About TimeMachine Viewer
Use TimeMachine Viewer to monitor the status of your basement or crawl space by connecting to a Time Machine Data Logger already installed in your home. Keep track of the temperature and relative humidity in your home, and look through historical data to make sure that your basement or crawl space is staying dry throughout the year. If the Time Machine Data Logger is hooked up to an UltraSump 4, you'll also be able to track the status of your sump pump, including how often it turns on and how many times it has been running on backup battery power.
