Troubleshooting

Most problems have a simple cause. Start with the one that matches what you see.

Both must be running, on the same computer or network, with network access allowed.

Nothing is discovered in Bhairava Sense

Check these in order:

Both are running. The simulator's small window must still be open, and Bhairava Sense must be running.
A tenant has been created. Press New tenant in the simulator if you have not yet.
Same computer or same network. Bhairava Sense and the simulator must be on the same computer, or on computers on the same network.
Network access is allowed. Windows asks the first time you run the simulator. It needs to be allowed on private networks. If you are not sure it was, ask whoever looks after your computer to allow the simulator.

Then press Discover sensors again.

Use Open the simulator screen in the small window. It opens the screen in your browser again.

Use Stop and close in the small window. Closing the simulator ends the pretend tenant, so Bhairava Sense will no longer find its cabinets.
