Optoma hd141x projector IR codes

Hi, first post here, so i hope it’s in the right topic.

I have lost the remote to my Optoma HD141x projector.
Does anyone by chance have the IR codes so i can use them with my IR blaster?

Hi,
I just finally got some new m5stack toys all set up and recorded all of the codes from my HD141x remote. I dumped them with the following settings:

remote_receiver:
  pin:
    number: GPIO32
    inverted: True
  dump: raw
  buffer_size: 80000
  idle: 50ms # HD141x remote uses pretty long gaps

Here’s my spreadsheet with all of the codes: Optoma HD141X Remote codes - Google Sheets

Right now I’m just using a projector power template switch. Note that I’m using an older version of the power off signal, recorded with the default timeout so it comes out in 2 segments. Seems to work fine:


switch:
  - platform: template
    name: Projector Power
    icon: mdi:projector
    assumed_state: true
    optimistic: true
    turn_on_action:
      - logger.log: "Transmitting power on signal"
      - remote_transmitter.transmit_raw:
          carrier_frequency: 38kHz
          code: [8960, -4459, 566, -547, 565, -1658, 566, -547, 565, -548, 564, -1658, 566, -1658, 565, -548, 565, -570, 542, -1658, 565, -571, 542, -1658, 565, -1659, 565, -571, 541, -571, 541, -1659, 565, -1659, 565, -571, 541, -1659, 565, -571, 541, -571, 541, -571, 541, -571, 541, -571, 541, -571, 541, -1683, 541, -571, 541, -1683, 541, -1682, 542, -1682, 541, -1683, 541, -1683, 541, -1683, 541]
      - logger.log: "Transmitted power on signal"
    turn_off_action:
      - repeat:
          count: 2
          then:
          - logger.log: "Transmitting power off signal"
          - remote_transmitter.transmit_raw:
              carrier_frequency: 38kHz

          - logger.log: "Transmitting power off signal part 2"
          - remote_transmitter.transmit_raw:
