Hi guys.I have a Chime Pro 2nd gen to extend range to the cameras in my garden but I need to go further to purchased a second chime pro 2nd gen but how do I connect that to the first chime pro as it is not an option I see any we here.Or is it simply a case of when selecting the initial WiFi name which is my previously used one is this connecting via the chime pro which is in between my router and this 2nd unit?Need to install a device further away which is why I purchased the second chime pro 2nd gen so I could get a signal.Thanks.
