Read the SDM220 modbus with the minimalmodbus python module

Hi Ross,

The method of acquiring the data should still be good, but the method WRT ingesting it into
emonCMS may be different because of some small API changes.

Unfortunately, I stopped running emonCMS about the same time the post was made.
(I switched to InfluxDB and Grafana) So I’m not up to speed on the current version of emonCMS.

One thing I did do was to rewrite my Python script. I eleminated the sub-process call to the bash
script. Everything is handled by the Python script.

Suggest you start a new linked Thread, tell us what you have done and what you have tried to fix it.
I see you have.
