Daikin A/C remote control (Panasonic protocol)

[iz3man]

i installed tasmota 6.1.1 on one of my nodemcu, as they have enough exploited i/o pins.
connected an IR receiver to D2 and an IR transmitter to D4, and set IrSend and IrReceive accordingly.
all seems to work, and when i press buttons on my Daikin's A/C remote control, i can receive the commands, which are identified as PANASONIC protocol.

17:11:40 MQT: tele/sonoff/RESULT = {"IrReceived":{"Protocol":"PANASONIC","Bits":48,"Data":"E4000090"}}
17:11:46 MQT: tele/sonoff/RESULT = {"IrReceived":{"Protocol":"PANASONIC","Bits":48,"Data":"E4000010"}}

as this seems hex code to me, i then tried to send the exact same code to the A/C to turn it on/off, or get some reaction at all.

so in console i sent:

IRsend {"Protocol":"PANASONIC","Bits":48,"Data":"0xE4000090"}

and received

17:15:20 MQT: tele/sonoff/RESULT = {"IrReceived":{"Protocol":"PANASONIC","Bits":48,"Data":"E4000090"}}

exactly the same as what i received when i pressed the button on the remote. but nothing happens. by being able to send/receive commands on the nodemcu directly, i guess i can rule out any wiring issues.
i even moved the IR led very close to the IR receiver of the A/C just to be sure.

any idea what's going on here, and how to trouble shoot it? i'd really love to add my A/C together with automated shades and temperature sensor to home-assistant.

thanks

I'm not sure that Panasonic HVAC is supported yet - I tried using it on a Defy HVAC which I know has a Panasonic board in it and got the same result as you.

Would be interesting to see how one would make it work.

@iz3man You can check the following excellent work on reverse engineering the Daikin A/C protocol:

https://github.com/blafois/Daikin-IR-Reverse

The code is in Java, but that shouldn't be a problem to understand how it works.

[iz3man]

Excellent. Thank you!

[andrethomas]

I wonder if its Daikin specific, or if the same will work with other ones identified as Panasonic... and of course someone will need to port the code :|

What is the model of your Daikin Remote ?
Here you have already 2 different protocols (it seems)

Copied from #3228 :

In fact, it's already in the library ...
https://github.com/arendst/Sonoff-Tasmota/tree/development/lib/IRremoteESP8266-2.2.1.02/examples/TurnOnDaikinAC

It's already in the base IR library, but not implemented in the IRhvac command.
There's a couple of PR, for two other manufacturer
#3227 (Fujitsu)
and
#3274 (midea/komico)

Just a short follow-up on this, there is an excellent work done on IR and HVAC at https://github.com/ToniA/arduino-heatpumpir
It seems to be well written and extendable to other HVAC systems (besides many that are already implemented), plus it is ESP8266 ready. Might be worth a while implementing it under Tasmota...

Hello I have the exact same problem but with a Panasonic TV, I am using a D1 mini with an IR shield I can see the codes from my Panasonic TV remote, however when I send the codes via console or MQTT nothing happens. Did you found a solution?

@Jason2866 Posted some interesting info on Tasmota Chat but I have not been able to test it yet.

I tried to integrate the arduino-heatpumpir in Tasmota, and, after while I bought the first problem and first success.

Briefly, I detected a problem that does not allow the integration of arduino-heatpumpir lib in Tasmota, the problem consists in an alreay used definition of the identifiers POWER_ON and POWER_OFF; I described the problem in bullet 1 of this post.
I am not very expert of C / C++ languages so I asked for an help on the issue desciped in the linked post.

In the mean while, in my development enviroment, I bypassed the problem described in the post renaming the duplicated identifiers used in arduino-heatpumpir.

So, to intengrate the arduino-heatpumpir in Tasmota, we need to follow the following main steps:

1. rename the POWER_ON/POWER_OFF definitions in arduino-heatpumpir
   File: all files that include POWER_ON / POWER_OFF
   rename as specified below
   POWER_OFF -> HVAC_POWER_OFF
   POWER_ON -> HVAC_POWER_ON

2. copy the arduino-heatpumpir folder in tasmota\lib folder as tasmota\lib\HeatpumpIR

3. apply the changes to xdrv_05_irremote.ino file

I attach my preliminary working version of xdrv_05_irremote.ino
.

In my version of xdrv_05_irremote.ino I commented the old unused source code.

In my opinion the next steps for a full integrations are:

1. solve the issue related to duplicated definitions (POWER_ON / POWER_OFF)
2. test and complete my xdrv_05_irremote.ino changes
3. propose the integration in the tasmota to @arendst.

Hi,

Thanks a lot for sharing your ideas.

As Tasmota can't handle ALL possible IR protocols, due to flash size restrictions, we should be better implementing a RAW IR send/receive as requested at #2116.

Please, if you have further questions or ideas, do not hesitate on contacting us in the Tasmota Discord Chat. Thanks.

There’s no need to include hearpumpir.
I’ve forked the 6.3 version with the new IRRemote standard library and coded the DAIKIN HVAC driver in the xdrv_05_irremote.ino file. Details here in this thread:

Sound great, i will try asap!!! Even though it's time to turn on the heating and not A/C ;)
