    Hello

    I’m trying to control a radio socket outlet with my OSPi.

    I can switch it
    – on with ./433Utils/RPi_utils/send 1000 4 1 or ./433Utils/RPi_utils/codesend 1381649
    – off with ./433Utils/RPi_utils/send 1000 4 0 or ./433Utils/RPi_utils/codesend 1381652

    Can someone help me with the correct code transformation for the OSPi field “RF Code”? I tried several settings (DEC->HEX, etc., e.g. “1515111515140000”) without any success.

    Thanks a lot!
    Simon

    The code is 16-character HEX format. The first 6 are the HEX of the on code; the second 6 are the HEX of the off code; the last 4 are the HEX of the timing (in us). For example, your on code is 1381649, so the first 6 digits of the code would be 151511; similarly the next 6 digits would be 151514. You didn’t publish the timing so I don’t know what the last 4 digits would be.

    Thanks for your fast respond. I could now get some more information about the signal (please see below). Which value has to be transformed to HEX?
    An additional question: OSPi uses the GPIO 17 (Pin 11) to send the data, correct?

    Do not use the rest of the information if big coefficient of variation

    (This might be completely ignored, but pay attention to them if big differences are present and emission does not work)
    number of bits set (in 1381649): 8

    1076, 1184, 397, 486
    this might be useful for tweaking emmitting algorithms

    390 (pulse length) is the timing. So the last four digits should be 0186 (hex of 390). All together the code should be:
    1515111515140186
