For Future Reference this was the response that I received:
Sorry for the trouble. It’s possible that your power outage would have caused the router to be reset which could have caused the router to assign your TCP Gateway a new IP address. If that happened and the hub is unable to rediscover your Gateway due to the IP address change, unfortunately you’ll have to remove and reconnect your TCP bulbs from scratch.
The TCP integration was actually built by one of our community developers, so I’d recommend reaching out to the community forums to see if that is what happened:
But before you do, I’d recommend power cycling your hub and playing with the states of the bulbs from the TCP app. Then go back to the Things page to see if you can actuate the TCP bulbs from the SmartThings app.
