Hello everyone.

I am trying to automate my home and try to know the energy consumption that is occurring. For the I have:

- Raspberry with EasyIoT Server.
- NODEMCU-E12
- RS485 converter <-> RS232
- Power meter SDM230

I have been able to read the values of the energy meter to the NodeMcu with some problems.

My question is: Which driver would be best to forward all information to the raspberry?

The parameters to be transmitted are:

Line to neutral volts.
Current.
Active power.
Apparent power
Reactive power
Power factor
Phase angle.
Frequency
Import active energy
Import reactive energy
Total system power demand
Maximum current demand.
Total active energy
Total reactive energy

I would like to save them every second, can all values be transmitted at once? Or do they have to be transmitted one by one?

Thanks for your help and greetings

In my case, I am sending data via ESP8266. Data exchange window I set usually at every 10 minutes when line by line parameters from sensors are read (~10 ms delay each). That works cool few years.
