ESPHome and non-standard IR protocols

I have several devices that have IR remotes that don’t seem to correspond to the usual IR protocols, which is to say, the remote_receiver protocol doesn’t dump anything when I press any buttons on the remote.

Is there a way to figure out what is being sent by these remotes?

(I’m reasonably certain the configuration is right because it does dump info when I press buttons on a different IR remote that is learnable…)

Configuration follows:

    number: GPIO14
    inverted: true
      input: true
      pullup: true
  dump: all

Change frequency and duty cycle! See if that works.
