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?

Guido

Hi,  
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
