i am trying to make a off grid system but I can’t do it. I have a esp8266 12e nodemcu.
parts.
- 8 channel relay
- ACS712 20 amp.
i have made this code for the relay and it works.

and this is the code for the amp meter
int adc = analogRead(A0);
float voltage = adc*5/1023.0;
float current = (voltage-2.5)/0.100;
float watt = 12*current;
can somebody help me make this come true.
i want to have the 8 relay on the web and to gauge to se how many amps and watts I use now and how many I have use over time.
like this
best regards Sophus Andreassen.
