Control of Toshiba R410 Heatpump

[beersmith]

Hi,
I have a Toshiba R410A Heatpump that I would like to control remotely to turn on the heat a day before arrival. I usually use Domticz and Arduino Pro Mini and have not found any solutions to this. Do I need to decode the remote Control? Thanx for hints on this.

Hello, did you have a look at @ToniA 's library here ? Your heat pump is not in the list but checking the code for the other Samsung models should help you get started.

I can also recommend Toni A's library

Hi and thanks for the tips so far, it got me started and busy
I have tried to make it as simple as I can since in the first run. I only want to send one command (from Domoticz) to my Toshiba R410A Heatpump . That is the power ON command.
I have built a decoder for tapping off the remote the HEX code the remote control sends. (I have not yet retrieved the codes of my own heatpump since it is in the cottage in Härnösand) I have tried it with a friends HeatPump remote and the serial monitor is displaying code like
7200000
FFFFFFFF
24EFEA7A
EF1767BE
FFFFFFFF I don’t know is these (Panasonic) codes are correct but it seems I have a means to listen to my own Toshiba remote when I get to it.
(sketch came from answer in https://arduino.stackexchange.com/questions/3926/using-vs1838b-with-arduino )
Next step was to try to “steal” something that I could work with as a start. I may have grossly overcomplicated things here because I started out with
https://www.mysensors.org/build/heatpump
that links to
https://github.com/ToniA/arduino-heatpumpir
This holds a lot of bells and whistles that I don’t (think I) need. I also don’t have a sensebender as in the instructions but build on Arduino Pro Mini.
I get loads of compiling errors and thus I try to disable the things I think I don’t need in order to be left with a way to send the Power ON command to my Toshiba R410A from Domoticz.
I read on https://www.mysensors.org/build/heatpump :
“The commands can be given as the payload of the V_IR_SEND message. As Domoticz does not really support this too well, another way (in Domoticz) is to give a value to the V_TEXT sensor, and trigger the send by turning the V_LIGHT switch on. See the Domoticz project page for more details (especially the Lua script to connect the virtual switches into the V_TEXT / V_LIGHT sensors).”
So I guess this function is what I need along with a compileable sketch for the Arduino Pro Mini to “drive “ the IR diode. Hopefully I will also be able to decode the Toshiba Remote so that I may contribute something as well.
Any hints for my strategy ?

Did you take a look at the mqtt IR remote i posted in the Projects section? There is a link to libraries for different brands

@gohan Hi, Sure did look into it. Since I am somewhat inexperienced yet, I opted to start with the
www.mysensors.org/build/heatpump since I am a little bit more aquainted with that. But it contains way more than I need so I have a hard time getting my head around it. I travel to "see" my heatpump this weekend so I stay on one track until next week. Thanx again for your comments.

@beersmith
I can still recommend to use wemos d1 pro mini with espeasy and ToniA's plugin.
if you remote isn't supported, then create a circuit to measure the raw ir
I believe that the easiest and right approach, as you then can control all your heatpumps functions easy
