I live in the U.S., my lock is installed on my front door, it is running firmware 3.0.0_0065, my thread network is setup by my Apple TV.Let me start with the good:*It was easy to install the lock itself*It could have been easy to install the keypad, my trouble cannot be blamed on Aqara (more on this later)*Works great with Apple Home after a good calibration*The fingerprint reader is snappy*Apple HomeKey, particularly with my apple watch, is snappy-- Keypad installation --I have brick all around my front door and because I would like to eventually hardwire the keypad to power like my doorbell, I did not want to mount it to the doorframe or to the door itself. The smallest masonry anchor screws I could find at Lowe's were too large for the keypad's mounting plate, so I made a wooden adapter mounting plate which I secured to the bricks, then mounted the keypad mounting plate to that. I do not fault Aqara for this, I only want others to be aware of it.-- Periodic Passwords --The idea of the periodic password is great, I really wanted to set one up... But if you restrict the days the password can be used on, the password doesn't work. I tried this on a Friday, with the latest firmware. I set the periodic password to be valid on Tuesdays and Fridays, any time of day, any number of times on those days, forever... Like I said, I tried this on Friday, the password should have been valid on Fridays, but the password did not work. If you set up a periodic password without any restriction on which days it can be used, it does work. I did not try any of the other restrictions to see if any of them work.-- Calibration --Aqara, your calibration and/or logic for determining locked / unlocked state need work... I should not have to "play" with the calibration procedure until I get it to work, and the lock should not (un-intentionally) get into a state where the motor is engaged and I have to force the thumb-turn to get it to disengage. Thankfully this did not happen to me while I was outside with my only way in being my key, I am not sure I would not have broken the key trying to unlock the door.-- Automatic Calibration --This did not work for me. The lock would never register that it was actually in the locked state. I could still use the keypad or Apple Home app to operate the lock (though because Apple Home always thought the state was unlocked, I had to flip it to lock then flip it to unlock to get it to actually unlock). But using the lock this way really isn't worth it. If you are having problems with automatic calibration like I did, you will have to install the Aqara app and attempt manual calibration.-- Manual Calibration --I managed to get this to work for me finally.... If I followed the directions and turned the thumbturn completely for the locked position and completely for the unlocked position I was having the same problems as auto calibration though not 100% of the time. I finally got this to work by "backing off" a bit from both the locked and unlocked states before continuing the manual calibration process. I still have trouble sometimes when using the thumbturn to lock the door with the lock not actually thinking the door is locked, but not the issues I had before. The keypad and using apple home to lock/unlock the door have been 100% reliable.
