if node didnt send data for x

[n3roGit]

is it possible to add a function like:

"if a node didnt send data for X minutes then notify me"

I have a rule that says this:

if humidity of MBR Temp/Humidity was not updated for 1 hour then send mail to:\"xxx@vtext.com\" subject:\"MBR Heartbeat Alarm\" text:\"No Heartbeat\"

This is a good idea. But a connect-device like the battery device would be cool
