Sensor stopped sending data

My sensor stopped sending data, the network environment is not changed.
I have unplugged the inverter, no result.
I have tested the inverter, works.
The power outlet is OK

Any suggestions?


Welcome on board.
What is an inverter ?
Can you read the USB log of the sensor ? You can use the monitor of the Arduino IDE.
Can you see the Sensor as an Access Point ?

Is the sensor in AP mode?

I use discovery tab for detecting sensors

If no sensor visible.
Connect sensor(NodeMCU) on a USB port PC/Laptop (windows)
Restart Flasher tool

Board is connected to …(this case COM3)
Download Putty (Free)

Open (Button) the terminal

Press Reset (RST) button on NodeMCU
