Problem solved Turned out to be a bad sensor and with mfalkvidd 's suggestion troubleshooting was a lot easier . Thanks

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 .

How do you move a post from a category to another category to avoid cross posting ?

That fixed the issue. It works great. To further enhance the sketch I added an alarm ,however I get an error as shown . Is there a way ; once the sent value of the alarm is set high that it is not changed based on future reading . requiring an acknowledgement or reset .

BartE I hope this isn't a test because I just failed . I get the following error when compiling .

I am trying to use the Binary switch example to monitor the state of a Switch .I want to be able to measure the length of time the switch is not in its normal state e.g.. "how long was the door/window open" I have found numerous timer sketch's but they seem to be for timing when something should happen . Anyone have suggestions or example sketch's

@tripy Thanks ; Tripy your solution solve the problem and pointed me in new info . I am slowly learning the solutions are available here .

he error that I get is

Can some help with this sketch I can't seem to figure it out. I will be so happy when I get past this newbie stage.
