Think about the level of Bizarre that being the CEO of Readit is anyway . That said his tampering is beyond wrong on many levels and makes me hesitate every time I touch the keyboard here . The words chilling and stifling come to mind . <| sep |> I had that door but the in wall version and was tired of replacing the collars at $ 30 each . I wired a button into each side of the door with the intention of training my dog to press it to open it , but we had to rehome the dog because my son was born and he was allergic so I never got around to it . It ' s not too hard to wire something in and have some sort of HA device activate it . The collar has a battery powered RF transmitter and there ' s a sensor on the bottom of the opening of the door . That ' s a little more complicated than I wanted to get in to hence the simple button activation . I had my door plugged in so a timer would be easy to set up . The door also has a battery operated mode , and you ' d have to wire a switch in there somehow if that ' s how you plan to power it .
