When it comes to buying speakers, one of the most important factors that we consider is the sound quality. However, as technology has evolved, we have also started considering the method with which the audio source should communicate with the speaker, that is, Bluetooth or WiFi. So, the big question is what is the difference between the two speakers?

When it comes to Bluetooth, it is important to understand that the Bluetooth technology is compatible with more devices in comparison to WiFi. This means that with a Bluetooth speaker, you can stream music from your phone as long as it has Bluetooth, whereas, with a WiFi speaker like Sonos, you need to connect the speaker to the internet for it to access music.

In many ways, this makes Bluetooth a preferred option owing to its simplicity and mobility. Connecting a device to a Bluetooth speaker is a simpler task than trying to connect a WiFi speaker to the internet as the latter requires a router. Hence, a Bluetooth speaker is an ideal choice for situations where there is no internet.

However, the sound quality of Bluetooth speakers is inferior when compared to Sonos speakers. Even though protocols such as Bluetooth aptX and Bluetooth 4.0 have been developed to improve audio quality, they work only if the streaming device and the receiver have the same protocols installed. In that case, the best quality one can achieve is slightly better than CD-quality.

On the other hand, with WiFi Sonos speakers, it is possible to stream high-resolution music without incurring a loss in quality. In fact, these speakers have been designed such that they deliver the sound in the highest quality, in all its glory. Furthermore, with Sonos speakers, it is possible to listen to any song, radio station, podcast, audiobook, et cetera, as long as you are connected to the internet. But it is important to remember that setting up the connection may be tricky initially.

When it comes to wireless speakers, the range is another factor to consider. Bluetooth speakers have a very limited range, ranging from 30 – 50 feet. The sound quality deteriorates as the streaming device is taken further from the speaker. However, this isn’t the case with Sonos speakers. As long as the WiFi router is in the center of the house or close to the place where it is needed, the speakers will work superbly. A WiFi bridge can be utilized if need be.

I really wanted Kevo to work for me but it is too problematic. The biggest problem is that you cannot depend upon it to actually lock your door.

When locking, the unit uses “dead reckoning” to decide when it locks. That is, it waits about ~40 seconds after you unlock it, then it locks. What’s wrong with that? Well, the lock doesn’t actually know that your door is closed, it just extends the deadbolt. (August fixed this with their newer gen locks, btw.) Then it reports a status of “Locked” to its app.

But if the person leaving didn’t actually close the door, the door is just sitting there with its deadbolt stuck into the air. The door is *not* locked, as the app status indicates. When the app tells you the door is “Locked” you can’t believe it’s true. And this lock has *no* way of sensing that your door is closed so that it could wait until then before extending the dead bolt. That’s why it uses “dead reckoning”. And as it applies to this lock you understand why the word “dead” is in that phrase. That is incredibly *dumb*. I mean, isn’t this supposed to be a *smart* lock? This makes it a safety risk. You can’t rely on your door actually being locked when the app says so. I’m talking about the 2nd Gen version of this lock. Even the second time around they couldn’t figure out that a door has to be closed before it should try to lock it?? So if you have a kid or someone whom you cannot rely on to be sure to positively close your door, you could be unknowingly left with an unlocked door. But this is supposed to be a “smart” lock. You shouldn’t have to rely on people to do the job correctly, the lock is supposed to be smart and make sure the job gets done, right? A truly smart lock should be able to tell you, “Hey, the door couldn’t be locked.” It shouldn’t mislead you with false positives. FAIL.

What about having an automatic door closer on your door? Glad you asked, because that’s exactly what I have. Automatic door closers can get stuck. With a change in the weather it may not close in the allotted 40 seconds before the dead bolt extends. Or something could block the door from closing completely – a rug could bunch. All kinds of things could happen. What about the touted features of having the convenience of being able to unlock the door from remote or give out eKeys to let the delivery person/dog walker/etc in? They could forget to pull the door completely closed – this lock has no way of knowing that the door is ajar, and it will blithely tell you via the app that the door is “locked”. Now imagine that you get home later that day to find that because your door has been left open, your place has been ransacked or your pet has run away!

Others have written about the incompatibility issues with the phone software. I can confirm this. I’ve had to give out dongles to those whose phones won’t work with the lock. The lock provides logs to show you who has unlocked the lock with an ekey to enter your premises. The problem with the dongles is that the lock does not report when a person uses one – no log entry. You can’t associate a particular dongle with a specific person. So if you need to keep tabs on who is entering a space and need to give someone a dongle, forget about knowing when a person comes into the space. Even with the ekeys, the logs often don’t show an entry for a person unlocking the lock – it’s simply missing.

The other thing is that the number of dongles you can use with a lock is limited to 8. Need more? Forget about it, you can’t, Kevo doesn’t support it. What if someone loses a dongle or you want to selectively disable a dongle. You can’t. You have to reset your lock. But this deletes *all* dongles and ekeys from your lock. You then have to reissue all your ekeys and dongles to your people. Talk about inconvenient.

Speaking of inconvenient, let’s talk scheduling. One of the touted features of smart locks is the ability to give persons selective access to the lock. But the Kevo scheduling is very limited. It can be for any specific day, but not for different times. So if you want to provide the cleaning person access on Monday, between 7-9am, and on Friday between 3-6pm, you can’t. You can only provide selective day access at the exact same time period. EG: Monday 7-9 and Friday 7-9, but 7-9 is all you get. Only the same time schedule for different days. You also can’t provide two different access times for an a given day. Say you want the dog walker to be able to come in Monday betw 7-9am and also 3-6pm. Can’t do it. You can’t do two schedule periods on the same day. You would have to provide access for the total span, 7am-6pm. Dongles can’t be scheduled at all. They are always 24×7.

Oh yea, my unit died early on. It had to be completely swapped out under warranty. This did not inspire confidence. And the batteries died without the lock giving me any forewarning. If I hadn’t had my physical key I would have been locked out. FYI, I also have the Kevo Plus, so my set up is fully tricked out.

I will be replacing this lock.
