    I think the main problem here is you resurrected a near six year old thread related to solving a particular problem to ask if you could do something else to solve an entirely different problem.

    It could work. You could also send a pulse, serial data, then the 1800Hz signal. Or just loop waiting for SERIN using qualifiers, no need for pulses or interrupts.

    Pairing the RF remote with the module in this case.

    But that did trigger a thought. Do the Sonoff modules need configuring for WiFi / server control before they will accept RF pairing ?

    You need to email support @ picaxe.com to request deletion.

    Alternatively you can email to request a change of username if that's what you are concerned about.

    A pulse is being output before the serial data is sent so that pulse can trigger an interrupt in the receiver which then executes SERIN to read that data.

    If PWM were put before the data sent the...

    Possibly not easily. The PICAXE dedicates itself to playing the note and that may disrupt the background servo pulse timing. You may be able to tweak the PAUSE time to reduce or avoid the jitter. Or...

    You are right; that's not needed for a genuinely open-collector output.

    In fact the diode solution turns a high/low, V+/0V, signal into what is effectively an open collector output which can be...

    I would recommend not directly interfacing with the black button. Because the module uses mains you run all sorts of serious risk doing that. Controlling via RF or WiFi would be the best way.

    Pin C.4 being Serial In is probably the cause of your main problem; in the simulator and real world the PICAXE will reset and the program will restart if a DISCONNECT command is not included.

    That is correct. It is a common condition known as "Phantom Powering" which applies to some extent to most microcontrollers.

    Via eBay or similar, or sold through your own web site, with a link to that would be the best way of doing it. That opens the least number of 'cans of worms' and would give you a greater audience.
