IR Climate support ZH/JT01 ZH/JT03 ( Chigo Komeco Lloyd Blaupunkt EPiK )

[marcinkowalczyk]

Describe the problem you have/What new integration you would like

Both way support for ZH/JT01 /JT03 remotes - they are used by many brands -> protocol codes https://github.com/arthurkrupa/ac-ir-mqtt-zhjt03/blob/master/include/codes.h

Please describe your use case for this integration and alternatives you've tried:

Works with https://github.com/arthurkrupa/ac-ir-mqtt-zhjt03

Additional context

Extension of supported remotes

Hi @marcinkowalczyk, would you still be interested in this? If so, would you have the ability to test this? I just implemented the ZH/LT-01 integration (another Chigo remote) and this one looks very similar. I do not have this AC myself, so I cannot test. But if you are willing, I can try to create the integration for you.

[marcinkowalczyk]

Hi,

Sure. Still running this AC

[cfeenstra1024]

Actually, after looking a bit deeper into the IR codes from the links in your original post, I think this is actually the same as the ZH/LT-01 remote. Could you give that a try?

Add the below to your config yaml to test:

external_components:
  - source:
      type: git
      url: https://github.com/cfeenstra1024/esphome
      ref: zhlt01-climate-ir
    components: [ zhlt01 ]

climate:
  - platform: zhlt01
    name: "AC"

All standard configuration parameters for Climate_IR apply (refer to https://esphome.io/components/climate/climate_ir.html)

[marcinkowalczyk]

Hi, Seems to work on both ZH/JT01 and ZH/LT01. Do you plan to add IR receiver support too?

[cfeenstra1024]

Thats great! IR Receiver is also in already. Just setup the remote_receiver section in the config file (https://esphome.io/components/climate/climate_ir.html#using-a-receiver).

I'll connect this issue to the PR of the ZH/LT-01 integration

[marcinkowalczyk]

Hi, I'm currenty testing with another unit with ZH/LT-01 (no access to JT01 at the moment)

 remote_receiver:
  id: rcvr
  pin: 
    number: GPIO5
    inverted: True
    mode: INPUT_PULLUP
  dump: all

# Configure the IR LED: this one sends commands to other devices
remote_transmitter:
  pin: GPIO14
  carrier_duty_percent: 50%

climate:
  - platform: zhlt01
    name: "zhlt01"
    receiver_id: rcvr

Can you set the dump setting to raw and send the log again?

The timing is a bit off compared to the 2 remotes I have here. You can try to set the tolerance to a higher level (default is 25%):

 remote_receiver:
  id: rcvr
  pin: 
    number: GPIO5
    inverted: True
    mode: INPUT_PULLUP
  tolerance: 55%

# Configure the IR LED: this one sends commands to other devices
remote_transmitter:
  pin: GPIO14
  carrier_duty_percent: 50%

climate:
  - platform: zhlt01
    name: "zhlt01"
    receiver_id: rcvr

When you change the logging level to verbose, it will log the reason for rejecting the received IR command. I think thats done by:

logger:
  level: verbose

When I manually decode the first log, The byte containing the temperature and mode seems wrong. I get heating at 36 degree (which I think is not possible). But I could have made a decoding error ;)

[marcinkowalczyk]

Hi,

Works fine with 55% tolerance. I will test later-on with other remotes I have

[cfeenstra1024]

OK, nice. Please let me know the results of the other remote when you have tested that.

I rechecked the decoding I did and spotted the mistake. It is indeed cooling at 25 degree according to the raw data of your log.

[ummetcivi]

This works fine with JT-01. Do you plan to merge this to master?

[cfeenstra1024]

A pull request was created January 2023. I certainly hope this gets merged soon. However, there is not much I can do about this. I think the actual merges are done by Jesse Hills.

@jesserockz : Would it be possible to pick this up?
