Deep sleep mode adding to code

Need Help With My Project
1

Hi, i’m total beginner and i need help. I’m creating this project http://www.instructables.com/id/Pot2/ but i need modify code, beacuse power compsumption is so high and i can’t add more 18650 to design and etc… Simply i want modify code, so NODEMCU will wake up every 30 minuts, read values, send them to Blynk app and go to sleep mode again. Can someone help me and modife the code for me please? BTW I already included wifimanager and probably going totally drop LED

I fixed your code formatting, as requested in the instructions you deleted in order to post this :wink:

We help you learn Blynk here, not troubleshoot or “fix” your code. :stuck_out_tongue:

Deep Sleep is not a Blynk related process… You can search this forum for some info, as others have used it with Blynk, but you might be better to also search the internet for ESP deepsleep related options.

Yeah i checked it but i dont know how to use it

More than 50 different threads on this forum when you search for “deep sleep”, many with code examples and detailed info on how to use deep sleep mode:

You’ve spend 26 minutes reading since you joined the forum. Spend a few hours reading some of these threads then come back with more specific questions and you’ll get much more help from the other forum members.
