Download the latest firmware for WatchDog-100 units. Each update is a complete firmware image, so there's no need to apply multiple patches in succession to update your unit from an older version to the latest one; just download and install the most-current version.

This firmware supports the following devices:

♦ WatchDog 100
♦ WatchDog 100-P

Note: As of version 1.5.0, the resolution of the WatchDog-100's internal analog-input channels has been increased to the full 10-bit range of the internal A/D converter chip.  To accommodate this change, the internal data-logging format was also changed.  If your WatchDog-100 is currently at a firmware version prior to v1.5.0, you will need to delete the log history after applying this firmware update, or the analog-input data will not be displayed and logged correctly!  If your logged data is important, please remember to download it from the unit before applying the newer firmware.


WatchDog-100 v1.5.5 — (released Sept. 22, 2014)

  • bug fixes:
    • ♦ Fixed an issue where some NMAP security scans were causing the unit to become unresponsive until rebooted.
    • ♦ Extremely low humidity (<10%) values from the sensor chip sometimes caused a math error when converting from the sensor's raw data value to a %RH value, which resulted in bad humidity readings in the log.  Fixed.
  • enhancements:
    • ♦ Default NTP sync period is now 43200 seconds (every 12 hours), rather than 1800 seconds (30 minutes) to reduce unnecessary load on NTP servers.
    • ♦ Changed the analog-input scaling messages on the Display page to clarify their actual usage.
    • ♦ Changed the description of airflow values on the RTAFHD3 sensor to better explain the sensor's behavior.

WatchDog-100 v1.5.4 — (released Oct. 11, 2013)

This is a mandatory upgrade for all users who are using Gmail as their SMTP mail server! (see below)

  • bug fixes:
    • ♦ Some customers reported problems with the RPM-X2 Remote Power Manager not graphing or logging Real or Apparent Power measurements correctly under certain conditions.  Fixed. Note: if your RPM-X2 data still does not show correctly after the update, clear the unit's log history, then close your browser and clear its cache.
    • ♦ Fixed an issue where SMTP servers that tried to force 2048-bit SSL client certificates (such as GMail), even when the WatchDog indicated to the server that it didn't support 2048-bit certificate keys, would crash and reboot the unit. WatchDog now supports 2048-bit keys.
  • enhancements:
    • ♦ Improved compatibility with some automated asset-management software (such as LanSweeper) that try to identify individual devices by sweeping the user's network looking for certain SNMP values.

WatchDog-100 v1.5.3 — (released Aug. 15, 2013)

  • bug fixes:
    • ♦ Fixed an issue where some versions of the RPM-X2 Remote Power Manager did not display the line-voltage reading correctly.
    • ♦ Email and camera passwords are now properly obscured in the configuration page's HTML code.
    • ♦ Fixed an issue where camera username/password settings did not always work properly when camera was set to use a user-supplied URL instead of one of the supported camera-model presets.
    • ♦ Fixed an issue where the unit would not accept email or NTP server addresses that had mixed numeric and alphanumeric parts in the domain names; i.e. ""
    • ♦ Fixed an issue where non-standard TLDs at the end of email addresses would not be accepted.


WatchDog-100 v1.5.2 — (released Feb. 19, 2013)

  • bug fixes:
    • ♦ Secondary temperature sensors on T3HD Temperature/Humidity/Dew Point Kit did not report below-freezing temperatures correctly.


WatchDog-100 v1.5.1 — (released Jan. 22, 2013)

  • bug fixes:
    • ♦ Added additional logic to insure that alarm thresholds associated with the internal analog-input channels are automatically rescaled to match the expanded 10-bit resolution after the firmware update is applied.

Note: Once the unit has been updated to firmware v1.5.1, it cannot be reverted back to an earlier firmware version.


WatchDog-100 v1.5.0 — (released Jan. 21, 2013)

  • bug fixes:
    • ♦ Fixed an issue where the clock would revert to 2000-01-01 if you updated the unit's firmware while the clock was not set, which could cause similar behavior as that described in v1.4.3, below.  Any date before 2010-01-01 is now considered invalid, and data will not be logged if the clock is set prior to that date.
    • ♦ Fixed an issue where if a sensor was disconnected while one of its alarms was tripped, and that alarm used the internal relay or a relay on the RPM-X2, the relay would "un-trip" on the first invalid sensor reading, then re-trip again when the sensor was declared "unplugged."
    • ♦ Fixed an issue which occasionally caused data logs to not be emitted correctly, making it look as though the unit's data was corrupted even though the data in memory was still intact.
  • enhancements:
    • ♦ Sensors which went "unplugged" due to signal interference or physical disconnection now send a "reconnected" message when they come back online.
    • ♦ Added support for new CCAT-60 type.  (Matching A/D converter for 60VDCM analog sensor.)
    • ♦ Increased resolution of the analog-input channels to use the full 10-bit capacity of the internal A/D converter chip.


WatchDog-100 v1.4.4 — (released Nov. 14, 2012)

  • bug fixes:
    • ♦ Trying to view the Logging-page graph when there was no data in memory resulted in an empty black square on some browsers.
    • ♦ Unit would sometimes return malformed SNMP packets when attempting SNMPGetNext on a nonexistent or invalid OID.
    • ♦ Fixed some MIB syntax issues which caused certain SNMP management software to fail to import the MIB correctly.
    • ♦ Some OIDs associated with the T3HD sensor device were returning incorrect data types.
  • enhancements:
    • ♦ Added D-Link DCS-6112 camera to supported camera list
    • ♦ "Clear Log History" now requires the user to be logged in at Control or Admin levels if a Control password is set.
    • ♦ More informative error message if user tries to set out-of-range alarm delay or repeat intervals.
    • ♦ ~ and ^ characters now allowed in e-mail addresses.

WatchDog-100 v1.4.3 — (released Sept. 24, 2012)

  • bug fixes:
    • ♦ All graphing/logging functions are now completely disabled if the clock date is invalid. This fixes an issue where the unit sometimes tried to log data points after the unit had been left powered down long enough for the internal clock's backup power to run down, which caused excessively-long download times on logs and graphs due to the unit trying to fill in the gap from Jan.1st, 2000 to the current date with empty data cells whenever the log data was requested by the browser.
    • ♦ Fixed some issues with malformed or invalid URLs on certain camera models
    • ♦ Fixed an SNMP issue with traps not having the correct instance numbers when a unit had more than one of the same type of external sensor attached.
    • ♦ Fixed an SNMP issue where CCATs were being assigned instance numbers based on their matched analog-sensor type ("water", "smoke alarm", etc.), which could potentially result in two CCATs of different types being assigned the same instance number, making one of them effectively "invisible" via SNMP.
  • enhancements:
    • ♦ SNMP v2C traps generated by alarms associated with CCATs now specify the CCAT's "sensor type" OID as part of the trap message.
    • ♦ Access, camera, and SNMP e-mail passwords can now be up to 39 characters long (previous limit was 19 characters).
    • ♦ Gaps in the data log are now shown as empty spaces on the graph, instead of being graphed as "0".
    • ♦ Made the Logging page graph larger, for better visibility on handheld devices.
    • ♦ Automatic time-range adjustment on logging page now allows the user to choose the largest time range that will display *all* of the data in memory, not just the largest range that can be completely filled by the available data. (For example, if there were 5 hours' worth of data in the log, the user can now choose the 8-hour range and the "extra" 3 hours will be shown as a blank gap, whereas previously the unit would only let the user choose the 2-hour range because there wasn't enough data to completely fill an 8-hour graph.)
    • ♦ Various minor UI and browser-compatibility improvements.

WatchDog-100 v1.4.2 — (released Aug. 10, 2012)

  • bug fixes:
    • ♦ Fixed an issue with ':' character not being allowed in UTC Offset field even though "nn:nn" is a valid offset-time format
    • ♦ Fixed an issue with alarm repeat and delay parameters not being saved correctly when user entered excessively-large times in these fields
  • enhancements:
    • ♦ Admin Info:Contact Phone field added to web-page footer, next to Contact Name/E-mail link.
    • ♦ Contact Phone field now allows users to specify phone numbers with extensions, or non US-style phone numbers.

WatchDog-100 v1.4.1 — (released Aug. 6, 2012)

  • bug fixes:
    • ♦ Fixed an issue where long email addresses could cause the unit to fail to migrate its configuration data from v1.3.x to v1.4.0, resetting the unit to factory-defaults

WatchDog-100 v1.4.0 — (released Jul. 31, 2012)

  • bug fixes:
    • ♦ Temperature-offset control now applies the appropriate correction to relative humidity as well
    • ♦ Fixed a logging issue caused by disconnecting sensors without clearing the log
    • ♦ Navigation menu has been changed back to static instead of floating
    • ♦ Other minor fixes
  • enhancements:
    • ♦ Added support for the THD, T3HD and RPM X2 sensors
    • ♦ Alarms now support delay and repeat times like the WeatherGoose-II series
    • ♦ Number of e-mail recipients has been expanded from 3 to 5


Note: Once the unit has been updated to firmware v1.4.0, it cannot be reverted back to an earlier firmware version.


WatchDog-100 v1.3.3 — (released Apr. 10, 2012)

  • bug fixes:
    • ♦ corrected SNMP MIB data types for internalRelayState and internalAvail
    • ♦ SNMPv2 var-bind doesn't always return correct OIDs

WatchDog-100 v1.3.2 — (released Mar. 1, 2012)

  • bug fixes:
    • ♦ Extraneous .0 was appended to certain OIDs requested by an SNMP-Get
    • ♦ Invalid response on GetNext for particular OIDs
    • ♦ Minor corrections to MIB

WatchDog-100 v1.3.1 — (released Jan. 9, 2012)

  • bug fixes:
    • ♦ An issue sometimes prevented user accounts from being set.
    • ♦ SNMP Get requests for extra-long OIDs could lockup SNMP service.
  • enhancements:
    • ♦ Minor changes including the navigation bar now scrolls with the page.

WatchDog-100 v1.3.0 — (released Dec.21, 2011)

  • bug fixes:
    • ♦ SMTP timeout period was too short for some servers.
    • ♦ Unexpected negative values in certain measurements, such as dewpoint, resulted in abnormally-high values being stored in the log.
      Note: if you have experienced this problem, ITWatchDogs recommends that you erase the unit's logged data before applying the v1.3.0 update.
  • enhancements:
    • ♦ Logged data can now be viewed as a graph on the logging page.
    • ♦ Log data can be downloaded in JSON (JavaScript Object Notation) form, as well as CSV.
    • ♦ Improved user-input checking, with more helpful error messages for invalid entries in configuration fields.


Note: ITWatchDogs does NOT recommend downgrading units running firmware v1.3.0 (or higher) back to an earlier 1.2.x version. Doing so may cause the unit to lose all of its user settings and revert to factory defaults, or may require the unit to reset via the IP RESET button.


WatchDog-100 v1.2.0 — (released Sept.12, 2011)

  • bug fixes:
    • ♦ Alarm thresholds set on the analog-input channels did not behave as expected when using a user-defined scale with negative values
  • enhancements:
    • ♦ Increased SNMP community string lengths to 16 characters
