TTLock

I rely on remote locks to effectively run my short term rentals. Take it from me, this TT Lock is NOT something you want to invest in. Once you manage to get it set up, it will work fine, until it doesn't. If one small thing goes wrong with the gateway (let's say it gets unplugged, which happens occasionally), you won't be able to fix it without physically being present. You literally need to be next to the gateway and door lock, which is bad if you're halfway around the world?

I've used this app for two locks for about 3 years. Although slow and poor security, it has been fairly reliable. Recently it has been failing to connect to both of my locks via the internet and via Bluetooth. I get the impression it is not well maintained. There are several frustrating things about the user interface, but isn't too bad. It doesn't handle the locks being in one time zone, while I'm travelling in another time zone very well. It isn't the locks with the problem.

The app generally works okay, but there are some design issues that make its operation unnecessarily cumbersome. My main complaint is that when you add a new user/access code through the app, you have to also PHYSICALLY enter this same code once into the lock itself within 24 hours to "activate" it, or else it'll expire, which severely complicates remote access management. The app claims it's for "security reasons," but I don't see ANY extra security benefit here, just a useless limitation.
