I bought a Yale smart lock with wifi august bridge connection for my rental unit. Have had troubles ever since. I have called support numerous times to no avail unless I am near the lock which I am not. The app does not work well, does not update, says I have wifi connected but the app does not update accordingly, and on top of it all I have had to replace the batteries twice and have only owned the unit for 3 months. At the rate I am going this is becoming more of a money pit than an ease of use for a rental.
