PJ-1103 clamp power meter (Improvement)

[tomassanjuann]

Information

Hello, first thanks for creating this integration, it works very reliable. This is my first issue created on GitHub and I don't know exactly if it will be better to do a pull request or other thing. I appreciate any advice. I've modified the device PJ-1103 to better understand and set the device functions.

Furthermore, I've modified the following parameters:

• Set the Voltage and Current as sensors and not diagnostic.
• Current as Amps vs mA. The energy clamp reads up to 3 decimals.
• Option to set the max effective and reactive power. In the Smart Life app, these values count in the percentage of maximum load it shows. Done the min/max range and scaling/step
• Minor name and icon changes.

First thread is #336. Also, the DP 17 which in theory measures kWh is broken, it resets every hour or so, it's like a counter. Currently using the Integration / Utility meter helpers and it works successfully.

[make-all]

• Set the Voltage and Current as sensors and not diagnostic.
  This seems like an unnecessary change. These values are effectively diagnostic values, as they are not really of primary interest for everyday use like the power reading is. Being marked as diagnostic does not make them inaccessible if you really want to use them, it just affects the default auto-generated UI.

• Current as Amps vs mA. The energy clamp reads up to 3 decimals.
  Again, this seems like an unnecessary change, especially now that HA supports unit conversion in the UI.

• Option to set the max effective and reactive power. In the Smart Life app, these values count in the percentage of maximum load it shows. Done the min/max range and scaling/step
  Thank you. It is also useful to get a definition of what the difference between these two is, as I think in the original info the names were in Chinese and both just translated to "max power".

• Minor name and icon changes.
  It is difficult to see what these are without more info

Okay, I didn't know about the unnecessary UI changes, my first issue sorry :) I think the commit is okay.

The minor name and icon changes were on the new items. I've named them Reactive Power and Effective Power, and assigned the mdi:flash-alert icon. That's also minor UI changes, so it's my personal taste.

The Effective Power is what the Tuya app shows as maximum allowed power, as a bar (see image attached). I really didn't discover what Reactive Power really do.
