Better macOS UPS support

[inventor7777]

Describe the feature

I downloaded the app on my Mac Studio and I was quite surprised to see that it found my UPS stats.

However, some of the stats are stuck in the Attributes, and are not displaying properly. I think these should be fixed and added to the main list of sensors.

For example, under Attributes, the UPS voltage shows as 117,000 volts. That…is a little high lol

TLDR Request

I think these basic UPS stats like voltage and power source should be automatically added as sensors (instead of just being attributes) and it would be a nice bonus if wattage was supported. However, I can’t find wattage even in Terminal, only in the PowerPanel app, so I’m not sure if that’s possible.

additionally, my Mac Studio comes up as an iPad, but this is outlined in #147433 already

Use cases

I have a USB-connected CyberPower EC850 UPS which doesn’t have any simple integrations, and this is the only simple way to monitor it.

Examples

I used a template helper (thanks, ChatGPT!) and created the sensors manually. So I think it should look something like this.

Anything else?

Using ChatGPT, I created some template sensors and I divided the value of the voltage by 1000, which works great. I just think this should be built in.
