Another amazingly well articulated video. I really appreciate how you make difficult technical concepts understandable for less technical folks. Keep it up mate!

Great video, have always wondered about a single point of failure in larger applications. Thanks again!

Thanks for the informative video!

Another brilliant video - Again, thank you for taking the confusion out of a platform that can at times seem like a daunting task to understand

Nicely done. Learned something new. I knew about the hub but didn’t know about the routers that help extend coverage. That will solve some issues I’m having. Thanks!

Really appreciate this series! I know OF ZigBee/Z-Wave but haven't worked with them much. These are doing a great job of explaining the processes for choosing products for my smart home.

I’m loving this whole “back to basics” series

Really helpful and clear video. Thank you so much!

This was a great video! I love this series. Please keep to great videos coming.

I really like that you explained at the beginning that ZigBee is almost synonimous with smart home, because I was most interested in most popular ZigBee use cases

Very helpfull! Thanks!

Great video!! I literally just started messing with zigbee devices this past fall. I had used zwave in the past. Fully aware of that single point of failure at the coordinator (im working on that in my k8s cluster lol) but I absolutely love zigbee for all the pro's you mentioned. I passed this video along to some buddies of mine that haven't used zigbee because i think this is a very clean straight forward explanation. Great job!!

Love your videos thanks

Great video. Thanks for sharing

Great overview of Zb. Appreciated.

Great content

Another nice thing with Zigbee is the possibility to bind devices so they can talk directly to each other.

Great video and much appreciated. When is the Sonoff Zigbee bridge used? Is it a router? Does it take the place of a coordinator? Thanks!

I recently installed a Conbee2 coordinator in my office which is in the front of my house. My garage is 50-75 feet behind the house and I was pleasantly surprised that I zigbee devices in the garage can connect. I do have an outdoor zigbee outlet on the garage to act as a router.

thank you! you made ZigBee easier to understand than my university book did.

Thanks for this video ! I will start with Zigbee, so I wonder if I have to buy the ConBee II or the Sonoff Zigbee 3.0. Can you give me advice ?

Nice video. Question: can routers increase the number of devices you can use?

Besides the funny way you pronounce router, I look forward to your videos. 😀. I already have researched a lot of this information but listening to someone else summarize it helps cement my opinions.

Love this! I am looking for a smart home hub and app. Your video suggest Zigbee will do this. What app do you recommend?

I like Zigbee more than Z-Wave, seems like everything I set up works better, and the cost as well has been better overall.

great video. im a massive fan of zigbee myself despite issues in the beginning with poorly designed devices that drained a 2032 cell battery in weeks then ceased to funtion completely. not great when you bought 9 lol. with the esception of those particular devices ive had very few issues with the sonoff range and i have the lidl zigbee bulbs both rgb and non rgb in almost every room in the house. my biggest issue with zigbee is it seems there is a lack of availibilty in the uk and i have to get most devices from china or end up paying double

Could you let us know whether you use Zigbee2MQTT or ZHA with HA? Which one you recommend and why? Cheers

Forgot the link to the series playlist in the description... Thanks for the info

Thank you for doing this series it great to have information to go back and reference. Do you mind sharing the name of the program you had on the video that showed different devices and their details. That looks very helpful for those of us who are using a “few” devices in our design. Thank you

Could you please explain what is the difference of mesh WiFi than having multiple wired Access Points with the same security, modulation and SSID names? Also is it possible to do a mesh WiFi with Access Points from diffetent vendors? Is mesh WiFi using a single frequency throughout the whole wireless network?

Hi, is there anyway that I could turn off Ewelink app notifications automatically when I reached home and turn on again when I'm leaving home. It would be very helpful since I used the Sonoff motion sensors as part of my home security in conjunction with Google assistant and android phone. Thanks .

Many thanks for the great video. I started off with wifi as it seemed much cheaper to get started and Tuya was the platform of choice. I also found that WiFi was the most common protocol for makers particularly if one used the ESPnn range of microprocessors - it seems a lot easier to build firmware for. The challenge I hit was that by the time all the lights and some sensors were on there, I was rapidly approaching the 255 limit on IP addresses! It was then that I introduced a Zigbee network as well, particularly for the small sensors that were battery powered. I have a couple of questions (I should state that I 'm still an over enthusiastic HA novice!) 1. Can WiFi handle more than 255 devices (Using LocalTuya and OTA one tends to have to reserved IP addresses)? My reading suggests that is depends on your external IP address but it was all too confusing! 2. I have heard that there can be interference between Wifi and Zigbee due to common frequency band. Any thoughts on that? Once again, thanks for the great video/s.

Nice video, but I thought this would be a video about the protocol. Packets, headers, ack-nack, buffer windows, duplex , etc.

One thing I’ve been trying to find a good answer to, is just how ‘smart’ is a zigbee router? Does it interpret packets before sending them on? Or does it just blindly direct them to the coordinator? I use a cc2230 stick for my coordinator, but I’d like some prettier looking routers in the network and debating buying some of the ikea smart plugs or similar, but can’t find a definitive answer if they will happily route packets from devices they don’t understand.

Great presentation! I really liked the concept of the dual comms of the Insteon (powerline and wireless). Just too bad the company sucks so badly that it never did take hold.

Have you come across any dual Zigbee in-wall outlets?

which zigbee hub is the best for home assistant

Hi, are you using Philips hue bridge for your lights ? Or a do you use zigbee2mqtt/ZHA for that? I have so many hue lights that i need 2 hubs (philips hue), so I was thinking to build a need zigbee network using zigbee2mqtt. Or is it best to use hue bridge for the lights ?

Great info as always 👍. I am moving away from the Zigbee/Zwave thinking I originally had since I'll probably gonna setup a decent UniFi network both indoors and outside in the yard so full WiFi coverage shouldn't be a problem. Is BLE gonna be featured in this series as well? I'm thinking of using BLE temp and humidity sensors in the henhouse, bunny houses etc. It would be great (I think) to have small weatherproof "blobs" and a hub/controller (or what it's called in the BLE world) that connects to HA. Keep it up, I'm learning heaps👍

Can a Zigbee hub also understand my wifi doorbell? Currently when someone rings the bell my wifi light in the hallway goes automatically on for 2 minutes. But if I replace the light with a zigbee switch can the doorbell stil do this?

I use wifi, zigbee, and z-wave, so a nice mix of it all, and of course all together with Home-assistant

How does the devices respond quickly when they are in sleep mode?

What kind of pc desk is that?

I'm using zigbee, Aqara M2 to be exact, mostly because i really like Aqara devices, but their implementation is far from perfect, i really hope future standards are more rigid and don't allow manufacturers to temper with them, thus sustaining a more compatibility network for smart devices. One question that i do have is, you said zigbee works on 2.4ghz but its far from 2.4ghz wifi, my question goes into if 2.4ghz zigbee devices, routers create noise or affect the performance of the wireless network?

On HA, can we use zha and zigbee2mqtt with the same hardware? (at same time) Tks

Surprised no one has commented this already... Ooooh the ZigBee! 😆

Has oido de la frase: "Keep it simple" ?¿ Con proxmox u otras infrastructuras de virtualization haces todo lo contrario. Y aquí me refiero a Domotica y Home Assistant en particular. Si quieres evitar problemas, dedicar una maquina entera a tu sistema de Domotica es lo mejor. Para que añadir una capa sobre otra capa sobe otra capa¿?

my zigbee motion detectors with Tuya seem to have decent signal strength at 5 meters line of sight. But put a gypsum wall in between and the signal strength drops to bad. Manufacturer of zigbee gateway says 0 - 5 meters. This is ridiculous.

Interesting! But if a ZigBee radio is mostly off, how does a ZigBee switch respond so quickly to being remote toggled? Or do ZigBee switches not sleep like sensors do?

I’m excited for the 56k modem explained video 😂😂

Do two nearby ZigBee coordinators cause interference in the network? I mean, if two different ZigBee coordinators are installed nearby but integrated into two different homeassistant servers, will their signals interfere with each other? I have noticed a weird behaviour once, hence asking

i own 3 sonoff zigbee door sensors and they've mostly been a nightmare so far. the worst part is trying to reconnect with my smarthings hub when they get offline. That's not fun. But yeah, when they work, they work well..

3:37 correction: On low powered WiFi devices, such as the ESP8266 and ESP32, you can turn off the radio and make the device go into deep sleep, all while having an external interrupt wake it up. While I know how to make custom Zigbee devices, I use WiFi in my mailbox using an ESP8266 in deep sleep, and the power consumption is ridiculously low. Easily comparable to Zigbee (I know, because I tested the power draw very precisely).

Z wave please!

buddy you look like superman

I see so many different brands of zigbee Gateway / hub. Moes, Tuya, LoraTap etc... 1. It states it does wifi. Does this mean that it communicates to my wifi router and the hub/gateway not connected to ethernet correct? The zigbee hub/gateway does not communicate directly with wifi outlets? 2. Wireless or wire (ethernet) Benefits - I read one article that states if wired Zigbee could handle 300 zigbee devices vs 50-128 on wireless. 3. So many models are available for sale.... How do you tell which one is the latest model. I've read the spec on one site that states its the latest model but when I read the specs it has the same exact thing as the old model. 4. Stand alone? Is zigbee stand alone. Do I need the internet for this thing to work? So if i had a lan network no internet will I be able to see my devices and get updates. I use Home Assistant. NO one wants to live without internet but there has been time where internet is not available. It would be nice to know that I could get updates from my home assistant. Thank you reading my questions and posting the video.

Ik kocht een zigbee schakelaar enkelpolig waarbij geen neutrale draad nodig is. Het enige dat werkt is het manueel aan en uitzetten van het aangekoppelde lichtpunt. Via WIFI geen mogelijkheid tot contact maken. Het blijkt bagger te zijn vooral als men dan doodleuk zegt dat er nog een hub nodig is.

Not entirely correct on the network specifics of WiFi. Obviously it's allowed for WiFi devices to turn off their radio completely. The magic WiFi uses is called DTIM. You can usually set the interval of those messages in your advanced settings. In short it allows a device to notify the access point that it will sleep and wake only up at DTIM interval multiplied by the beacon interval. For example DTIM interval is 5 and beacon interval is 100ms would mean that the client would only wake up twice per second and can deep sleep its radio and won't miss any packages. The WiFi AP will buffer all communication in the meantime and set a bit for the WiFi device to notify it of communication for it so the client can ask for the buffered data and receive it. Main issue here in terms of power saving is usually broadcast messages or multicast while the AP doesn't support IGMP snooping. The latter means that multicast will be broadcast as well. This usually leads to several packages to be delivered to all wifi devices each second (mostly absolutely stupid stuff nobody cares about but Windows decides to send out anyway). So that's the real reason you have power consumption issues with WiFi.

Tuya told me low power devices offline status are not updated real time by Tuya app. Yeah.. no kidding, it takes about 24 hours . Yeah that is really helpful..if you live in the future..

@3:40 why do you say wifi device cannot go to sleep? All my battery operated ESP32 devices sleep, wake up, measure, send, go to sleep.

Sounds like a much worse system then EnOcean. I guess different up and downsides.

Unlike your WiFi video, this one seems to be very incomplete, especially when it comes to cons of Zigbee. No mentioning that Zigbee will often conflict with your WiFi since they are both using the same frequency with very very limited number of available channels. That while Zigbee claims to provide mesh capabilities, it's not a true mesh, as the end device will always try to connect to coordinator, even if the signal is really poor, and will only connect to a single router if it can't directly reach coordinator. Nothing about lack of any type of self-healing or even forced healing of the network. And that depending on the configuration of your house, the more Zigbee devices you add to the network, the more saturated the spectrum becomes and the less reliable your network becomes.

Are all Zigbee Devices Routers, or is it just Specific Devices ?

Super great videos!! Finally figured out what is Zigbee...different smart home protocols confuse me a lot🥲
