5.0 out of 5 stars Use whichever adaptor that puts the notches at 12/3/6/9 o’clock
Reviewed in the United States on August 1, 2023
If you had asked me yesterday I would have given this lock 2 stars. Been living with it sorta connecting and auto locking or unlocking one time and then not re-syncing the status in the app for almost a year. Tried perfecting the latch so it was smooth and didn’t catch AT ALL for a good while and that wasn’t the issue. We tried getting a better WiFi signal, disabling all the battery draining features/notifications, calibrating the lock, restarting the app etc. Sometimes it would work a couple times and then resume not syncing on the app. The WiFi connection was strong, the log would note the times we unlocked it manually. Still, I was hung up on the lock to app signal being the cause of our issues and got a august connect adaptor to try and help (plus I read that could help slow the battery drain). Turns out even the 4th gen lock doesn’t allow an external connect device so that was a dead end. Maybe the connect I got is an older model or something but I couldn’t get them to link, it just complained there were no compatible devices at setup). Another clue that this wasn’t the cause should have been that even when using the phone’s Bluetooth signal it wouldn’t update the lock status after the first app unlock. Also when we would unlock from the app the light would start turning green on the lock then end with a red once it unlocked.

Finally found a FAQ doc that said to make sure the notches on the lock adapter were at the vertical position (12/3/6/9 o’clock) when the lock was at it’s ‘default’ position (unlocked). When I swapped out the adaptor to the blue one from the light brown and recalibrated the lock one more time it started working perfectly. No more weird mismatch between the app and lock position even when the WiFi signal was good! Range of motion is much farther when the lock opens now and it has a fancy chirp to show it unlocked correctly. That chirp made me so happy after fighting with the app this long, but it didn’t compare to clicking the app a second time and having it reliably relock immediately.

It felt like it was ‘almost’ working before figuring this issue out so I assumed the app/some buggy firmware was at fault but it was installation error on my part! The rest of the install was so easy. Oh well.

Also, go get the rechargeable 123a batteries for this lock. Saw that tip from someone else and just got two sets to swap between. The disposable batteries drain pretty fast and are expensive.

Reviewed in Canada on November 30, 2023
I bought this lock as part of the smartization project for my home (e.g. smart plug, smart thermostat, etc.), and it works perfectly with my home's WiFi network, where I don't have to look for keys everytime I'm going out or returning home. Easy installation with clear instruction, and user friendly App is also a great add to my 5-star rating 👍
