  • I wouldn’t expect HDMI 3 given the HDMI group are openly hostile to open source implementations of HDMI 2.1.

    It just takes a company with sufficient market power, like Valve, to get involved. For example Android had this same problem in the early days, then Google realized that their OS required it for market adoption and found a way to get it done.

    I understand that it may not be possible but that doesn’t stop me from wanting it. :)


  • I don’t know if there’s any pre-built scripting out there (yet) for this but it’s relatively straight forward in Windows to use powershell and either look in the registry for the assigned dhcp options ( HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp\Parameters\Options) or check the routing table for illogical routes.

    Assuming that you aren’t using split tunneling you could also have powershell check your external IP address for the expected result.

    Another possibility is to grab the dhcp test tool from Github, run it in non-interactive mode and then parse it’s output. Something I find VERY interesting is that Andrey Baranov specifically added Option 121 to that tool in March of 2023!

    With any of those it’s a matter of what you want to have happen when you detect the problem such as warning the user and disconnecting the vpn or attempting to mitigate the problem by reconfiguring the routing table.

    I should point out that Option 121 is a legit thing and it does have valid uses so you can’t assume something nefarious just because it’s being used.

    I’ll probably be scripting up a remediation over the next few days, I’ll try and remember to come back and share what I did.




  • What are the missing pieces you’re still looking for?

    The addition of JF or Plex, even with a Steam Dock, doesn’t turn a Steam Deck into a user customizable, privacy respecting Xbox.

    For starters it needs integrated streaming apps. I don’t WANT to have to use a web browser to access streaming content. Next up those streaming apps need Audio and Video support for 4K resolutions, Dolby Vision / HDR, and Dolby Atmos. My Wife doesn’t want to watch Outlander in 1080p with stereo sound on a 65" 4k television and I don’t want to do it when I’m watching shows on Disney Plus.

    How about an HDMI 3.x port? (Steam Dock is only 2.x).

    It needs support for a normal tv style remote control. Game controllers are great but I’ve yet to find a half decent one that has volume and mute buttons.

    The last time I checked a Steam Deck wouldn’t automatically start in a 10’ interface.

    Please understand that I’m not bagging on the Steam Deck with these comments. It’s a damn capable device for mobile gaming but it wasn’t mean to be an HTPC and because of that its never going to function quite right if you try and make it be one.

    An Xbox Series X absolutely murders a Steam Deck as an HTPC when used with commercial services but its not user customizable nor privacy respecting. That’s why I want Valve to bring back Steam Machines.


  • You have to use your internet-facing programs in a VM in Windows to achieve the same effect

    Eh, there’s 20 different ways to detect DHCP Option 121 fuckery and once you know it’s happening its fairly trivial to stop. Any VPN client worth its salt will be updated in 60 days or less to fix this and existing VPN clients can be hardened against TunnelVision with some fairly simple scripting.

    It’s a serious vulnerability but it’s hardly the unfixable world ender that the media has made it out to be.











  • I got it setup with MQTT after about an hour of futzing but I still need to wire it to my GDO.

    I was really hoping to just connect it to WiFi and straight into home assistant without messing with a broker.

    If you have a Sec 2.0 opener then you will probably be able to. Just be sure to check before you order.

    I just hate that Chamberlain pulled what they did.

    Me too, although I never used MyQ. I already have a fully functional Z-Wave setup that I built myself before ratGDO existed but there was so much hype around this thing that I figured I’d get one and see what it was about.


  • I had some time to play with it and I’m underwhelmed. I’m not sure how I overlooked this before ordering but if you have a Security 1.0 system like I do then you MUST use MQTT. The ESPHome firmware isn’t compatible with Sec 1.0 at all.

    I’ve also managed to lock it up (device becomes unresponsive) three times while trying to configure it for MQTT. I can flash it just fine but there’s something I’m missing with the MQTT setup which isn’t surprising since it’s all new. I’ve never had to use it before and have zero idea WTF I’m doing.

    I’ll get it going but right now I’m wondering if it’s worth the effort.
