Great value for a matter and thread enabled lock
One of the first matter with thread networking locks. Matter will let you use Apple, Alexa, etc all at the same time if you want. Thread will double battery life if using Apple home. Eufy resolved no response issues with a firmware update. Got low battery warning after first week so I unpaired Alexa to minimize use of WiFi which eats batteries. Batteries seem to be lasting much longer now. The E30 looks good, is reliable and future proofed with matter and thread. Glad I worked thru initial issuesUpdate: looks like the low battery warning was false. Batteries still had 1.5 volts. Eufy fixed with firmware update. Same batteries read 100 now.Update: had it for 8 weeks, batteries at 89%. Operation is flawless. Make sure you update firmware, have a thread border router if using Apple Home, a good WiFi signal as a weak signal will eat batteries. This is still one of only 3 locks that have native matter over thread. I.e. no hub

Works great, easy to install.
I purchased two of these to install into a home we just bought. The old deadbolts were keyed on both sides and flagged as a hazard in case of fire, there was no way to unlock them by hand unless you had a key. The eufy Smart Lock seemed like a good way to fix this. The first door lock was installed in about 20 minutes… worked perfectly. The second door presented more of a problem – not because of the new lock – but because the old deadbolt had an alignment problem that created issues with the eufy Smart Lock. It was eventually solved, and is now working properly. I highly recommend these… they’re very reasonable in cost (in fact I plan to buy one more), and work great!

Much Better than The Rest
I’ve gone through a myriad of smart locks. As a latchkey kid growing up, I lost a LOT of house keys. I’d have to regularly call my Gran to come let me into the house after school for lack of a key. As an adult my luck didn’t change. Which is why I absolutely adopted smart locks the moment they came out.I’ve tried them all. The big names like Schlage are expensive. The No name versions are either unreliable (Think standing in a torrential downpour for 10 mins while your lock says your fingerprints aren’t recognized and they backup keypad also didn’t work well while wet). Then there were some who would eat through (4) AA batteries a week.I was about to give up and go back to a life of losing keys repeatedly when I found this Eufy lock on prime day and decided to give it a shot. Best decision I made. Not only does it look great, it works EVERY time. The more I use it, the faster it learns my fingerprints and the faster it opens. Plus I can use my Apple Watch to unlock it from my car if it’s raining and I’m in a hurry. It has a lot of the same features as the other brands, but the Eufy lock actually works reliably. I’d highly recommend it and will be getting (3) more next prime day so I have them on the rest of my external doors leading into the house. Plus it really pairs with the other Eufy products in their ecosystem.

Updated Review: I originally had a ton of issues with this lock not responding in HomeKit but after a few updates (now at 1.0.8.7), the issues seem to have been resolved. Haven’t had any issues with it not responding in Apple Home anymore so it seems like it’s safe to buy this now.Original Review: If you’re looking at this lock, you’re probably paying a premium for matter, thread, and HomeKit support. Unfortunately, all of these things are completely unreliable.Like other reviews, it works for about a day or so in HomeKit then it just randomly gets stuck with “no response” and the only thing you can do is remove it and set it up again. It seems to constantly drop from the Thread network because I have an Eve smart plug literally in the same room and when I check the network, the Eufy lock is gone yet I never have any issues with the Eve plug in the same room also using Thread.Works fine over wifi but if that’s all you need there’s no point buying this more expensive model.

There is not a matter code. Don’t even see the “Works with matter” option. Waiting for response from tech support. Will probably need to return.Update: the Eufy (Anker) technical support confirmed that this smart lock does not support Matter. False advertisement? If you need Matter, you may need to consider something else.

I bought 2 eufy smart locks e30 it works good but one is missing 2 spring in the box battery and I return it that why only 3 starts
