How Obniz control the IR transmitter and talk to different brands of Air-conditioner?

[Marcos Tang]

Hi,

I am new to Obniz. I am trying to use Obniz Cloud to control my air-conditioner at home. My plan is to use a temperature sensor and the IR transmitter accompany with the Obniz. Can you let me know how IR transmitter works for different brands such as Panasonic, Carrier, Mitsubishi and etc? Is Obniz able to support the IR transmitter to talk to different brand of air-conditioners? If no, what should I need to do?

Thanks & Regard,
Marcos

Hi

Record and Play is the easiest way.
By using IR receiver with an obniz, You can record each IR signal of your remote controller.
No brand dependency. It format is binary array.
see

After that, Transmit a recorded binary data by using an IR LED.

A binary data you recorded is just an array of on/off. So it is not an output of analysis.

Or, if you already had a IR signal format. You can generate an array to be transmitted without recording.

Thank you
