Request: Send / Receive RAW IR data for any UNKNOWN device

[cyberelectronics]

Hi,
Using IRrecvDumpV2 example sketch from IRremoteESP8266 library, recommended by David Conran (Thanks!), I was able to find the RAW codes for my pellet stove IR remote control and with IRMQTTServer example sketch I played back succesfuly the RAW data to the pellet stove.

The question is it possible to implement this RAW data Receive/Transmit function over MQTT in Tasmota (no need for decode, just receiving/sending RAW data info over MQTT)?

Here is the RAW data:

Thank you!

It would have to be a special compile option as it uses an extra buffer during ir receive.

Considering....

+1 .... for an old iRobot Roomba cleaner which could be started via Alexa + OpenHAB + Tasmota-IR-Device.

We found a temporary solution :) .
My friend implemented the IRMQTTServer sketch protocols in the webapp, so now we can create/execute IR RAW codes.
The only problem is we need to use a separate device with IRrecvDumpV2 sketch on it (serial), to be able to read/learn the IR RAW codes. (example at 7:40)
Both, reading and sending RAW codes using Tasmota, would be the best solution!

+1 it would be useful for my Samsung AC. When I get IR from remote control I can see only encoded info
00:00:14 IRR: RawLen 74, Bits 37, Value 3FFF4B54, Decode -292978525
00:00:15 IRR: RawLen 74, Bits 37, Value 3FFF4B54, Decode 961051959

So I haven't any idea how to send this command via Tasmota IRsend...

I would simply like the ability to send raw data using the IRSend command. It is possible to get the raw receive data by loading and running the "IRrecvDumpV2.ino" Arduino project (part of same IRremoteESP8266 lib that Tasmota uses). See my example serial output below. I can then copy the "rawData[87]" array data that is output into the "IRsendDemo.ino" Arduino project (I also changed the "irsend.sendRaw(rawData, 67, 38);" line in the example so 67 is replaced with my array size.. 87 in my case). Then, loading and running the IRSendDemo, I am able to send my IR command correctly!

The question is, how do I convert this raw data to a command that I can send with Tasmota? The IRsend command requires a protocol to be specified, but in my case I would like to just send raw data since the protocol is unknown. Also, I believe I need to send 44 bits, whereas the IRSend command seems to limit at 32 bits, at least according to the documentation. (I was also able to send two 22 bit commands back to back which worked since it was a repeating command sequence).

Hopefully at least sending raw IR data can be added as an officially supported feature!

For anyone interested in hacking the code to send their own raw IR commands, it is pretty easy (once you have the rawData array (see example array in my previous post). I just added the following "case 0:" statement to the IRSendCommand function (in xdrv_05_irremote.ino) after the line "switch (protocol_code) {":
case 0: //UNKNOWN
irsend->sendRaw(rawData, 87, 38); break;

You also need to define the rawData array elsewhere in the code and set "87" to the correct size. Here is an example IRSend call (the values for "bits" and "data" aren't used, but these values could be used in the code to select a different rawData array and send different IR commands):

IRSend {"protocol": "UNKNOWN", "bits": 44, "data": "0"}

@jsmath this it pretty simple! Open a pull request for adding this to the official build, I think that is really useful feature!

In case of using RAW data for AC remote I have complex solution on ESP-01. I complete IRMQTTServer with IRrecvDumpV2. Easy and simple :)
