Accidentally Removed Sensors

While intending to add some new window sensors I accidentally removed the existing sensor list. Can I get assistance reprogramming?

Panel settings are periodically backed up on Alarm.com. I have pushed a backup list of sensors as they were (just to make sure another backup does not run after you have removed the sensors). Make sure your panel does not lose power during this time.

Can you verify in a short while whether this was successful?
