Zenith AC brand #80

Open kilbamoo opened 5 years ago

kilbamoo commented 5 years ago

I have a zenith ac unit. HeatpumpIR does not show any compatible devices. So I put the RAW IR decoder for arduino on my uno and connected a ir receiver. I was able to capture something, however I dont know what exactly to do with it. This is the serial output under option 4 (Hyundai). Option 5, Samsung, will output similar data. The output shown is when I press the power button 'on' from the remote. How do I create a decoder module?

The raw decoding looks fine. The next step is to try to understand the structure of the message, i.e. what is the meaning of each bit in the message. I just systematically go through one change at a time, and try to figure out what change corresponds to a change in the bit pattern.

There is also a possibility to just record raw samples and play them back: https://github.com/ToniA/arduino-heatpumpir/blob/master/examples/rawsender/rawsender.ino

I don't think this a good decoding. Only 3 bytes. Seems like the timings was wrong or carrier issues. @kilbamoo try a few more decoding to see if bytecount remains the same. Also try other modes of sketch operation.
