I have had my Aqara U50 lock for about eight months and I’ve had a couple minor problems with it. When I heard there was an opportunity to upgrade to a significantly more capable walk with a rechargeable battery. I jumped in this opportunity. The biggest thing for me as an apple user is UWB. I want to be able to have my kids watches or phones be able to unlock without having to put in a pin code.
I purchased the U400 last night and installed it this morning. I got it all set up and binded to my M3 hub. as well as set up in Apple home.
I truly love that not only does the battery have a USB-C charging port on it, but the real kicker here is the charging port on the bottom of the lock itself!
So I let the lock charge overnight from the bottom USB port, but it only reached 48%, I removed the battery and charged it for another hour and it got up to 89%. I am not sure if this normal or not.
I have also noticed a similar problem that my U50 was having where it was not “fully” locking. It looks locked but if I press on the knob it click into place. the U50 was way worse. I have a video somewhere. I am guessing the new beta for the “unleash motor performance” will help fix this.
I also got a chance to use the UWB unlocking this morning, and was VERY surprised how fast and responsive it was.
