Hello.
Before you buy the necessary parts, I will ask you to make it possible to connect the meter to your home router and send measurement data to the server to collect them there and draw a graph. I've already tested it and it works. Sending would be:
Voltage, current, power VA and COS fi and energy in kWh. And the fact that the kWh energy will be an incremental graph and it would be advisable to think about configuring the graph on the server to, for example, draw it in the form of a bar for each day.
Because it would be pointless to manually reset the meter once a day to reset the kWh counter

Sending data every 15 seconds because such requirements not more often. But it's enough for such needs.
