Imp commissioned, not appearing on planner

I was able to connect the impee and run the first helloworld program. I was trying the blink-o-matic program next. On planner, I must have accidentally deleted the node which had the impee. I’ve tried powering on/off the imp but it still does not re-appear on the page. 

Never mind, it’s working now. 

how did you get it to work? powering on and off?

to answer my question: yes

Actually i’m not too sure. I tried powering on and off again and it worked. The internet connection might have also dropped for a moment, 

If your imp was successfully commissioned, power-cycling should bring it back on Planner.
