August Wi-Fi Smart Lock Silver

I've had the lock installed for close to two years, and it works very well, and integrated flawlessly with Alexa for voice commands and routines. My favourite feature is the auto-unlock. The lock opens when I'm walking up to the door. I don't use the auto-lock feature, however it is available. The lock installs on the inside of the door, and is 'renter friendly'. I needed only a screwdriver and an extra pair of hands. I purchased rechargeable batteries, and the app alerts when batteries need to be changed. My lock is on the exterior door of an unheated entryway, in Canada, and rhe lock worked well for the past two winters, (with more frequent battery changes). I have given custom entry permission to family and a pet sitter. The pet sitter is scheduled to be allowed entry on certain dates during certain times. My son is always allowed entry.
