    Some things that should help:

    1. Press ctrl/cmd+T in the Arduino IDE. That will auto-format the code which will make it much easier to spot mistakes.
    2. In the forum, code is marked with three backticks, not [code]. I know it's a bit non-intuitive but it is just the way the forum is. I took the liberty to changre your [code] to backticks to make the post to make it more readable.
    3. Comparing if a value is smaller is done by <= in c/c++. But it looks like you are trying to compare the value (which is always 0 or 1) to 15. That seems a bit strange. Adding a comment explaining what you are trying to do should help others (and perhaps yourself on day) to figure out what you ate trying to accomplish.
    4. The code to run inside an if clause should be surrounded by { and }
    5. The if clause and the two gw.send can probably be replaced by a single
      gw.send(msg.set(value==HIGH?1:0));


  • Sorry for the lack of clarity . I have used your tips to and update the sketch to no avail . What I am trying to do is use the switch to activate the time and use the time the switch was activated ( lastSwitchTime ) to compare to the (alarmTime ) and send the new (value ). ? . Once I resolve the current issues : I haven't gotten to it yet but , Once the alarmTime alarm is met I would like to have locked in requiring a reset are possible button push to clear it .
