The first item is the Aqara cube and sorry I’ve already removed packaging on this one, it was the standard aqara packaging and for those of you who are not familiar with this, it’s basically a smart zigbee switch. It has an accelerometer internally and it can detect you placing it on any of its 6 sides which can then be programmed to trigger certain actions in your home automation. So instead of flipping a switch, you would just flip this cube on your nightstand.

It can also detect other motions like, rotating the cube which can be used to adjust brightness.. Double tapping the cube, shaking the cube, pretty much anything you would do with an accelerometer, they have that built into this cube. So I wanted to give this a try, it does have a bit of added weight to it, which is a good thing, otherwise this would be too light to feel nice. I haven’t yet used it, just took it out of packaging but I’m gonna give it a try to see if I like controlling stuff with the cube from my nightstand. I will not be using this through the aqara ecosystem but rather integrated directly with zigbee2mqtt.

My next item is even more interesting, I’ve always wanted to take a look at one of these fingerprint locks and let me mention this right from the start, these are locks for honest people, so I don’t expect any serious level of security from this, I just plan to install this on a furniture cabinet/drawer something like that. At this level and size any amount of serious force would override the lock and bust it open but it will help me keep some things private in my home or office and it has the nice advantage that I don’t have to carry an additional key. So the fingerprint scanner unit would go into a standard 20mm hole on the door panel, the lock unit would go on the inside.

It uses 4 AAA batteries, I’m not sure how much battery life we can get out of this but they have a really cool feature, a micro usb port on the front of the fingerprint reader so if the batteries which are on the inside of the drawer run out, you can externally inject power and open the lock.Would have been nice for this port to be Type-C but since I will likely never use it.. I guess this works too. And I must say, I was expecting worse build quality, but it feels pretty decent and it responds pretty fast to fingerprint reads, I quite like what I got for my money. ... https://www.youtube.com/watch?v=A1YmpzMBASc
