  • KNX is indeed a protocol, but there is a whole multi - manufacturer ecosystem around it. It is mostly used in the commercial space. It is literally the ultimate smart electricity ecosystem for reliability.

    Everything that I did is done in the electrical box so you buy traditional push button switches for the walls with very thin, cheap cable, and then your lights as normal.

    It is wired originally with twisted pair bus that delivers power and data. They branched out also into wireless products also now using 898MHz bands (same as zwave).

    The protocol is very tightly regulated but everything is guaranteed to work. It isn’t wireless so it doesn’t have shitty mesh problems like zwave and ZigBee have with many devices. You don’t get bad device behaviors and disconnects with power outages. There are no shitty batteries to replace (and no fibaro zwave devices having ridiculous battery drains when outside of a +/-10C range from 20C).

    It will simply work and keep working for your lifetime, unlike many or most ZigBee and Zwave devices.

    Unlike Starfighter says, It actually isn’t that expensive for basic home users. if you do it correctly and don’t go for “everything being LCD panels”. It is much much cheaper than retrofitting every socket with ZigBee or zwave smart switches. I am fully stripping and renovating my house and it is literally about the same price as doing everything with modern teleruptors, with 10x the functionality. If you include the license, then maybe 10% more expensive.

    It cost me literally 1400€ 32 switches, 16 circuits of on/off lights and fans (or I could use them for roll blinds), and 4 dimming circuits, plus temperature and humidity sensors to smartly turn on bathroom fans. It is €30 for every Shelly wave module which would be 1000€ just for the switches alone with no dimming or sensing. Plus if you are already rewiring you house, you get to save a shit ton of money using small gauge cable with potential-less contacts.

    Don’t get me wrong, zwave is great, but KNX is absolutely king at only a marginal price premium (for standard home users, commercial focused HVAC controllers and such are expensive as hell)

    Edit: also one thing to note is that all UI elements of KNX through pretty much all the manufacturers look like they are from 2010 or earlier (and they often are). I much prefer other options or a Home Assistant tablet or something.



  • I really miss Microsoft AD configuration GUI.

    Wait, no, that sort of group you have to make through Entra, formerly Azure admin center, wait no they actually wanted a SharePoint site for the group, wait no you can’t do that through entra even though you can see the groups, you have to do that through O365 admin center, wait no you can only make a SharePoint aaand teams group there, you have to click more -> SharePoint admin center and then create a new group there, but not the default, you have to click “show more group types”, but where can you modify the members of this group? Oh you can just go back to O365 admin center to do that. Now you want to make some small access changes to the force-created email for the group? Oh well you have to go to Exchange admin center for that. Wait, not Outlook admin center? No they are named different things just to make it easy.

    Now someone who made an event involving the group is on holiday so I have to remove it, I can do that from exchange admin center right? Well actually the easiest way to do that is to log into Exchange from a power shell terminal through the GUI pop-up and terminal commands. But wait, the search for the event actually doesn’t work there ever, even with the exact name? I guess I will give myself rights to the calendar, reboot Outlook, go to the calendar, remove the event, go back to the terminal, remove my rights to the calendar, restart outlook.

    Actually, I don’t miss Microsoft sysadmin tools.






  • And this is why peertube will never actually take off outside of a Utopian future of unlimited energy and a future where everything is perfectly distributed

    Who is going to pay the hosting costs? Who is going to pay the bandwidth costs? Let’s say magic happens and the users donate enough for that. Who is going to pay the creators who that is their main source of income?

    Now what will happen when people demand 4k content everywhere, and then 8k after that? That quadruples the cost of the bandwidth and hosting costs.

    I absolutely hate hate hate subscription models and hate ads. There has to be a subscription model for any video hosting platform, and YouTube doesn’t split up into exclusivity deals like shitty steaming services to screw over the consumer for profit. So at least there is that.

    Decentralized systems work extremely well for text and even audio-based services. Video is a whole other beast, especially long form video at high resolutions.
