I was skeptical at first after reading some of the bad reviews however the installation was easier than I thought. I didn’t have to make any extra holes in my door, which was great because my door is not made of wood. It’s worked so far with zero issues. If it makes it past the return date I will come back and update my review.Easy to install and use. Great for when you are out of the country and need to unlock your door for familyBought it to communicate with alexa so I can unlock & lock my door from anywhere. So far it works. No problems.I was not able to register the gateway. Asked for support multiple times on different ways with no success. Finally I was contacted by Marina who resolved my issue quickly. That was great!I got the Smart Deadbolt from SMONET and wanted to make sure it was tied to the Wifi. I bought this gateway and it was easy to set up and works great. The dead bolt finger scanner works and I get alerts by the gateway on who unlocks the door. I have had this for several months with no issues.If you get a smart lock from SMONET, get this gateway, you will not be disappointed.I liked talking but it would nice if you had instructions that were easy to follow. The the product was easy to install once I got good information on the phone.I love everything!!!!Updated: Their customer service is impressive and reached out to me about the issue I was having with the gateway. They gave me two options to try out to see if the gateway would work better. The distance between my lock and gateway is OK but I was also told to look into my wifi network. Though I haven't had a chance to try and test this, it wouldn't be a problem with the gateway.I had no problem installing the gateway nor getting it working with the lock and my Google Home. However, when I tried to unlock the door remotely it didn't work. I always get an error on my phone mentioning the Bluetooth. Usually takes a couple of tries to get it working.TTLOCK skills not available in Canada avoid this product if you are CanadianBought this lock and gateway to use with my echo dot only to find that the TTlock alexa skill isnt available in canada. Extremely disappointed that this was not mentioned before i purchased it.I have been reading the review before to buy and wasn't sure if is worth wasting time behind this. Well I bought and can assure it works(at least fir now) and see the attached screenshots if you are having any trouble with unlocking remotely. Just go on SETTINGS AND ENABLE REMOTELY UNLOCK. It should work.And yeah don't expect much from the seller's customer service.WORKS IN CANADAFirst off it barely works. Mine is less then 10' from my lock with clear line of sight and the signal is labeled as weak. I can not get it any closer without have wires hanging, if you have more then one lock are you required to have 1 gateway per? Unless the locks are 4 feet apart this would never handle more then one lock.Secondly, and probably the biggest deal breaker is what does work is seriously limited. You can remotely lock it, but not remotely unlock it. You can't make any setting changes or operating changes without being within bluetooth range. This is supposed to allow remote operation of your lock and it doesn't work. You can create a user and password then give that code to who you want through... why can't I just open the lock for them from my phone? I don't want to create an account every time someone needs in.I'm sure this can be fixed through programming of the app, so I really hope it does. Until them I am returning the gateway as it is a waste of 60$I bought this so I can monitor the locks and make the areas more accessible for staff and hoping to preventing the juggle at the door with hands full to both areas of access at my work. No such luck. this device needs to be within 2meters of the lock and from what I am able to come to the conclusion of requires 1 per lock. I haven't been able to get the device to access both locks I own :(
