A:Answer I could tell you that you could install it yourself 30 mins top, don't need to pay for It. If you have an existing wired door bell push button at your front door, you are set, it is a simple replacement. I had an issue the hub or repeater has the wrong firmware so I'm doing a RMA. In my case the doorbell did not needed it I was able to add it to my home wifi just follow instructions included as the Wi-Fi signal is strong enough.
