How to add more models?

[bserem]

I just found this repo, and the idea looks amazing.

I have two Toshiba AC split type Units (RAS-10G2KVP-E RAS-10G2AVP-E and RAS-13G2KVP-E RAS-13G2AVP-E) that I would like to control. With the simple.ino sketch provided by this library they do not seem to react, so I guess I'll probably need to add support for them.

I have successfully managed to decode other remotes (amplifiers, tvs) with https://github.com/z3t0/Arduino-IRremote library. It reads the codes sent out by the Toshiba remote two (WH-TA01EE, first one here http://www.toshiba-aircon.co.uk/assets/uploads/product_assets/EU_Wireless_Remote_controller_20150120.pdf) but when I try to send them the AC does nothing.

How can I proceed so that I improve this library to support the afforementioned models? I have an IR receiver and transmitter, I do not have the adafruit shield. Maybe I could help decode the remote and/or unit.

Thanks

PS: Here is what I get when I press the on/off button (first for on, second for off):

If you read how he made the libraries you will notice he uses the raw decoder to analyze the signal,do that and you can make your own library.

[bserem]

Thanks for the reply! I do not really get what you mean by "how he made the libraries", I still can't decrypt how he made them :D

What is different in the case of my remote compared to the remote used in this library, is that the array consists of 179 elements instead of 144. Also the transmission code is F20D05FA instead of F20D03FC, but I do not get where this is set either.

in the meanwhile I just managed to power off my AC unit using a RAW command:

  int khz = 38; // 38kHz carrier frequency for the NEC protocol

  unsigned int  irSignal[] = {4350,4300, 600,1550, 550,1600, 550,1600, 550,1500, 700,450, 600,500, 550,1500, 650,500, 600,450, 600,500, 550,500, 600,500, 550,1550, 600,1550, 600,500, 550,1600, 550,500, 600,450, 600,500, 600,450, 600,500, 550,1600, 550,500, 600,1550, 600,1550, 550,1550, 600,1550, 600,1550, 600,1550, 600,450, 600,1550, 600,500, 550,500, 600,500, 550,500, 600,450, 600,500, 600,450, 600,500, 550,1600, 550,500, 600,1550, 600,1550, 550,1600, 550,500, 600,450, 600,500, 600,450, 600,500, 550,500, 600,500, 550,500, 600,450, 600,1550, 600,1550, 600,1550, 600,450, 600,500, 600,450, 600,500, 550,500, 600,500, 550,500, 600,450, 600,500, 600,450, 600,1550, 600,450, 600,500, 600,450, 600,500, 600,1550, 550,500, 600,450, 600,500, 600,1550, 550,1600, 550,500, 600,1550, 600,450, 600,500, 550,1550, 600,500, 600,450, 600,1550, 600,1550, 600,500, 550,1550, 600};  // SAMSUNG F20D05FA  Serial.println("irSignal");
  irsend.sendRaw(irSignal, sizeof(irSignal) / sizeof(irSignal[0]), khz);

irSignal array is from the first post, a simple copy paste. My second arduino, which works as a receiver for debugging purposes, doesn't get the same numbers, but the command works. Some sort of error correction maybe?

[ToniA]

Can you try this one out: https://github.com/ToniA/Raw-IR-decoder-for-Arduino

I have done everything by reverse-engineering. First by writing a receiver module for this receiver sketch, and then by writing the transmitter library.

[bserem]

Hurray, I got a responce!

This code https://github.com/ToniA/Raw-IR-decoder-for-Arduino was not working on the Arduino Mega. It took me some time to realize this.

On the UNO I get proper replies (you can see on/off below). Modes 1 and 4 seem to give correct results.

I know I'm still far away from actually decrypting all these, but its a start. I'm gonna take a break and continue later.

Strange that it's not working on the Mega... That's what I'm using all the time.

[bserem]

It runs, but after I select a brand it goes on and on even with no data from the IR Receiver. I might have some time next weekend to check whats going on with it.

[bserem]

So, after pressing some buttons on the remote to get it close to what the decoder expects, I got this reply:

Looks like a Carrier protocol #1
FAN: AUTO
MODE: HEAT
Temperature: 23
ModeFan  11000000
Checksum 01000110 matches

Airflow direction (when set) doesn't resolve to a known protocol, but it looks like for normal operation I could go with Carrier. I know that Carrier and Toshiba work together (I think), so maybe the IR codes are indeed close.

Moving on, I adapted the Hisense demo file to send CarrierNQV commands and my AC unit responded. My means of verifying it got the correct temperature is the "double beep" it does when I set the temperature on 24 degrees (single beep on anything else).

It took a day, but it was worth it. Shall I prepare a PR with documendation improvements about Toshiba Daiseikai units (RAS-10G2KVP-E etc) and a sample sketch?

PS: on a side note, my IR led doesn't seem to be as powerful as the one found on the remotes. I need to get it about 1m for the unit for it to respond. @ToniA do you have any experience on that issue?

Or maybe it is the different PAUSE SPACE, HEADER MARK, HEADER SPACE, BIT MARK, ZERO SPACE and ONE SPACE from CarrierHeatpumpIR.h and my remote.

[ToniA]

Thanks for the PR, I'll take a look at that when I have some spare time.

Yes, the IR led is not very powerful, I also get 1-2m range. You'd need an IR blaster for longer range.

[bserem]

I'll try to find this one https://www.adafruit.com/products/387 in my market, and then search into the irblaster thing.

Thanks for the support. I guess we can close the issue?

[renato-bylyk]

I had the same issue so i connected the IR led through an 2N2222 NPN Transistor,it acts like a boost.
