eufy E31 Keyless Entry Smart Lock with Fingerprint Reader

In short, this is a great product, exceptionally easy to install and functions well enough that we decided to purchase a second. After choosing to go with Eufy's camera products for our new home, we opted to add this smart lock to our back door given that it's the one we use the most. We were also intrigued/hopeful about the fingerprint reader - with a toddler, fumbling with keys trying to get in, especially if carrying groceries, is a tedious process, and we wanted this to make life easier. Ultimately, it has done just that while providing peace of mind at all hours. The installation process is remarkably simple and the app walks you through it step by step. We found the provided strikeplate to not fit on our doorframe correctly so we left the existing plate, which caused no issues. I would absolutely recommend using the Eufy app rather than relying on Home alone (or any other Matter-connected system). The app provides far more options to customize to your needs/wants, including adding numerous entry codes and fingerprints, as well as guest-specific codes. Adding fingerprints is quite simple and closely resembles the process from older iPhone fingerprint scanning. However, keep in mind how you expect to actually scan your finger when (un)locking. The scanner works well and does learn better over time, but it is still a bit sensitive so if I try to put my thumb over it sideways or upside down, it often rejects the read because I scanned it upward originally. An easy workaround is simply adding additional prints for those respective fingers from different angles. However, it's more important for security purposes to use the app simultaneously with Home/Matter because the app is more reliable and consistent. I have never had the device disconnect from Home or not be reachable/usable, but I don't always get notifications when the door (un)locks from Home. The Eufy app is more reliable in this way, not only pushing alerts immediately but also notifying who is doing it when it happens from outside (by fingerprint) or how it failed. I believe some of their newer premium locks perform better with Matter in this way, but ultimately it's not a deterrent for me given that Home still consistently shows the status and allows me to (un)lock the door directly, and I use the app already for the other Eufy products. In all, although not always flawless in execution, the lock works really well. The battery is long lasting still showing full bars of charge after two full months of use, and the fingerprint reader is a nice addition that works on first try the majority of the time but the personalized codes are a phenomenal backup with a key as a tertiary option. We purchased a second lock recently for our other door simply to add the peace of mind knowing when the doors are locked, as well as being able to autolock at night. I'd highly recommend, ESPECIALLY if you're already bought into the Eufy system.
