There are some in the datahoarder community pushing a PB.
They mostly store Linux ISOs.
z-wave may be easier than expected, as I think the devices stay linked to the hardware dongle used. (This is just from memory, mind!). But if you need to change the dongle, perhaps less fun.
imo, it will be a bit of pain to get everything inside HA, but once it's done, you'll be inside a platform that is pretty open, and commonly used, with lots of other people (hopefully) posting up solutions to problems before you encounter them!
And because it's software that will run on pretty much anything, you have the reassurance that even if something crazy happened, you could just reinstall an old version.
If it were me, I'd clear an entire weekend day, power off the old kit, and work away at getting HA controlling everything.
Because if they remaster it, they can also remaster the price.
Which is probably why they've pulled all the old versions.
Nice to see NC becoming involved with the board.
I don't run that much z-wave due to cost, but I'm all for improvements and tighter integration.
Especially since when I do want to spend money, ZW works very well.
Must be the fracking residue in the water.
Or maybe something like this:

The unit with the buttons on is a simple relay, which hass can control to turn things on and off, and use a heating control with a temperature sensor.
But if you hit the button on the front, it also gives 30 minutes of on, which can be handy if the system had issues.
Or you could have a hass controlled relay, but also leave the old controller wired in on a manual switch.
So if there was a failure, you could go back to the old control by manually flipping it over.
I get timber/PIR/plasterboard from the builders merchant, and also take that plus garden waste to the tip, 10+ times per year, in a 4 seat car that weighs under 1 tonne.
Anything truly massive, they just deliver it to me.
The day I discovered that a 2.4m 6*2 would fit inside was a very good day.
As was the one I bought roof bars.
Or ignorance made a convenient fig leaf.
This is an absolutely brilliant summary.
There are a bunch of other stl files available on wikip/media too.
It's only Virgin Media to my knowledge who does this.
Most of the other providers are happy for you to use anything that works properly for VDSL or FTTP.
Most FTTP providers fit an ONT that puts the connection back into an RJ45 ethernet connector.
Then you connect to the provider using PPPOE. Anything past the ONT, you can do whatever you like.
For most squishy remotes, you can disable the buttons by taking the remote apart, and putting tape on the underside of the rubber button.
