After my Schlage Sense lock broke earlier this year I decided to do some research and upgrade. What did I pick??? – the August Smart Lock. Very much a bad decision on my part and I have been kicking myself for several months. I had the Sense lock for a few years and never really had any issues – something internally broke is the only reason for the change. I am pretty sure that the reason for the break is that the latch was pretty tight when locking and eventually the mechanism inside the Sense gave up. I chiseled out and filed the replacement plate and now the latch is smooth like butter. Definitely recommend the Schlage Sense Smart lock if you want something that work for HomeKit and just about everything else.
