Update: The Wyze App must be at the home page and not at the lock setting page. For auto unlock to work, you have to exit the location radius of your home. Upon return, once you enter the location radius of home which is usually a city square block you have 10 minutes to get within range of your door. When you are within range of your door your bluetooth will tell the lock that you are there and the lock will unlock. Today I tested that out and rushed up to my apartment and lo and behold I heard my door whine and unlocked ceremoniously!!. I was surprised and delighted. To supplement my door lock, I bought the Wyze Keypad that is available in Amazon.com US with a shipping fee of 2x the price but at least I will have a keypad that is more useful to me when the lock locks me out of my apartment without a phone. Update again: the wyze app needs location services on all the time executing in your background apps and that uses up a lot of battery. My Wyze app had been on for 3 days straight and my iPhone ask if I would re-consider. I don't know the answer to this, but perhaps turn on location services for Wyze app before you leave home and turn it back off when you are home. The wyze app needs some kind of update so that we can pretend to go outside the location radius so just to trigger the app to unlock the door when you are within bluetooth range. I want a way to trigger the auto-unlock feature not only if you go away in a car and come back. I want a way to trigger the auto0-unlock even if I just take out the garbage and come back. Perhaps someday link it with some facial recognition camera or RFD hardware where you wave your watch against a sensor. Took one star off 5 stars because the app uses up my battery on location services on all the time. My previous Review: Smarthome products are so ubiquitous and you don't know what to buy. This is one of those products that we either automate first because you need to let someone in the house or it is something you automate last because you are a bachelor and you really don't need it. I am the latter. The nice thing about this product is that you don't need to replace the key portion of the lock meaning that since I live in an apartment the existing master key must work for the landlord, thus the first reason for buying this. I hate any kind of installation but this is as close painless as possible and Wyze promises you 15 minutes and yup it took about 15 minutes and it could have been quicker if I didn't pause in between. Take off screws from existing lock, pause, take off second plate from lock - it is a very old lock, pause, install wyze plate, pause, install wyze plate, pause, install batteries, plugged wyze hub in, press random buttons, didn't read manual, didn't install wyze app, press random buttons, read manual, install wyze app, followed instructions, hub installed, now the lock, followed instructions for lock, calibrated, oiled the bolt, re-calibrated. Done... with a long period of rest. I'm old, but it wasn't as bad of an install as I thought and the deadbolt slides super smooth now. Now about the auto-unlock, I realize that it is location based and I live in an apartment, yeah - no. I thought it would be some kind of proximity sensor thing? phone id? bluetooth? but if my door unlocks when I'm parking my car in the parkade, then no I cannot use auto-unlock for my apartment door. It was my 2nd reason that when I bring home the groceries and as I walked toward my apartment that the door would unlock (and open the door wide :-P). So where does that leave me as a bachelor? This doesn't even open when I'm in the parkade. I tried going out to my post office downstairs and coming back up and standing beside the door; Doesn't work!! So now what? do I return it? Do I keep it? I need a face id that recognizes my face then opens the door. I'll think about returning this useless thing now....
