  Yes, but it is a little more technical.

  1.) Build a workbook that e.g. uses the standard deviation function to identify if there is a trend change. You will find further documentation under Executing complete standard deviation analytics and GROUPSTDEVS.
  2.) Your last sheet in the workbook should output something like “Change” or “No-Change” - use the IF function to get there.
  3.) Run your workbook on a schedule e.g. every hour.
  4.) Use the Rest API to load the very latest result of the latest sheet to identify if there is a change or not. This is described in Accessing Datameer Using the REST API.
  5.) Use any kind programing language or a tool like Nagios to send you email, text message or similar to get the alert.
