General Discussion

I'm also in the Z-Wave camp, with about 100 devices in my mesh. I still have some on Vera, so I actually have two Z-Wave networks active in my home. There's no question that Vera was a big contributor to problems with early Z-Wave experience. Even my oldest devices run well under Z-WaveJS. Multi-sensors that needed battery changes monthly on the Vera run for months without a change on Z-WaveJS (I suspect Vera's frequent restarts and "configuration" of each device each time are to blame). With the rapidly-declining stability of Ezlo's Vera cloud infrastructure, especially Alexa issues of late, I'm planning on being entirely off before March 1. I've definitely had a few Z-Wave devices give up the ghost (or the radio); mostly older devices from lesser manufacturers of the time. The largest single group of switches and dimmers I have are all Leviton and around 11 years old, and I've only had one fail (radio died, otherwise functional). GE/Jasco seems to have held up second best among the high-age devices. Many of the other brands didn't make it two years, and those brands no longer exist, too. Everything I've bought in the last 4-5 years is holding on well. I think Zooz gets the award for most-improved. I didn't think much of them a few years ago (and told them so), but their more recent offerings have been stable and well-supported. Part of the recent stability may be due to a campaign I went on several years ago (bored during Covid), where I found and fixed a number of small electrical problems in my house resulting in a variety of neutral issues (that is, issues with excessive current on the neutral wire). One of the most egregious was that our clothes dryer had been installed by the delivery guys to our four-wire connection with the neutral and ground bonded inside the dryer -- the bonding wire should have been removed for the four-wire service. This resulted in some fairly high circulating neutral and ground currents throughout the house, and in combination with other problems found (loose neutral or ground wires at receptacles, for example) was potentially hazardous and may have led to the failure of those less-robust devices. As I said, the last few years, I don't recall replacing any devices, so I've either eliminated a source of induced failure, culled out all of the weak, or both. I also have whole-house surge protection on my main panels. When my Internet was cable-carried (it no longer is), I had surge/lighting protection at the entrance. I'm not enthusiastic about WiFi as an HA protocol for a few reasons: power demand, crowded bands, and user knowledge/security. While I love the simplicity of the Shelly WiFi-based devices and use them without reservation, they do not compare in battery life to even the oldest of my Z-Wave devices (well, those no longer on the Vera). The powered devices are fine. Powering many WiFi devices also seems to be "unevolved" -- Shelly gives you terminal connections for line voltage when powered; most others are USB micro or C at 5V with a wall wart, which truly sucks, and finding small UL-listed power supplies that can (and must be) safely installed in a US single-gang box or other enclosure is a nuisance and would make an insurance adjuster throw down his clipboard and walk out. WiFi generally is in increasingly crowded bands. In my neighborhood, the list of WiFi networks I see anywhere in my home that are at -60db or higher (i.e. strong) is long. While it used to be that unsophisticated users would simply crowd onto whatever preconfigured channel their router used by default and I could avoid them by changing channels, newer APs and firmware seek out the less-crowded channels automatically and spread out, so now every channel has a dozen competing networks at 2.4Ghz (relatively few I've found can do 5Ghz). Z-Wave's band has actually become less crowded over time (my neighbors finally abandoned their 20-year old cordless phones, I guess). Configuration and security also becomes an issue: rare is the home user that understands that IoT devices should be isolated from the rest of the network. Their eyes glaze over when you talk about VLANs, firewalls, and DMZs. They don't understand IP addressing, and will use the default /24 subnet their router offers and the small dynamic DHCP pool until the day they add that last Shelly device and now the wife's phone can't get an IP address when she comes home, etc. They will run their vendor-supplied AP at 100% with half-a-dozen 4K WiFi camera streams and wonder why their "Internet" is always slow (they don't even understand the difference between their Internet access and their WiFi network). There's a learning curve to building a solid, secure IP network with WiFi that most users have been shielded from forever and (were told) needed to know nothing about, but if you're going to start putting dozens of IP/WiFi devices on your home network, you'd better learn it and know it and do the work it takes to do it right at scale, or it will bite you hard from the inside or worse, the outside, soon and often. I've got some BLE in my network as well, and it works well for its purpose (mostly presence sensing). I remain curious, even intrigued, but... The biggest issue I find, and what I would guess-timate is the biggest barrier to finding a "one protocol to rule them all" today, is that there are no manufacturers that cover the full spectrum of required devices on a single protocol. Nobody makes everything you want, regardless of protocol. So we're left to find the best of breed in each category. I don't see that changing any time soon, or really, ever. The manufacturers follow the money. Smaller manufacturers like Zooz will make a good business out of filling holes that the big guys don't want to address (looking at the ZEN-32 for example). The big manufacturers will always make what they can sell the most, like switches and dimmers. Matter, HomeBridge, and the like... they are effectively controlled by large corporations that are explicitly disinterested in working with small developers. Claiming open source while you maintain a closed, expensive, and opaque certification process doesn't fly for me. Z-Wave, admittedly, shares some of these ills in its proprietary history, but has been evolving to increasingly open over the last five years, with multiple vendors now producing silicon and that competition driving lower cost to implement. Z-Wave is also pretty much a single-interest ecosystem, where Google, Apple, Amazon, Samsung, and others involved in the likes of Matter and HomeBridge have many areas of research and development, and have been shown to quickly and suddenly divest themselves of technology they decide isn't worth continued effort. The players here have been bad actors in the past; I have no reason to believe they will behave differently in future. Like others have said, beware the cloud. Eschew the cloud. It's sometimes a necessary, unavoidable evil, but you'd best minimize it.

TBF I was suprised as well! C

I got a bad impression of Zwave from Vera, quite incorrectly. Should have stuck with it but actually dumped it. Mostly Shelly now, and its Gen 4 modules are Matter capable.

@akbooer indeed so C

Well after much trepidation, and some additional work, I think we are complete. After the successful virtualisation of my Home Assistant and Music Server hosts, and a successful POC of the main Vera / MQTT / MSR / everything else box I did some testing with a spare UZB stick to make sure I could connect it to the virtual host. With a long weekend ahead to solve any issues, this morning I bit the bullet and shut down the hardware device, moved the production UZB stick over to the NAS and spun up the VM. It was not entirely smooth as for some reason Z-way-server was saying it wasn't connected and AltUI claimed an authentication issue, but with some judicious restarts and testing, everything that I can think of to test now works! Some of the Z-wave commands from remote controls are a little slow, oddly, but I suspect the network needs to sort itself out as it's nearly two months 'old' Direct control from web interfaces / voice commands seems fine so I'm not overly worried. So, barring any unforseen failures, I have a fully virtualised system. Better even, when reading about the Synology range, I decided to source an older unit as a backup cluster device so I have some serious resilience Thanks for all the support an input! C

OK here's a useful resource: https://www.reddit.com/r/synology/comments/16tmjoc/the_synology_ram_megathread_ii/ With a linked sheet of all results that people have entered. Despite the thread I originally found, no one has got that particular RAM to work on the sheet. There's another Crucial item: CCT16G4SFD824A Which has 10 reports of working in the 224+ Return initiated, new RAM arriving tomorrow. £10 more expensive so £35. <edit> New RAM in and booted fine. Takes a little longer to come up (I assume it takes a bit longer to check 18G of RAM than 2G I think I'll start another thread about how I'm going to do this. C

Apologies for the delay. Unless you've done some vlanning, those two networks cannot see each other directly so they must be communicating via China. Unless I'm missing something! C

@sammybizz there are quite a few options out there, best to look into what suits your needs best

Have you asked the wife? Mine likes to randomly turn lights on (never off!) just to get me confused Cheers Rene

@Adrian_B "a device" - so you're gonna leave us all hanging?

what kind of things do you need to send the USB port? because that's achievable with any language, and that's possibile with a Powershell script, to start with. but I think Excel VBA is not the right tool for the job and it's not easy to drive something from it.

Not sure if your controller handles WiFi controlled devices?

Hi there. 'Best', of course, is subjective. What are your needs/wants really? Also, what type of IT infrastructure do you have, or are you used to? Apple, PC, Linux, ...? Lots of choice, to be sure.

Just to close this off, new unit installed today and we now have IR back up and running. Even more remarkably despite having to reconfigure my TV activity from scratch in the Harmony app, both Alexa and HASS appear to have managed to remain functional. Logitech were always the bees knees for Universal remote products but at some point they will turn the servers off No apology needed for the Hijack. I'm off to look! C
