Hang on folks.
First of all I wish all would get out of trying to put 3.236 out for the count. So far for me 3.236 is working correctly, all timers included. Plugged in 24/7 or not.
krpurcel, even when you turn the switch on and off in AHP and sometimes it works and sometime not, then issues like this all always contributed to signal suckers. I see issues like this even with 3.228 of which is still running at my business. With my XTB, WGL transceiver, and filters at home leaves me with no issues. My business does not have the XTB or WGL, but only a few filters and 95% of the time the system works while on a few incidents I will experience issues like yours or a timer missed a trigger off or on.
A signal meter will always confirm this for you.
Please feel free to list all module you have. Do a search for signal suckers too. Making a phase map of your home is always essential for any X10 setup. Unplug other items on the same circuit to help diagnose your problem.
Many here always welcome a challenge, but in doing so the last thing we need to do is make more work for ourselves before we use up all the easy options.
Good luck and never give up.
