It is hardwired and has power.  When checking app it shows a battery symbol that is red.  No voice communication is available.  Inside door bell will ring but it does not record.  Spoke with a Customer service rep and she said it was too cold.  I have had this door bell since 7/31/24 and it has been below 0  and it has always worked.  The door bell does not have a removeable battery.  Tried reseting it and still doesnt work.  Your suggestion was to wait until it gets warmer.  That is not an acceptable answer.  I do have the Protection package.
