#88829 Hello. I have a problem with esp8266 NodeMcu v3. I connected the ds18b20 sensor with 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, after uploading the same code, connects to the router. Please help.
