Support for Hitachi RAS-70YHA3 (remote RAR-3U3)

[jeef3]

I am trying to add support for my Hitachi RAS-70YHA3 heatpump with remote RAR-3U3. I forked your repo and started an attempt (you'll have to forgive me, I'm not a c++ developer) a few months back, but I struggled a bit. I called it HITACHI_AC296.

My attempt is based on someone else's research on the same protocol. Using what I learnt there I was able to send working signals, I just wasn't able to get it into IRremoteESP8266 properly.

At the time I did not know about auto_analyse_raw_data.py, so I will give that a shot. I just wanted to open this ticket to track progress and have a place for guidance 🙏.

You seem to have been doing quite good.
Start with https://github.com/crankyoldgit/IRremoteESP8266/wiki/Adding-support-for-a-new-AC-protocol
Get the receiver and sending logic in place.
For an AC it is best to record the temperature range and post the raw data.
That is from 16-32 Degrees C or whatever the remote does without changing any other setting.
This gives us the best way to arrange the receive and sending functions for easy conversation.
(it also serves as documentation if anyone ever needs to go back and check the protocol)

The values you have seem to match the generic IRrecv::decodeHitachiAC only a "new number of bits"

FYI, the changes mentioned above have now been included in the new v2.8.2 release of the library.

I'm having some troubles with HITACHI_AC296 detection.
Remote is RAR-3E1, Hitachi RAS-10EX2 -- It gets detected as HITACHI_AC296 but not all the time. I've tried adjusting kTolerancePercentage & kTimeout without any improvement:

How to get rid of those? Does kHitachiAcMinGap has anything to do with it?

Also, looks like 2 of the modes aren't recognized (took me a looooot of tries to be able to extract a "working" match:

Here are the mode we have had reported to us:

IRremoteESP8266/src/ir_Hitachi.h

Lines 345 to 353 in 00b27cc

	// Mode & Fan
	const uint8_t kHitachiAc296Cool = 0b0011;
	const uint8_t kHitachiAc296DryCool = 0b0100;
	const uint8_t kHitachiAc296Dehumidify = 0b0101;
	const uint8_t kHitachiAc296Heat = 0b0110;
	const uint8_t kHitachiAc296Auto = 0b0111;
	const uint8_t kHitachiAc296AutoDehumidifying = 0b1001;
	const uint8_t kHitachiAc296QuickLaundry = 0b1010;
	const uint8_t kHitachiAc296CondensationControl = 0b1100;

Unfortunately the make/model you are dealing with here has more mode options than our library can easily report.

For the modes -- const uint8_t kHitachiAc296Cool = 0b0011; -- how is "0b0011" derived? I.e. How can I get it from my remote to add to supported.

How to get rid of those?

You can disable "UNKNOWN"s using:

IRremoteESP8266/src/IRremoteESP8266.h

Lines 113 to 116 in 00b27cc

	// Semi-unique code for unknown messages
	#ifndef DECODE_HASH
	#define DECODE_HASH _IR_ENABLE_DEFAULT_
	#endif // DECODE_HASH

i.e. Set DECODE_HASH to false
or
use setUnknownThreshold()

It's a binary literal. i.e. Base-2. e.g. 0b0011 == 3

Also, a good "issue" ettiquite is to NOT add information about a new problem to an existing "closed"/resolved issue.
You're dealing with a different remote and A/C, it's not "the same thing", nor is your issue related to adding support for a complete new protocol.
