iTach frequency

Configuration
1

I am beginning to test an iTach IR device with the home assistant. I still haven’t been able to get a simple On / Off command to work, but it maybe a hardware problem (still to be determined). While I have seen several examples; the part I struggle understanding is how the modulation frequency is set. In the example I see, the only thing that appears to be sent hex data.

This is the code from the components page not my code.

The IR data is in pronto hex format which encodes the frequency, a description of which is available here: http://www.hifi-remote.com/infrared/IR-PWM.shtml

Global Caché has a tool to convert back & forth between hex & their own text format called iConvert available here: https://www.globalcache.com/downloads/

You can try to look up your device here http://irdb.tk/ and see if you can just find the hex codes for the different functions.

Thank you. I stumbled across the hifi site a couple of days ago. Very informative!!

Hi,

My iTach gives me below type of code back (just in HEX)
How can I convert it to Pronto HEX?

sendir,1:1,1,37537,1,1,343,168,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,21,22,63,22,21,22,63,22,63,22,21,22,21,22,21,22,63,22,21,22,3700
