Not able to program/communicate with esp_ir_tr module (ESP8285 all in one IR/TR) to program

[jumon]

Has anyone programmed one of these ESP_IR_TR all-in-one modules successfully? I’ve connected it to my USB to Serial board (PL2303HX chip) but it will not communicate with the device (using Chrome, which has worked fine before). I have previously programmed individual ESP01M modules for relays but with a different board. This all-in-one module uses 5V which my serial board provides (validated with meter) and I’ve reversed the TX/RX pins. I’ve also kept the jumper on when trying to program (and tried it without, disconnecting power each time).

ESP_IR_TR

Just for anyone that might try to use this module, I was finally able to get ESPHOME on it using a CH340 TTL usb module.

Here is my code that is working to dump IR codes received:

esphome:
  name: irremote1
  friendly_name: IRremote1
esp8266:
  board: esp8285
# Enable logging
logger:
# Enable Home Assistant API
api:
  encryption:
    key: "???"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Irremote1 Fallback Hotspot"
    password: "???"
captive_portal:
remote_receiver:
  pin:
    number: GPIO14
    inverted: true
  dump: all

#Transmit section once you used receiver to get codes
remote_transmitter:
  pin: GPIO4
  carrier_duty_percent: 50%

# Example to turn on/off a Hisense TV

    name: "On/Off Pioneer"
    on_press:
      - remote_transmitter.transmit_pioneer:
          rc_code_1: 0x2008

Edited: Added code block to setup transmitter with correct pin and example of one used for my Hisense TV

I like the form factor of those little things. A good way to get started with ESPHome IR.

Although I guess not having usb makes it more complex for new users.

[jumon]

Easy solution to this is to add a micro usb board (for power anyhow) and 3d print a case for both. This is what I’m doing, just have to shorten my jumpers. Since it’s updating over the air, no need to do more.

[Mahko_Mahko]

Could also cut a usb cable and either solder the wires directly or crimp on some Duponts. Especially once the initial flash is done.

I do like those usb breakouts too though.

Looking good!

Hello

Did you manage to get anything more out of these boards?

I’d like to use them as simple IR blasters, but before I go down a rabbit hole, I’m looking for guidance or warnings from you.

I found this HA post

Faking an IR remote control using ESPHome

Hi! What pins did you use for this? I tried with one pin to ground and one to the signal pin (I chose 23 on my ESP32 devkit V1) on a similar emitter, and i mostly got this: 10:08:59 [D] [remote.pronto:238] Received Pronto: data=0000 006D 0006 0000 0001 0000 0001 0000 0001 0000 0001 0000 0002 0000 0167 06C3 10:08:59 [D] [remote.pronto:238] Received Pronto: data=0000 006D 000A 0000 0001 9D89 0001 0000 0001 0000 0002 0000 0001 0000 0001 0000 0001 9D89 0001 9D89 0161 9D89 0001 06C3 10:08:59 [D] […

Does it follow on from your post here?

I have it working, yes. It’s been a long time, so I can’t remember the physical connections I made, but here’s the code. It does show the pin I use to send and receive.

Yes, they work well. You can use the module and code I put above to receive your remote codes and then use those to remotely control anything supported by adding the code below:

remote_transmitter:
  pin: GPIO4
  carrier_duty_percent: 50%

# Example to turn on/off a Hisense TV
button:
  - platform: template
    name: "On/Off Pioneer"
    on_press:
      - remote_transmitter.transmit_pioneer:
          rc_code_1: 0x2008

Thanks

That’s amazing

I’ll get to work on it
