Need example for Turn ON Hitachi AC

[viv1ag]

Dear Developers,

Could you please add the example for "Turn On Hitachi AC" as other AC examples have been added.
#HelpWanted

[crankyoldgit]

Assuming you've got a Hitachi A/C unit that uses the 28-byte message size, you should be able to pretty much just edit the TurnOnToshibaAC.ino example code by search & replacing the following:

• Toshiba -> Hitachi
• TOSHIBA -> HITACHI
• toshiba-> hitachi

And the example will probably just work.

[crankyoldgit]

Note: You will need to be using the current head of the master branch of this library, or a version greater than 2.5.2 for that level of Hitachi support. (i.e after 9a5e2ae)

Using IRrecvDumpV2.ino; I got following serial print:

I am using latest code from master branch only. This 108 bit data will not be worked with Toshiba example file.

[crankyoldgit]

Sorry, per comments in the code & PR #563 there is only detailed Hitachi Protocol support for the 28-Byte HITACHI_AC protocol variant. i.e. state[28]
There is no detailed support yet for the HITACHI_AC1 / 13-Byte protocol variant. i.e. state[13]

So, in order to turn on a unit that is using the HITACHI_AC1 protocol, you'll need to use code something like the following for now:

uint8_t state[13] = {0xB2, 0xAE, 0x4D, 0x91, 0xF0, 0xE1, 0xA4, 0x00, 0x00, 0x00, 0x00, 0x10, 0x78};
irsend.sendHitachiAC1(state);

If you can successfully analyse and decode the 13-Byte protocol into it's various parts, we can possibly add full support for that variant.

Hey @viv1ag, How are you going with this? Did it work for you?
As it's been about two week, if we don't hear anything from you soon we are going to assume this issue is stale and mark it closed.

[crankyoldgit]

Marking this Stale. Closing for now.
