Hello, I have made the circuit attached. It is basically, a wattmeter with WiFi (ESP8266). It has been designed to be connected to an European plug (230VAC).
-This wattmeter can turn on/off the current flow.
-The ESP8266 will be programmed using a USB to TTL adapter.
-It has 2 ways of measure the current (using integrated ADC in ESP8266, or using an external ADC).
I need someone to verify the circuit has no errors.
Additionally, I need suggestions on how I can improve it to reduce costs.
Please, tell me how are you going to verify the circuit, and what are you going to deliver to me.
I want to be totally sure, that I can send this circuit to production and everything will work as expected.
