IR Commands using TSOP IR

[joemadd3n]

Connected the TSOP IP to the signal pin of my Midea AC unit for turning off the display.
I have my ESPHome configured with remote_transmitter on GPIO13 with a duty cycle of 100% however, it doesn't turn the display off.
I can obviously turn the display off with the remote, confirming the functionality is there.

What's the best way to debug the issue here please?
I have the longer style USB stick as pictured here:
https://github.com/dudanov/iot-uni-dongle/raw/main/images/tsop_stick.jpg

I possibly have a similar problem. I have included the necessary part in the configuration file

remote_transmitter:
  pin: GPIO13                       # For iot-uni-stick the value needs to be GPIO13
  carrier_duty_percent: 100%        # 50% for IR LED, 100% for direct connect to TSOP IR receiver output

as well and

sensor:
  - platform: homeassistant
    name: temp_control_ac_by_external_sensor
    entity_id: sensor.external_temp_sensor   # Sensor from Home Assistant
    internal: true
    filters:
      - throttle: 10s
      - heartbeat: 30s                       # Maximum interval between updates is (default): 2min
      - debounce: 1s
    on_value:
      midea_ac.follow_me:
        temperature: !lambda "return x;"
        beeper: false                        # Optional, beep on update is: true - silence is: false

but the Follow Me functionality does not seem to get triggered unless you trigger it with the (real) IR remote controller after which it works nonetheless and temperature values of the external temp sensor are used by the Midea AC, which can be confirmed by looking at the climate entity.
This is with the small USB stick and I wired IR- to the IR receiver's signal, like Sergey suggested.
I am probably missing something.

Hey there,

this works for me on Simando SMND-PAC-12. Maybe this helps others with your dongle!
tsop out pin
(
how to find data pin on unnamed tsop

• multimeter in voltage mode
• probes on the outer tsop legs
• send IR command
• got voltage spike? you found data pin and ground
• if not you may need to change probe location on your device
• hint: there should be a RC circuit between VS and Ground

)

is connected to D2 on my NodeMCU.
now the remote control can be used as temp sensor (replacing the reading from the mono block) and to c ontrol the unit. Also HA can control the device now. perfect! thanks for config_example!

hint: you could also use platform: midea_ir, but this class does not support follow_me function. There is a open feature-request

Can you use IR and UART functions at the same time (on the code side of things...i know that you can't control the AC two separate way at the same time)? Or you can use it only IR or UART? Because i want to setup sometimes the follow me temp too.

If you use a standard Nodemcu and use one pin for ir send and one for ir recieve, you can control the AC with IR remote and Homeassistant at the same time. Homeassistant also recieves info about changes made by the remote.
AFAIR with the dedicated iot dongle one could use the same pin for IR send/recieve.

Did you solved follow me feature with Sergey dongle?

Hello KuChar91, yes I did, and the solution is running beautifully. I will add my config file below, maybe it helps.

I am trying to connect to the TSOP data pin to send IR commands. But when I connect it the TSOP doesnt work anymore. If I try the actual remote nothing happens until I disconnect the wire that I soldered to the data pin.
I am using a standrad esp-01 and connecting GPIO2 to the data pin. Any idea if I need to do any specific wiring (add a resistor or use a level shifter?)

Quite unsure what you try to do. TSOPs are receivers.
If you want to receive with the tsop and it seems line is blocked all the time, did you try inverted mode?
Voltage level is 3.3v so no shifter needed. Bute there are recommended application circuits found in the datasheet or on google, which usually use atleast one resistor and capacitor
