I have a GMail account whose main purpose is to receive updates from an instrument deployed in a remote location. The updates are received 6-8 times a day, and they are normally "All is well", and I want to avoid having to check on it for when things are not.
The first bad scenario is when the update contains a
ALERT string, and so that's easy to solve: I have a filter that sends me an email if the update contains that.
The second is if the instrument dies or runs of battery, in which case the emails simply stop.
Can anybody suggest a method, using GMail's filters, IFTTT, to get an email notification when a GMail account has not received an email for XX hrs/days/etc? (this particular account only receives email from one source). I would strongly prefer to use an existing web service for this.
