3EM get actiual power every second with minimal overhead ?

To get actual power of all 3 phases:

I am actually using "http://" + Shelly_IP + "/status"

or

"http://" + Shelly_IP + "/emeter/0" for each of the 3 emeter.

First method use massive overhead to get one simple signed value.

Second method needs 3 http requests. Is there a better way?

I want "http://" + Shelly_IP + "/aPower" and i want it every second. Is this possible?

So basically this forum does not only have a horrible layout with flashing ads but is also not useful?

Listen, dont let the ultratards from marketing destroy your brand.
