Good afternoon Everyone.
i have recently become a “blynker”. if someone wouldn’t mind helping me out a bit.
i am near the end of producing a working project to control 3 water pumps via reed switches to turn them on and off as i please. An issue that i’m having is the power meter i’m using (PZEM004T) does not relay information to my arduino board. I have been able to get it working over Software Serial to Blynk from the Arduino Uno via USB/ internet connection through the PC. My issue arises when i connected the arduino to Blynk via ESP8266-01 .My Esp8266 now connects the board Blynk through WiFi, but i have now spent a couple hours trying to get the PZEM004T to relay some information to blynk, or even the UNO itself.
