TASMOTA Smart Meter Interface with Easymeter Q3DA 1024 and WEMOS, some Information for a correct hardware setup

[DrMucki]

While doing a setup for Smart Meter Interface with Tasmota, you easily find this:
https://tasmota.github.io/docs/Smart-Meter-Interface/#easymeter-q3d-q3da1024-obis

There you can read something about, that Hardware Serial is needed. But it is not necessary in this case!
What you have to do when using a WEMOS is simply altering the user_config_override.h: like shown in the introduction.

A photodiode can be attached easily on the demos d1 mini between D4 and GND. An Additional pull up resistor with 4.7kOhm has to be added between D4 and 3.3V.

For the Q3DA 1024 the following script is working
