Does this hardware exist?

Posting my 1-line for reference:
1-line-v3B.jpg
The way my system is wired, only 3 (soon to be 4) circuits are on battery backup. Just the usual critical lower-power stuff like the fridge. My heat pump, for example, goes down with the grid.

So when I look at the readings on my MATE3s (and OpticsRE) what I see for charger output is actually the sum of backed up loads + non-backed up + selling to the grid. I can subtract what is shown as "load" (my backed up circuits) from the total and that gives me the sum of non-backed up loads + selling to grid, no problem.

But to know how much I'm actually selling at any point in time I have to walk out to the electric service entrance and wait for my digital meter to cycle through its display until it shows "kW being sold". Not convenient given the meter location.

I know OB doesn't make this, but I'm wondering if anyone knows of a device that could be attached at the service entrance and transmit "power being sold" wirelessly to a remote display next to all the other OB hardware?

Gosh, if you'd seen my original.... It works for me.

There are 3rd party systems that would give you this info separately thru an app, and you could mount some sort of monitor showing the data near your OB equipment. This site shows a few: https://emporiaenergy.com/best-home-ene ... qgQAvD_BwE

Thanks Mike. I knew somebody had to making this equipment. And now I at least have a good search term to look around.

When you do, unless you want to scan a hand drawing, I highly recommend a vector drawing app. I used Corel Draw.

@Heimhenge

I like your neat diagram. What app or drawing software are you using?

The most redneck and awsome setup I have seen is the Wireless webcam pointing at the power meter to see what the meter says.

Amazon for like 50 bucks.

Had it displayed on PC next to his Mate3.

Lowtech and works well. :grin:
