Off command for Airwell AC

[zevele]

Version/revision of the library used

v2.8.4

Describe the bug

Not really a bug - more a questions. I'm using IRMQTTServer with Home Assistance. I've used IRrecvDumpV2 to recognize my remote control (RC-3) and it was recognized it as an Airwell protocol. Everything seems to work fine. The thing is that the power control is actually a toggle (same code is sent to turn and off the unit). This can also cause confusion with the IRMQTTServer control - , if the unit misses one power toggle command the unit state in IRMQTTServer is wrong.
Is there any way to solve this? if there was a dedicated "off" command - it could help.

I have found in the SmartIR project in this discussion, a mention about a dedicated "off" command. It is also documented in this json config file

I think it might be the same unit, but I couldn't understand how to convert it to IRRemoteESP8266 format to test it on mine.

What brand/model IR demodulator are you using?

Airwell

Sorry, I don't know how to convert their format to anything we can use, off the top of my head.

Yep, Power "toggle" bits/commands are a bug-bear for automation. As you've noticed, it's easy for things to get out of sync. If you do find a solid way to turn off or on the device, we can move away from using a toggle.

For any A/C manufacturer out there reading this. Please for the love of people's sanity, let us have discreet power control bits or at least special commands. Toggles suck.

Thanks for the quick reply (and for moving the post to the correct location). I'll try contacting the SmartIR team, maybe they could help me convert the command to something readable by IRremoteESP8266

Okay, I found someone who described how to parse the Broadlink format and converted these codes. Unfortunately they are all identical and probably the same as found here for the Airwell.
If anyone is interested this is the python code I used to convert the string to raw format:

import base64

command64 = b'JgC+AGODPkE/IR8hHyIfIh4iHiEfIh5BPyEfIR8hHyIeIR8iHiIeIR8iHiEfIR8hHyEfIR8iHiIeIR8iHiEfQT8iYIM/QT8hHyEfIR8hHyEfIR8hH0I+IR8hHyEfIh4hHyIeIR8hICAfIR8hHyEfIR8hHyIeIR8iHiEfIR9BPyFhgz9BPyIeIR8hICAgIB8hHyIeQj8iHiIeIR8gHyEfIh8gHyIfIR8iHiEfIR8hHyEfIh4iHiEfIR8hH0I+IYEADQUAAAAAAAAAAAAA'

byte_list = list(base64.b64decode(command64))

data_len =int.from_bytes([byte_list[2], byte_list[3]], byteorder='little')

print('0 (Command Type): 0x'+format(byte_list[0], '02x'))
print('1 (Command Repeat): 0x'+format(byte_list[1], '02x'))
print('2-3 (Command Length): '+str(data_len))

res=''
i = 4
while i < 4+data_len:
  if byte_list[i]==0:
      pulse = int.from_bytes([byte_list[i+1], byte_list[i+2]], byteorder='big')
      i+=3
  else:
      pulse=byte_list[i]
      i += 1
  if byte_list[i]==0:
      space = int.from_bytes([byte_list[i+1], byte_list[i+2]], byteorder='big')
      i+=3
  else:
      space=byte_list[i]
      i += 1
  res=res+str(pulse*8192//269)+','+str(space*8192//269)+','
print('IRremote Raw IR message: 38000,'+res)
