[Resolved]Headset recognized, but not controllers or lighthouses

As the subject says; I received my 5k+ headset. I’ve had a working Vive for over a year.

I updated my nvidia driver to 417.71 (current version)

Installed the latest PiTool

Ran PiTool room setup. Headset appears, but controller and lighthouses are shown as disconnected.

I tried to run SteamVR room setup, but only the headset appears in the device list. My controllers and lighthouses are no longer visible in SteamVR.

I can see a space landscape in the headset. I can turn my head, but my POV is locked to the ground. I cannot move vertically or horizontally.



Did you perform pitool room setup? & to confirm in pitool is lighthouse tracking box on?

Yes, I performed pitool room setup.

LH v1.0? If so do they see each other?

You might need to wake up lighthouses?

Yes, they are 1.0. I’m not sure how to ‘wake them up’, but I have unplugged them and plugged them back in. Lights are green on both. Restarted PiTool and SteamVR. No change.

Update: I disconnected the pimax and reconnected my vive. Lighthouses and controllers are recognized and operational in SteamVR. I disconnected my vive and reconnected my pimax and the controllers and lighthouses are not recognized nor operational in either PiTool or SteamVR.


@park likely have dome good ideas as may @spamenigma.

Seems to crop up this for some, unsure on the answer as yet.

Lighthouses are detected via sensors only, there’s no Bluetooth connection. Some with a single lighthouse have had an issue where it doesn’t work until you move the HMD around 2M+ away, not sure if the same applies with 2x LH?

Various other tricks have been tried for LH issues such as:

  • Testing different USB ports.
  • Pc restart (sometimes twice!).
  • Reseating the cable in the HMD (pull>push).
  • Stop/start of ‘PiServiceLauncher’ Service.
  • Deleting contents of %localappdata%\Local\Pimax\runtime\config\lighthouse and restarting the ‘PiServiceLauncher’ or pc.
  • Trying USB connected in a powered hub.
  • Ensuring motherboard drivers including USB controller drivers are up to date.
  • Power on HMD whilst in full view of the lighthouses (but not too close).
  • Logging a support ticket with Pimax (on the website) for Teamviewer session to adjust config on HMD (something extra to standard firmware update).

@Davebobman this might be good in your troubleshooting.


Did you manage to get this fixed? As I seem to have similar issue…

Exactly the same issue, funny thing is that it worked once (after cycling lighthouse power) and then never again

Which headset did you receive? Have you checked the wiki in the 5k 8k directory?

I have the 5K+, i have scoured everything, the only time it worked was when i followed these steps: https://community.openmr.ai/t/how-to-solve-disconnect-or-not-tracked-of-headset-base-station-controller-randomly-image-follow-head-although-not-use-base-station-pitool-91/11776 this was on the first day i had the headset. the best i could do after that was one lighthouse tracked and one controller, after that i can’t get anything going except the headset.

Will see what I can find later on light house issues


Have you had any luck with this?

Did you create a ticket on support:https://pimaxvr.com/pages/feedback

I’m unable to access support site as password reset is disabled for my account. I have contacted support@pimaxvr.com and @alan.sun directly by email.

Have not had much luck. I have a support ticket open from a week ago but last time i heard anything from that was to delete the lighthouse files, which i’ve done dozens of times. The only thing that has shown any promise was to run my Vive fully connected and then fire up the Pitool, this way the lighhouses on there show as blue, with only one tracked though, the only thing is that the headset reports as not being tracked.

So I “improved”(?) from this:

this this:

I’m giving up for now until the next version of Pitool comes out or I hear from my support ticket.

I’ve come to the conclusion that it’s not pitool related but something with the headset itself… But no worries as we will be contacted ASAP :wink:

One strange thing I noticed is with my main PC if I reboot the HMD manually to DFU mode it doesn’t stick. It cycles all the lights for few rounds but then it reboots… I’m not sure if this is related to the lighthouse tracking issue or not but now I’m starting to think that if the DFU mode on this PC isn’t working correctly there might have been something gone wrong in the pitool flashing process even tho it stated success.

On my other PC manual DFU mode is working just fine. I’m thinking of doing one more firmware flashing cycle using that one instead. Anyone know where could I find the earlier versions of fw/pitool?
