Query: Just missing confirmation

This product is almost perfect. I use it to turn on and off a water pump that pulls hot water into our home system, so we do not need to wait minutes for the shower to get hot water every morning. This allows us to make a more responsible use of water.Product is in the garage close to water heater and I have remote by my bed in the second floor. I have used it for 2 months now and just once it did not turn on. It would be great to have confirmation in the remote that the product is on or off. This is the only reason to rate it 4.
