Could you post a time series of your Growatt data (power and total energy), for let's say, 1 day, with 30s intervals? .csv or excel format will do nicely.
Just to test some ideas I have.

Hoeveel diskruimte heb je nog?

in en post de uitkomst even. Dikke kans dat die flash hartstikke vol zit.

Hi oepi-loepi, It's just a suggestion. The reason I posted this is because I'm just now using a PV S0 pulse simulator to test some meter adapters (and simpler wiring to connect PV inverters using S0 potential-free contacts to toon). After that, I need to couple my inverter to toon, with an extra har...

My previous post was a bit of a lecture (that's what I do for a living ;-) ). Got bored with all the skype/zoom/teams/bigblueblob stuff from today, so I took the liberty to add a bit of (pseudo) code to your arduino code. Each added section is commented with something along these lines: // add: .......

At the end of the day you want to get the total energy correct. That means that you should keep track of the amount of energy produced rather than the acute power. Maybe it's an idea to extract cumulative energy data, subtract the last number from the previous, calculate the average power in that pe...

Hmmm ... zon op toon data are sampled at 10s intervals. These data are then filtered through a moving average filter over 5 minutes (30 sample points). This gives the data as stored in toon (and as displayed) a delay of 150 seconds. At low power, time intervals between pulses can go up to tens of se...

... * This bridge will get the data from the GroWatt web interface (API) and create S0 pulses and led flashes * Each pulse/flash will suggest 1 Watt ... I guess you mean 1 pulse/Wh, leading to 1000 pulses/kWh, correct? Is it possible to increase this number? Right now I'm testing some solar stuff f...

Not a lot.
I once had one with a loose power connector inside, but that's about it.

Did you reset the meteradapter prior to coupling (push the small button on the side and hold until the LEDs flash, after ca 10 s)?

You are replying to a thread that has been quiet for the last 10 years. Not sure if all posters here are even alive anymore ...

That may be the case for a toon meteradapter, it would fry my raspi's GPIO circuitry. I think I'll keep them both in .

I happen to be playing around with a similar problem, and right now I am emulating S0 contacts with a raspberry pi. The replacement circuit for the optical sensors is fairly straightforward. The S0 contacts are typically open collector circuits. The meter adapter supplies 3.3V, so with a simple 1kOh...

You should be able to add them as attachment.

Goed zo! Viel achteraf wel mee, toch?

What toon is it (type 1 or 2)?

Kom op jongens, een beetje relaxter graag. Toen je voor het eerst een command shell onder je neus kreeg geduwd had je ook geen idee wat je ermee aan moest.
