As promised in the post before, here´s the Sketch...and a question:
Question:
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!
