Uploading net meter to pvoutput to get consumption.

[rsilvers]

My home smartmeter meter is a net meter and so shows net usage. Can Pvoutput be configured to deal with that and combine it properly with my SolarEdge production to determine consumption?

I plan to use a software defined radio to read the RF transmissions from my GYR Focus meter and then upload CSV to pvoutput. Anyone else do this yet? The radio receiver is only $25 with the antenna and plugs into USB on a computer.

You can read your water meter also:

I did try a similar unit, https://www.amazon.com/gp/product/B00JQZU1ZO, to read a water meter remotely,
but the software was... unripe. Hope you have better luck!

I am going to use a Raspberry Pi. I don't expect the software to work without custom scripts. I will report back if I get it working.

New problem though - my utility meter is on 00000 and won't see to go to negative values. So that sort of throws a wrench in getting actual data, not to mention credit for my power production.

Good luck! I was running on a linux desktop, so the situation was similar. If you run into trouble wrangling the software, let me know, maybe I can help somehow.

You need to figure out how to access the non-visible internal counters instead. More info at your thread on that subject.

ERT only transmits one value so there is no way to see the internal counters. In fact, the POCO cannot see them either remotely.

But my meter did go below zero, so it will work out.

One can. One just has to wait for a Moderator to approve the post.

I am reading the meter from my Raspberry Pi now. It is working.

I'm impressed. Wonder if it would work on mine? Bruce Roe

Problem is, I am reading net. My meter is not transmitting consumption. So I am not sure how to get gross consumption into pvoutput.

[ButchDeal]

you will have to do the math to get consumption. PVoutput can help (you might have to make a donation). there will be some error as the two measurements are not taken at the same instant but should be pretty close.

I get gross generation from the inverters. My problem is getting net generation, which shows up once a month on the electric bill.
Then consumption is the difference, once you get the dates lined up.

Since the bill is delayed 3 to 4 weeks, its hard to plan usage approaching the annual reset date. Like, shall I heat the shed and
water with propane or electric? I may install a cheap but accurate, used revenue meter some day to keep a much closer running
account. Your distribution setup may be a bit complex to use that approach. Bruce Roe

You have an annual reset? I can carry a credit forever, and if I move, I can even transfer it to the new house (if the same POCO).

Cool. I just ordered the rtl-sdr to use with my Gyr Focus/RPi. What are the time intervals for the net readings from your meter? I'd like to integrate rtlamr output into my current python scripts that I'm using to monitor my inverter production.
