Hello,
On startup of my new TRB140, i have +0v on pin 3 and +12v on pin 4
When I change configurable input to output, nothing changes.
If I send a command with http post/get, nothig changes.
If I place a coil ( relay) between 12v and wire DO wire, nothing.
Also, I have activated post/get in services.
Where is my mistake,

Regards,

Serge

Hello,

Let’s start by checking if the I/O is working correctly.

  1. Log in to your router via SSH/CLI.
  2. Use the following command:
ubus call ioman.gpio.dio0 status
  1. Check if changing parameters in the WEBui for Pin 3 also affects the output of the command above. If it does, proceed.

If everything behaves correctly so far:

  • Try setting the input pin to logical high by supplying it with 8-30 V.
  • If this works as expected, it indicates that other functions should be working fine.

Additionally, try rebooting the device before starting the examination.

Best regards,

The problem was a bad contact on DO, stupid.

Where can I find cli command.
