mail server does not cause the unit to stall while waiting for a response.
- Modified the SMTP sending function so it quits if authentication fails instead of continuing with an attempt to send an unauthenticated email if email authentication is enabled.
- Added support for displaying the ‘Heat Index’ value in Celsius in addition to the default of Fahrenheit.
- Added support for using a ‘YE’ parameter in addition to the default ‘OR’ parameter for controlling the Yellow/Orange LED on the signal tower.
- Modified the email format used when SNMP Traps are received to be more descriptive.
- Resolved an issue that caused Ping Alarms to always trigger a Red LED event instead of using the Alarm Options configuration.
- Resolved an issue that caused SNMP Trap Alarms to always trigger a Red LED event instead of using the Alarm Options configuration.
- Resolved an issue that could cause SNMP and TFTP functions to still respond even when configured as ‘Disabled’.
- Resolved an issue that caused the ‘Adjust’ value to be applied incorrectly when using the ‘Heat Index’ option on external Digital Temp/Humidity Sensors.

- Resolved an issue that could cause email messages to fail to send if the mail server responded with an alternative error code to the EHLO command. We now correctly fall back to using HELO if the initial EHLO attempt fails and returns a code other than the 250 ‘OK’ message.
- Added an ‘Uptime’ value to the ‘/getdata.htm’ output for future use as a way to determine how long the device has been powered on.
- Added an ‘Uptime’ value to the trace output for future use as a way to determine how long the device has been powered on.
- Added a new webpage display option designed specifically for mobile devices such as phones and PDAs that required a ‘Content Type’ to be passed with the page data. The new URL ‘http://(IP of Device)/mobile.txt’ will display a text only output of all current sensor data with a Content Type of ‘text/plain’. The URL ‘http://(IP of Device)/mobile’ will still display a text only output of all sensor data without the Content Type header.
April 9, 2008
- Resolved an issue that could cause sensor data to stop updating when both external digital sensors were connected for a period of time. The time to wait before reading new sensor data was increased to allow the larger amount of data to be received properly.
