A:AnswerJack,
I would recommend calling the customer service number at 1-800-988-7973 and asking them them your question. They are open from Monday through Friday 9 AM to 5 PM.
A:AnswerThere is about a 3 to 5 second delay. That is also depending on your wifi and your cell provider. So not sure if you would consider that “real time”.
A:AnswerNot sure what you mean by 5G wifi. If you mean does it work with your phone data plan when you set your phone up as a hot spot, I suspect it does but I am not sure. It works well with ordinary home internet.
A:AnswerNo. It does not connect with HomeKit. After doing some research, it seemed they tried to a while back and it never panned out. It doesn't seem like they plan to add HomeKit functionality either.
A:AnswerI don't know if this one is specific to BestBuy, but it also takes an included micro sd card that plugs into the chime hub. It comes with a 16Gb micro SD card.
