When started, Blynk works OK and sends the values to the app, but after about 5 minutes, disconnects from the Blynk server and displays as stated on the topic title. I added a sleep command at the end and also opened and closed the Solar Charge Controller’s connection after every write statement, just to make sure that the data will not overwhelm the server. Any ideas?
