I did a few tests with several nodeMCUs I purchased in different dates and... it doesn't work in some of them. Sound like a batch of them are faulty.
Definitely it is a hardware problem.

Thabks a lot for your message, it put me in the way to the solution.

Forgot to say, I flashed ESP_Easy_mega-20190928_normal_core_241_ESP8266_4M1M.bin to my ESP.

First of all, thanks for replying TD-er. I have a proximity (ultrasonic) sensor (RCW-1601) connected like this: Trigger to GPIO-12(D6) -> Set as Output High Echo to GPIO-13(D7) -> Set as Input The rest of pins are set as by default. Without DeepSleep it works great, giving measures every second. Do ...

Hi ESP friends, I am working with a ultrasonic sensor ('detector' device in code) to check when an object is close to it. I got a NodeMCU v3 (ESP 8266 12-E) and flashed into it. GPIO16 (D0) is connected to RST Set the wifi settings, MQTT... and the code, like this: On detector#Distance>0.0 do Publis...

Just found the way, the right code is:

Hi there, I am setting the behaviour for a magnetic sensor to check if a door is closed. GPIO04 is set as input. This is my code: on System#Boot do Monitor GPIO,4 endon on GPIO#4 do Publish,home/garage/maindoor,%eventvalue% endon on MQTT#Connected do Publish,home/garage/maindoor,[GPIO#4] endon MQTT#...
