I recently bought a Home Assistant 14.4 setup running on an HP T630 Thin Client (Quad-Core, 32GB SSD, 8GB DDR4). Everything was working fine—I was accessing it through port 8123 without issues.
After making some changes (possibly to the configuration.yaml or network/SSL settings), I can no longer access the web interface via port 8123. However, I can still ping the device from my network, so it’s definitely online.
The problem is, I don’t have a monitor or keyboard connected to the device, so I can’t see what’s actually happening on it.
Is there any way I can access or reset it remotely (via SSH or otherwise)? Or any way to roll back the last config without physical access?
I’m pretty sure I didn’t install or set up any SSH add-on in the past. I just used the File Editor to make changes to the configuration.yaml, and now I can’t access Home Assistant anymore — not even locally via http://192.168.0.23:8123.
I ran a port check from my PC using PowerShell: Test-NetConnection -ComputerName 192.168.0.23 -Port 22
And it shows: TcpTestSucceeded : False
So SSH seems to be closed, and I can’t connect. I also checked port 8123 and it’s closed too, which suggests Home Assistant isn’t running or the config broke it.
Unfortunately, I don’t currently have physical access to the machine running Home Assistant — I can ping it, but that’s it.
Does this mean I’m completely locked out until I can physically get to the device and fix the config?
I connected a monitor and keyboard directly to the device running Home Assistant. From the console, I fixed the configuration file and restarted Home Assistant. Now everything is working again and I can access it as normal.
