Hello, I am using NodeMCU 12E esp 8266, I connect to Wifi, messure temperature on GPIO 2, send it to database and than I go to sleep with this command ESP.deepSleep(1200e6). And power consumption is always around 77mA and datashet said that consumption should be around 20 mikro Ampers. Please help.
The board goes to deep sleep for 20 minutes and wakes up, no problem, but power consumption in deepSleep is problem. Here is the code:
