"living lights are" shows up without clicking on the watch. "Living lights are off. Dining" shows up after swiping up the notification on the watch. The full message should be "Living lights are off. Dining lights are already off."
I didn't try autonotify though and think this short limit is due to the tasker notify method. I know for text messages, it shows almost six statements of "Living lights are off. Dining lights are already off." as just I tested it. This limit appears to affect the android notifications on my phone and watch the same.
Regardless, the real advantage to Android Wear is using google search/now to trigger Tasker Tasks and using Autonotify to create custom cards with pictures, buttons, etc... I don't think this is possible on the Gear 2 without developing, but could be wrong.
