I had an issue where a particular interface would lockup and I would not know HS was not receiving new data. Here is a very simple watchdog script to ensure devices are updating according to your schedule. This script looks at the last time a device was changed and reports if it occured in or outside the time window you set. Keep in mind the device value/status must actually change.

Run this in a recurring event as frequently as you like, and pass the parameters for device code and time window as noted below.

Suggestions for improvement are welcome! Thanks to other board members for code tips!

Code:
 
'Simple watchdog script to notify user when a device is not being updated in a certain period of time.
'Call using parameters for device code and time window in minutes, eg: ("Main","x50,60"), where x50 should
'be changed to the device code of your choice and 60 should be changed to the number of minutes to
'check since the device has been updated. In this example, the device is checked to see if it has been
'updated within the previous 'hour. Make sure to update your email addresses in the If block below.

Sub Main(Parm as object)

Dim LastUpdate as Date
Dim RefNum
Dim Device
Dim DeviceCode
Dim Parms() as String
Dim Mins as Integer 

Parms = Split(Parm.ToString,",")
DeviceCode = Parms(0)
Mins = Parms(1)

LastUpdate = hs.DeviceLastChange(DeviceCode)
Device = hs.GetDeviceByRef(hs.GetDeviceRef(DeviceCode))

If DateDiff("n",LastUpdate,Now) > Mins then
     hs.WriteLog("Status Watchdog", "The " & Device.location & " " & Device.name & " status has not been updated since " & LastUpdate & ".")
     hs.SendEmail("youremail@yourISP.com","youremail@yourISP.com","** HomeSeer Notice **","The " & Device.location & " " & Device.name & " status has not been updated since "& LastUpdate & ".")
Else
     hs.WriteLog("Status Watchdog", "The " & Device.location & " " & Device.name & " status has been updating normally.")
End If

End Sub
