Can my smart meter tell me what my battery is doing?
No. Your meter can't see your battery. It can only see what your battery changes.
The meter sits where your house joins the street. It counts power coming in and power going out, every half hour. Your battery, your panels and everything else in the house are on the other side of it. The meter adds them all up into one flow. It never sees the parts.
What it does see is the result. A battery home buys less from the grid in the evening and sends less out in the middle of the day. Those two smaller numbers are the battery's fingerprint, and they are what your retailer bills you on.
Your battery app is the other half of the picture. It sees the battery, the panels and usually the house, because the inverter has its own measuring gear. It can tell you what the battery did today. It can't tell you what that was worth on your plan, and its "grid" figure won't always match the meter's to the decimal. The meter's figure is the one on your bill.
What to do
If you want to know whether your plan still suits your battery, use the meter's record. Ask your network or your retailer for your meter data file (NEM12). They have to give it to you, and most networks let you download it yourself with the meter number (NMI) from your bill. Our meter data guides show where.
To go deeper, read how your smart meter records what you use and make. It covers what the meter writes down, why one half hour can hold both an import and an export, and how your retailer turns the half hours into a bill.
