Hi Sean
1.On your original point you must make then event detector with your 2 minute duration.
2. Then create a new binary virtual point.
3. go to event handler page and make a event handler like the picture. use the meta point that you created.

4. Now use <ma-get-point-value> on the new meta point and use that for your dashboard logic.
