There are several cases when iDevices product you're trying to pair to does not have the Bluetooth signal strength to complete the pairing to your Instant Switch.
If this occurs, move the Instant Switch to a new location closer to the product you’re trying to pair with and attempt to pair again. If the new location doesn’t resolve the pairing issue, there may be objects in-between the product you’re trying to pair with the Instant Switch causing decreased Bluetooth signal strength. Items such as walls, doors, and refrigerators are a few examples of items in the home that can cut down the Bluetooth signal. To test if this is the cause, attempt to pair the Instant Switch directly next to the product you’re trying to pair with. Once it pairs, move the Instant Switch to the desired location and see if you’re still able to control the product. If you are unable to control the product from the Instant Switch it means the location is too far or the signal strength is being decreased significantly by items between the products.
