    This was a OUTSTANDING video! I am an engineer who put X-10 in over 20 years ago and recently moved so it is time to learn the new technology options. Rob explained it all so that you can understand the tradeoffs. And they ARE trade-offs, if there was one "best" we would all just use it. Duh! Excellent discussion on RF, well done! And as a cyber security guy, you gave me a lot to consider. I still have a LOT to learn, but this 15 minute video saved me gobs of research time. In fact, I was keen on the Z-Wave when you started talking as 933 MHz appealed to me as it is not in a congested frequency range PLUS the penetration of 933 Hz vs 2.4 GHz. That was until you taught me about the Connected Home Over IP standards and how Z-Wave "couldn't play in reindeer games." BUZZ! Thanks for playing. Next! Great video! Good starting point for any geek who wants to learn more! THANK YOU!

      Connected home over IP makes sense if you have a strong WiFi network. Z-Wave makes sense if WiFI coverage is spotty in your house. Then you can take advantage of the Mesh network of Zwave. I was thinking about the Lutron line, but that is proprietary. The switches are extremely reliable. One person has had Lutron switches in his house for 5 years and never replaced one.

    A good overview. However you missed the Z-Wave is extensible language. What this means is manufacturers have to use the existing commands if one already exists but can create new ones if they do not exist in the spec. So for example if someone wanted to make a Z-Wave instant pot they would have to use the Z-Wave standards for on and off but they would get to use their own commands for setting the temperature. Z-Wave is actually administered by the Z-Wave Alliance which while mostly controlled by sigma designs does have several dozen companies involved who wind up voting on which new commands to add to the protocol.

    All Zwave must work with all other Zwave by its manufacture specs. Zigbee is "open source" but does NOT have to work with other Zigbee devices. This means that Zigbee can work one day then not work because of a software change. Just be aware of this when you design your systems. Best advice is to get a hub that has all of the "radios" you will need.

    I have to admit that my default reaction to home automation videos on CZcams is pretty much me rolling my eyes at the IT geek who has decided he can teach the world about HA, BUT this is actually pretty solid. It’s hard to find fault in a factual review of the technologies. Good stuff man!! 👍 My much more subjective opinion can be summarized as follows: build your HA primarily on a non-cloud controller (just trust me), ignore WiFi devices as an option COMPLETELY (unless you come across specific use cases like Shelly relays), use zigbee for anything battery powered and Z-Wave for anything hardwired. Lastly, run run run run RUN from the SmartThings hub (the hub, not the zigbee devices), it is absolute trash. The only hubs I would consider at this time is anything running HomeSeer, and the Hubitat hubs (the latter really has really impressed me, even though I have been using HomeSeer for over a decade). Just my $0.02

And they have very wide support for devices and you can even make new devices supported yourself. Only minus is that you need additional powered CC2530 sticks to get over 15 zigbee devices.

    @10p6 Před 2 lety +3

    Interesting video. Now my 2 cents :-) Bluetooth avoid. Wi-Fi avoid as it congests your Wi-Fi router (if you have a lot of devices) and a bunch more issues. Zigbee ignore as it is flaky, and everything seems to interfere with the devices. As for Z-wave and Smartthings, I have 79 devices devices on Smarthings, the vast majority of them being Z-Wave, only RGB lights and water leak sensors are Zigbee (RGB lights are actually hue , but even they will connect directly to Smarthings without the Hue bridge.) Out of those 79 devices, only 1 device runs on the cloud, everything else runs locally, even most routines / automations. The only thing I do not like with Z-wave and Zigbee is a lot of devices use stupidly expensive batteries, hence why I hacked some of my devices which use 2450 batteries, to use 2 x AA batteries which now last massively times longer. As for that 'Group' , i'm pretty sure most of that will be cloud processed and all your information then being shared by everyone.

      This was going to be my comment as well. I have been using HomeSeer for the last 12 years and would estimate I am 80% z-wave. Home automation has nothing to do with being able to turn your lights on and off from your phone (that is remote control, not HA). Home automation is all about whatever system you select being able to remove manual steps and automating the results. IMHO the event engine and extendability (plug-ins) of HomeSeer makes it by far the best option currently and should be mentioned in every HA video. ... but you know, just my opinion 🤗

    FYI, Silicon Labs fully aquired Z-Wave in april of 2018 so it is no longer true that is licensed by Sigma Designs. Silicon Labs has since then changes the licence to make it a more open standard so that other companies can license the rights to make Z-Wave chips, but as far as I know no other company has done so as if yet.

    Great explanation! Learned a few new things (I had no idea of C.H.I.P. for example) and also re-affirmed some stuff that I already knew about. There is however one extra popular solution that you missed out on and which is primarily used by big companies: cable, and in the case of home automation, ethernet cabling. It is by far the most reliable option and also the one that has the lowest latency (speed is not as important, when your temperature sensor requires 1Gbit/s speeds you might have other problems) and you can send out electricity as well which eliminates the need for batteries. That being said, installing cable everywhere isn't something to get started in the IoT stuff: wifi and zigbee work just as well. Can't speak for Z-Wave as I don't have any device that uses it.

      Just checked and it seems like Sigma Designs went bankrupt. Wow.

      They aren’t bankrupt, they were purchased by SiLabs, one of the largest chip producers in the world.

    Very informative video presented professionally. Though versions 2 & 3 SmartThings hubs are compatible with just about everything, past experience with a cloud-based doorbell cam's latency (person was usually gone by the time I got the notice, so I couldn't communicate, but I did get the video) has made me investigate beyond cloud-based systems. Have you reviewed (or found one on) the Zooz Z-Wave S2 USB vs. the Aotec Gen5 Plus sticks? If the capabilities are similar, do you know whether the compatible software suites are comparable in features?

    think it's important to clarify something, about this "No such thing as incompatible wifi" point. Because for the context of our topic, it's important to understand that these _Wifi_ "smart devices" are not directly operating by receiving and reading, writing and sending, raw instructions and status information - that just happen to be wrapped up in the type of packaging neccessary for sending and receiving them through your wifi router (etc). They basically have tiny, simplified computers inside, running their own software. And the data being communicated back and forth, is in a language and format this software understands. It is then this software that decides what to with it, and eventually instruct the hardware inside to do something (like send power to the LEDs inside its lightbulb). However, this software and the languages it knows can be different even between different types of devices from the same manufacturer, and especially so for devices from different brands/manufacturers. Also, each device has its own ID. So even if the case where software running on two devices from two different brands, happen to speak the same language - they may look at the device's ID, see that it's not a device from the same brand/manufacturer, and then just ignore or throw out any communication going to or coming from that device. Or, in some cases, one of them may have a very rudimentary understanding of one language both knows, and therefore only send, receive and execute very basic instructions. Like only turning on or off an RGB lightbulb, not doing any adjustment of the color or dimming.
    As a metaphor: These devices _do _*_not_* operate like if you make an image of a lightbulb and a lit up power button, prints and puts that image in an envelope and the right type of stamp (here your postal service have strict regulation of which envelope types are allowed). Then you sends that envelope through the postal service (your wifi router/network) to your friend, he/she opens the envelope, see the image (image illustration is used to sidestep any language barrier) - and then know to push the button to switch on the lightbulb, and does it.
    Instead, these devices are running software systems, like a very small and simple computer. And all incoming and outgoing communication goes through that software layer. Like if you and your friend is working for two different companies. To communicate, you call up the company Communication Department and tell them what you want your friend to know. Then that department create the letter, put it in the appropriate type of envelope, and send it through the post - to be received by your friend's company's Communication Department.
    The important thing to note and understand here - is that this software layer, the Communication Departments - they don't just universally perform this task. They also decide which companies they are willing to send mail to, and receive mail from. And it's very common that they will only process mail to/from from other branches of the same company.

    Great info!. Not really related but why do electromagnetic charts nowadays start showing the lower band widths on the right, and when did they change over?
