I still don't understand why you don't use deepsleep.
Lowest energy consumption, maximum life on LiIon cell....

Just fried my first ESP-01 while trying this. I don´t think, my equipment and "soldering skill" is yet good enough to realize that.

So, i still would be glad if anyone could help me, to fix my sketch so it makes use of light sleep (what it apparently does not).

Thanks in forward!

For my unterstanding, sleepNow(180) would mean an delay of 3 Minutes. In fact, 180000 actually is about 4 Minutes? At least that´s the time Thingspeak receives an update from DHT/ESP.

What to do to get an Delay of 15 Min. or more? With higher MILI-Values the script stops working.

Thanks!

PS: Script running...will see how long it lasts

You actually enter milliseconds, orrigionally you should enter microseconds, the *1000 just converts it to milli seconds, so 180000 milliseconds it what you enter right now.
For a bigger delay you have to just do multiple sleeps in series, there is something about the watchdogtimer that overflows, i think there is a way to disable that.

Kind Regards,

Yes i can help you , Yes you can send me a PM with a question - No i won't make the code for you

Tried

Code: Select allsleepNow(120000);
delay(100);
sleepNow(120000);
delay(100);
sleepNow(120000);
delay(100);


and

Code: Select allsleepNow(120000);
sleepNow(120000);
sleepNow(120000);


Neither worked. Maybe any more hints on this Watchdog-Thing?

Thanks in forward

So try a serial.println(mili) in sleepNow to see how long the sleep will actually be.
