This was my 2nd august smart lock, the first was a V3 and it had its issues at the beginning.  I replaced my door and it no longer fit.  I bought the V4 WiFi and its a gorgeous piece of hardware.  WOULD NOT CONNECT TO MY WiFi because my router wont allow me to have different network names on both 5ghz and 2.4ghz, A HUGE SHORTCOMMING. Had to send it back.  Very disappointed.
