Hi Caseyapi,
You should just have to hit "Remove" on the Almond+, and then tap the switch on or off. Depending on it's distance, you may have to hit On/Off a few times for it to pick it up. If it's really far away, you may have to move the Almond+ closer to it, just to get it to sync.
But there's no special method of resetting these. You just have to Remove it, and then Add it.
