ESP8266 Community Forum

Hello. I have a problem with esp8266 NodeMcu v3. I connected the ds18b20 sensor to the temperature preview in the Blynk application. ESP does not connect to Wi-Fi on my router. When I do hotspot from my phone everything works, there is a connection to Blynk. Another ESP, the same model, connects to the router after uploading the same code. I need it asap because i need to use my employee monitoring software for work!
