Feature: Y512F2 "Light button" state emulation #108

Open nistvan86 opened 4 years ago

nistvan86 commented 4 years ago

I have a Simbio 12C2 A/C (some kind of Gree rebranding, I've bought it with my apartment) which has a Y512F2 remote. Controlling the A/C works via the HyundaiHeatpumpIR module, but as soon as I send the command with this library, the display on the unit is turned off, so I don't see what is happening. There's a Light button on the remote to turn the display on/off, I guess the bit responsible in the protocol for this state is not implemented. Unfortunatelly I don't have an IR receiver to decode the raw IR data from the remote, so I cannot manually add the functionality to this library. I'm going to order an IR sensor, but maybe somebody already knows which bit is responsible for this.

I don't have access to this remote, so I also can't decode the code needed for this :(

Receiver arrived finally. It's working with the Hyundai mode of the Raw-IR-decoder-for-Arduino:

"Light" button is represented in the third byte (byte3 | 0x20 if on). I'll give it a try later to add it to the library.
