Request: Can the web interface be updated to show the PWR and HDD LED state.
Cheers.
Hello,
May I know the reason why you request to add the LED of PWR and HDD in UI?
If the controlled device has been powered on, just check the task manager to learn more about the disk status.
For the HDD, just a feel-good to see things happening.
For PWR, it would be good to know, in the cases of where the screen is blank and the system is booting during an OS/BIOS upgrade, where pressing the power/reset button again could have the effect of a shutdown which could be disastrous.
Another edge case would be after a power outage and the UI shows a blank screen, is the box really powered off.
Cheers.
It can't be done.
Is this really not possible? I feel it's a very important feature. Coming from PiKVM it was always handy to be able to tell what is going on from a distance. For instance, the server is powered on but nothing is being displayed - I can tell that there is something more serious going on, could be a hardware failure on the server. If I can't even tell if the server is actually powered up without visiting the site, that is a problem. Has the power supply failed? I can't tell with Comet+ATX. With others I can confidently say it is definitely powered on and this is what I need to look into next.
Another instance could be a hdd failure slowing a server to a crawl. I've encountered this before, the server is taking an age to boot but I can see there is hdd activity. I might choose to wait it out and see if its boots so I can investigate further. With Comet+ATX I can't tell whats going on. Conversely, I might see that there is no hdd activity at all and try rebooting remotely.
Just two little indicators showing power and hdd status is all that is needed here. Are you saying it's a hardware limitation in that you aren't able to get that state through the ATX control board?
The implementation method of the ATX board determines this. Unless the ATX board is implemented via GPIO (connected through an interface that resembles an Ethernet port, as seen with other brands).
Are the PLED+ and HDLED+ lines routed to input-capable GPIO pins on the CH552T?
The PLED line is conneted to CH552T, but the HDD LED not.
Thank you for confirming that. Would it be possible to expose the power status in the Comet’s web GUI, and would that require a firmware update? Also, do you think future revisions of the ATX controller could connect the HDLED+ line to the CH552T as well? That would really complete the package.
I will check with our team. Right now we don't have the plan to upgrade the ATX hardware, but I will add it(HDD LED) to the request list.

Great! If the software (WebGUI) can display power LED status it would be of great help for headless server diagnostic when no HDMI display is happening. At the min we would know sending the power to the ATX power is powering up the whole system. Thanks!

Just wanted to add my vote to this - I just connected up my ATX board today and I was disappointed to see that the power LED status cannot be seen using the web interface. Thus if the server crashes and there’s no video output, I have no way to tell if it’s on when I’m not physically present. I do not need the HDD LED, but I would really value if the power LED status can be shown on the web UI.
If you just want the power LED and can tolerate it not being in real-time, that should be achievable.
I think this one is important 
If a user forgot to turn off his main monitor and uses displayport, then the kvm will never get a screen, the purpose of knowing headless if the pc is powered on or off becomes very crucial.
this can happen also if the kvm was a second hdmi connection.
My issue is, with kickstarter I added a atx board but now I'm asking myself if I should remove this addon for a 'upgraded' version, or would something like this still be possible to archieve?
The most important for me is seeing the power state.

Oh absolutely. Last night I was experimenting with the terminal interface to the RM1, and I realised that I can run atxpower /dev/ttyACM0 power_state to get the power status. Posting this here in case it helps anyone else, but if there was a way to get this through the web interface that would be even simpler. If it’s not real-time I’m ok with that - I guess the user story is something along the lines of “as a user, I want to be able to validate that the device power is actually on to help me in the event that I’m not seeing any video and I’m not physically near the device”. I see it as more a troubleshooting tool (and comfort that everything is working as it should) and not something that needs to be in real-time.

In fact, it would be nice to add something like Power LED Status: ON/OFF (updated xx minutes ago) and the "Update" button next to it.

should be add in 1.7.0 (1.6.0 only for comet pro so it has been skipped)
