I’m writing this review because Ultraloq said they would send me a free bridge if I wrote a review. Manufacturers should be careful about what they ask for.I bought the Ultraloq because it was the only Wifi lock that I could find that was not a deadbolt lock. For this application I wanted a door-knob keypad lock that could be controlled remotely.The ratings and reviews were quite good.The lock is very attractive and mechanically well made. Programming strictly from the keyboard is a little awkward but that is just until the device is paired with a bluetooth device.Three problems show up at this point:1) The lock is a bluetooth lock, not a Wifi lock. Ultraloq sells, for an additional $40 or so a Bluetooth Wifi bridge. So it is a little kludgy to begin with. (By writing this review they’ll send me a second, which I may sell on ebay.)2) The second problem was that I had continuous problems with the bluetooth, before I installed the bridge. To save power the bluetooth shuts off after 25 seconds, if there is no use. This meant that in the middle of a multipart operation, the bluetooth would disconnect and not want to reconnect quickly. It would often take while to get an initial bluetooth connection. I think this is because the lock takes a moment to enter bluetooth mode after being woken by the device running the application. By then the app has decided there was a timeout and things get out of sync.3) With the bridge, even though we have five bars on our Wifi everywhere in the house on other devices, including next to the Ultraloq, the bridge would read poor Wifi Signal strength. Unlike most Bluetooth devices, which have a range of 10 meters, the lock has a range of 3 meters, meaning that placing the bridge where we received good Wifi and good Bluetooth was impossible. The bridge is now placed six feet from the lock but reports that it has poor bluetooth and poor Wifi connections. Remote communications with the device can take five to seven minutes to establish and time outs are frequent. However, I have always been able to remotely program new users, though the process can take twenty minutes. (I am on the west coast, the lock is on the east coast.)We have given up on the fingerprint recognition. We thought it would be great time saver (though having fingerprint recognition did not enter into the buy decision). Instead, it rarely works and no lock user attempts to use the fingerprint facility any more.I have not tried the temporary users, which require the user to use the app, rather than a physical passcode. That you CAN NOT have a temporary user who uses a passcode was a great surprise and a disappointment. To be honest I felt like I was the victim of a bait and switch. Because I had such general bluetooth problems, I just add a permanent user and then remove the user when they no longer need access. Debugging bluetooth connection problems from across the country where it can take me five or more minutes to connect to the lock is much more than I want to take on.Battery is starting to be a concern. The device was installed nine days ago. Battery strength has gone from strong to medium. I am on the other side of the country, installing new batteries can be an issue.It is possible that it is just this one unit. There wasn’t time to have new unit sent out before I had to leave, so I did not bother with support. I was sent a survey where I reported some of these issues, but no one followed up.There you have it, a good-looking product, with great potential and the only one I could find that was not a deadlock.Epilog: It is two am East coast time. I just accessed the lock to grab screenshots and it worked flawlessly. Could the problems be server problems at the hosting site? (Keep in mind, that where a Zwire lock can run on a local server, Ultraloq, like Nest, requires the manufacturers server to operate.) I tried again at 3am, same problems: no response.
