When I started at Ars in the summer of 2022, the next generation of smart home standards was on the way. Matter, an interoperable device setup and management system, and Thread, a radio network that would provide secure, far-reaching connectivity optimized for tiny batteries. Together, they would offer a home that, while well-connected, could also work entirely inside a home network and switch between controlling ecosystems with ease. I knew this tech wouldn't show up immediately, but I thought it was a good time to start looking to the future, to leave behind the old standards and coalesce into something new.

Instead, Matter and Thread are a big mess, and I am now writing to tell you that I was wrong, or at least ignorant, to have ignored the good things that already existed: Zigbee and Z-Wave. I've put in my time with Wi-Fi, Bluetooth, and various brittle combinations of the two. They're useful for data-rich devices and for things that can stay plugged in. Zigbee and Z-Wave have been around, but they always seemed fidgety, obscure, and vaguely European at a glance. But here, in the year 2024, I am now an admirer of both, and I think they still have a place in our homes.

What does "vaguely European" even mean?

[–] [email protected] 26 points 8 months ago (2 children)

That's how I'd describe Tommy Wiseau or John Waters lol

[–] [email protected] 8 points 8 months ago

Gillian Anderson in her later career also.

[–] [email protected] 3 points 8 months ago

I would have never thought about it, but somehow you're exactly right.

[–] [email protected] 11 points 8 months ago* (last edited 8 months ago)

Haha, I have no idea. Possibly less corporate, more "small, simple, open system that others can contribute to".
I can only speak in vagueness on the "european-ness", to be honest.
HASS/Zigbee have an open, european feel to me.
HomeSeer has a very american "this is the way we're doing it, it costs this much" feel.

My mind went to IKEA-like with a funny name and modern styling.

But I have no idea if that's what the author meant.

A wall plug came with a Schuko adapter...

[–] [email protected] 4 points 8 months ago (1 children)

I had the same thought. Is it an insult?

[–] [email protected] 7 points 8 months ago

I don't think so.

I think it just means they seemed like standards which were more prevalent in Europe, meaning support might be better for Euro hardware, or that the (presumably) American market was leaning in a different direction.

What i have a problem is the developer accessebility.
I want to build my own sensors into boards and use those, but the devboards are so expensive, its not worth it.
A board with an esp8266 costs just 1-2€, with zigbee its 20-25€.
Might aswell go for the new esp32 versions now and use thread.. and its still cheaper.
(though that wasnt an option a few years back, best option there was esp-mesh which kinda sucked)

[–] [email protected] 13 points 8 months ago (1 children)

esp32-c6 (supports zigbee), is pretty cheap.

[–] [email protected] 16 points 8 months ago (1 children)

If only ESPHome had support for Zigbee on the C6 and H2. So much potential for cool projects.

[–] [email protected] 4 points 8 months ago

I agree, I'd be picking up a bunch of those, if that were the case.

[–] [email protected] 4 points 8 months ago

I've never actually tried doing dev on a zigbee board. A cursory glance puts them at £6.
But I can absolutely understand why ESP is so much more popular. Which is a shame, as I like not having to mess with wifi/BLE.

[–] [email protected] 2 points 8 months ago

Try getting a Zwave devboard 😅

[–] [email protected] 20 points 8 months ago* (last edited 8 months ago) (2 children)

ZigBee and Z-Wave are awesome because they stay functional irrespective of:

  • WiFi
  • Router
  • Internet
  • Cloud

So long as the Home Assistant is alive, everything works. The reliability and uptime approaches the AC mains.

And they allow for battery powered devices to have multi-year battery life.

[–] [email protected] 15 points 8 months ago (2 children)

The internet and cloud points are my favorite. Specifically the fact that those things are out of the picture.

No VLAN configuration necessary. The hub is "the VLAN". They literally can't phone home because they have no route to the internet, with no extra setup necessary. For WiFi devices, I have to make sure they're connecting to the right VLAN and controlled properly, and if I misconfigure something, they are phoning home or joining a botnet.

(This stops being as applicable if you have a sketchy hub you don't trust, but I trust deconz and ZHA fine enough in this context).

[–] [email protected] 5 points 8 months ago

Same here. Not having a path to the internet by default is lovely. Local data stays local without any extra config.

[–] [email protected] 5 points 8 months ago* (last edited 8 months ago)

Exactly. Which allows you to use devices from any vendor without having to worry about the preloaded botnet agent. 🤭

[–] [email protected] 3 points 8 months ago (1 children)

Until Zigbee2MQTT breaks again ;P

[–] [email protected] 4 points 8 months ago (1 children)

Using ZHA for a year and a bit. No breakage so far. Knocks on wood.

[–] [email protected] 2 points 8 months ago (1 children)

ZHA isn't compatible with a lot of recent Hue bulbs. It's a bit frustrating.

[–] [email protected] 1 points 8 months ago (1 children)

Oh really, like what? I have a few E26 models and two strips. I haven't tried any others.

Still hopeful that matter and thread get ironed out. It's the standardization the systems need: no more "download tuya to install"

  • Offline control

  • standardized setup

  • Low energy optimized

Currently I have to run a few different bridges to keep everything happy. Zigbee2mqtt is definitely my most used.

[–] [email protected] 7 points 8 months ago (1 children)

It's funny, I'm eyeing up an air conditioner atm.
And the one I'm focussing on looks pretty special, not because it runs tuya, but because absolute gods in the FOSS community have made a complete alternative firmware for it that works with HASS directly on the tuya host hardware.

[–] [email protected] 3 points 8 months ago (1 children)

Which air conditioner? Sounds like a gem.

[–] [email protected] 1 points 8 months ago (1 children)

This is the github for it.

Honestly, I'm half expecting the version I eventually get not to be compatible!

correct

If a smart home app is required I'm out

[–] [email protected] 1 points 8 months ago (4 children)

I still don't understand what theoretical advantage it has over x10 for things that are plugged in. (In practical terms the HA support for X10 was apparently pretty bad last time I looked)

[–] [email protected] 16 points 8 months ago

I have been doing home automation for almost 30 years. I started with x10, and still have a few x10 devices deployed in my house, so I think I'm in a position to know what I'm talking about here.

There are a few major advantages Zigbee and Zwave have over x10, namely:

  • The Zs are fast. X10 takes a quarter to half a second at best to travel through the house and activate the device. If there is noise on your powerline, it takes longer. Sometimes messages are missed. This is old tech, and there isn't a lot of error correction or signal ack.
  • Phase Bridge. X10 uses your house power line to send signals. You may or may not know this, but (at least in the US) your power is split into one or more electrical phases. The X10 signals are absolutely terrible at crossing from one phase to the other, and it isn't always obvious when you plug something in which phase that outlet is on. This leads to a lot of troubleshooting. Things like phase bridges exist to solve this, but they aren't terribly reliable.
  • Wireless. The Zs don't need to be connected to your powerline to function. There are no powerline x10 devices that run on batteries for obvious reasons. This allows for a lot more versitility.
  • No setting house/device codes. If you have ever actually used X10, you know each device has its own house and device code that needs to be selected (usually with a tiny screwdriver while crawling on the floor in the dark, but I digress). This is all handled digitally and is more or less plug and play with zigbee and zwave.
  • Encryption. Any idiot with an extension cord and some free time can connect to a power jack on the outside of your home and turn whatever they want on and off with X10. There is no authentication whatsoever. Ironic, considering the company most known for X10 devices sold security equipment.

Now there do exist some wireless battery powered x10 devices (the MS16A motion sensor, for example or the DS10A door sensor). These are actually fairly solid devices, and I still use a good number of them in my home. (I have many DS16As that have been in daily use for more than 20 years)

It isn't all bad, and there is no reason to throw it all out if it works for you. However, if you are buying new gear to automate with, there isn't really a compelling reason to go back to X10. the modern solutions are cheaper, faster, more secure, and easier to work with.

[–] [email protected] 8 points 8 months ago

I've never really looked into X10.
A very brief look suggests that the signaling goes over the mains cables? If that's correct, then the big thing for me would be that it separates the communication from mains electricity. Most people don't like messing with 240v, unless they absolutely have to.
Which would mean more needs to be done by an electrician.

[–] [email protected] 6 points 8 months ago (2 children)

I don't know about theory, but the big practical advantage to ZigBee is that it works.

Sorry, that's a shitty thing to say. I'm salty because the only time I tried X10 was 25 years ago, and the experience was less than great. Unreliable switching, spurious commands, slow performance, etc. Sending signals over the power wires sounds great in theory, but in practice there are all sorts of pitfalls, like resistive versus inductive loads, bridging circuits to different legs of two-phase power, or conflicting commands on the wire.

ZigBee has just worked for me, since it avoids all of the potential wiring issues. You just plug a device in, put it in pairing mode, and Home Assistant finds it, interrogates its capabilities, and adds it (by name) with the correct entities. No mucking about with addresses, or adding signal paths to the house wiring. As a mesh network, it's quite robust, since most plugged-in devices act as repeaters.

The downside of ZigBee, of course, is that it may not work well in WiFi-saturated environments, since it uses the same 2.4GHz frequency band.

[–] [email protected] 2 points 8 months ago

Yeah, this is pretty much what I gathered.

As an EE I love the theoretical elegance of using the wires that are already there for communication, but the practical implementation seems to be an issue.

[–] [email protected] 1 points 8 months ago* (last edited 8 months ago)

@RobotToaster @GreatAlbatross oh man, X10 was such junk. Terrible reliability, expensive, clunky. Always awkward as the units plugged into receptacles with little positioning flexibility, and a restrictive ecosystem with inflexible players tying it up in patents for so long. A couple of hundred bucks I blew there was totally wasted …about 20yrs.

[–] [email protected] 1 points 8 months ago

Matter and Thread aren't being forced because they think consumers don't care enough to wait. There are too many people who will just buy "smart" anything, without regard to which proprietary app they need to install.

The market is there. Look at Nanoleaf sales.
