Hi,
Have new devices in the kitchen. Would like to command my Hood. Hob and Hood have Hob2Hood interface. Able to detect broadcasted infrared code. Had found several Arduino projects, where Arduino receives IR code and commands Hood through relays, it works, but I need to SEND IR codes to Hood.
IRRemote lib contains a nice function that detects IR code and provides info on how to send it out, but unfortunately, it works only for known protocols, but IRRemote cannot detect protocol. Tried to do it with pronto codes, but unsuccessful. Tried the IRMP library, It supports more protocols, but I cannot manage what should be sent out.
Probably smbdy knows which protocol is used by Hob2Hood. Had studied information on the internet, including this forum, but all that I had found - was --how to detect Hob2Hood IR signal+ questions similar to mine.
Might rephrase it to the generic question - how to translate ANY (including such with unknown protocol) IR signal to usable code, which later might be used for broadcasting command with the same result. The algorithm, how to do it, would be useful.
PS No problems with HW, have necessary sensors, etc. All works fine.
Have you considered contacting AEG through their web site >> Support >> Contact Us
Thks for idea!
Just checked. The hood is Electrolux, hob-AEG. Both support Hob2Hood and work together nicely. Heard both companies are heavily linked ...
But hood's instruction is very slim, not even really how to install, “only authorized personnel....”. Even no information (plate) on the hood with model, number etc, which is typical for such devices (but the model is LPG719W)
From that, they're unlikely to give that information, but I'll try.
Would you draw a diagram of what you have and what you want? Sending IR is not one-solution-fits-all.
This is very simple, doubt diagram would help. My hood should receive an infrared command from Arduino UNO- as the same command as hob would have broadcast it. - I would like to use Arduino UNO instead of hob. As I have all the necessary hw and it works, I think, not necessary to provide more details. Currently, I am looking at the IRRemote example ReceiveAndSend, especially at part dealing with UNKNOWN protocols...
IR code fingerprints can be different. You should as AEG.
This GitHub repository seems contain the Hob2Hood hex codes. You may have already found them.
https://github.com/alexbelgium/Hob2hood_to_Novy/blob/master/Hob2hood_to_Novy.ino
// IR commands from AEG hob2hood device
const long IRCMD_VENT_1 = 0xE3C01BE2; //Hob2hood On (level 1)
const long IRCMD_VENT_2 = 0xD051C301; //Hob2hood level 2
const long IRCMD_VENT_3 = 0xC22FFFD7; //Hob2hood level 3
const long IRCMD_VENT_4 = 0xB9121B29; //Hob2hood level 4
const long IRCMD_VENT_OFF = 0x55303A3; //Hob2hood off
const long IRCMD_LIGHT_ON = 0xE208293C; //Light on (Hood on)
const long IRCMD_LIGHT_OFF = 0x24ACF947; //Light off (Automatic after 2min)
Thank you for your response. Yes, I dug the internet, and I saw this and multiple clones. They are multiple, really. But all are based on the same. I also can confirm - these codes are right, I can catch them. But as I stated in my initial comment- I need to send them, not receive them. Unfortunately sending out the same code does not mean you can trigger hood. For example, you need to send out the code 3 times (I already figured it out) with specific time intervals between each sending, the frequency might be different, pulse... things which potentially are embedded in pronto sequences and here I am lost...
Thks, Drone Workshop always is a great source, I have seen almost all videos on YouTube. Did you have smth specific in mind to provide it to me? I saw this before, but probably I haven't paid the necessary attention to individual details.
AEG and Electrolux are almost the same. Hob2hood standard is common for both. Dropped an email to Electrolux support, but was not able to find a valid email address to AEG. Seems they pretend to have support, but in reality access is impossible
Sounds like it's time to look at the transmitted signal with an oscilloscope.
Great!. Will try...
Fantastic! It works!
By looking at your code I concluded- without you, I would not be able to get hood working. It requires deep knowledge and most likely -oscilloscope for precise measurements. Even do not know, how to pay back. The only thing that came to my mind - I will publish my final code, where this functionality is embedded in practical application. Big thanks to you!
Thanks for testing!
And please publish your code (maybe on Github) so I can include a link to it in the readme for this example
