Grafana Dashboard

[ezigold]

Awesome job Johan THANK YOU :)
I have finally found some code for growatt inverter data that actually works :)

I have used it and can now visualise my inverter data using grafana on my RPi4

[johanmeijer]

Thanks!

Look nice. I lost my grafana dashboard due to RPI chrash. Advise: don't forget to make a backup! RPI's (sd cards) are very brittle.

[Dandiiik]

Very very nice, should this setting be obtained?

Here I'll share my Grafana dash too. Happy to share the code - or something you can adapt to your data.

[Dandiiik]

Yours is very nice too. I can not do it. Can I ask you to share your settings?

[the-butterfry]

Why don't you start with @johanmeijer dashboard below. It will give you the items you need that grott supplies. My dashboard mostly includes data from my Bluetooth BMS (jbd / Overkill solar bms) and wouldn't be useful unless you were using that system too.

[johanmeijer]

I created a simple example dashboard (absolutely not that fancy as the ones above but nice for a start).

You can import this file to start with. You can find it here:

https://github.com/johanmeijer/grott/tree/master/examples/Grafana

My own dashboard looks a little bit different but there is also information of Energy Usage, Gas Usaga and my 20+ year old solar panels on it.

Thank you, your example helped me a lot in setting up my charts. But the outputs do not work quite well. I have 3x SPF5000E

[johanmeijer]

Ok interesting. You have 3x (3 different) SPF inverters? Do they have al separate datalogers (shinewifi/shinelan) or do hava a shinebox with RF dataloggers?

I do not a have a lot of experience with multiple inverters. In influx/grafana this should give 3 measurements with the different values? Do you see this?

The fields for a SPF are different. This should be the values you can select.

        "BatDischarVA"      
        "BatWatt"           

I tried to match this as much as possible with the growatt fields (website / documentation: https://docplayer.net/199800433-Growatt-offgrid-spf5000-modbus-rs485-rtu-protocol.html).

But the mapping might be not complete (I see by example I mis output DCV) but that can be correct if needed. Same values are copied in 2 fields (because of compatibility).

I am not sure which values you need (are interesting). I should go for (first try): pvpowerout (= same as op_watt), epvtoday (=pvenergytoday), epvtotal, pvgridvoltage (=outputvolt), line_freq). invtemp

But i do understand you also want to display battery information. I only do not know which fields are of interest (I do no have a spf/battery).

[Dandiiik]

Thanks for the quick response and help. Yes I have 3 inverters the same and 3x Shine Wifi S
I see the data, but when it shows it in graphs, the values ​​are different. Incorrect values ​​appear to be assigned. Or they look and they don't show up.
I want to try to run 3x Grott with different port. Or what else could I try?

[johanmeijer]

Maybe 3x grott might be a solution. I know grott works with one shinelink and multiple inverters connected with rf. 3 Separate dataloggers I have not tested yet (comming soon I have a second one bought) buf I have seen unexpected behaviour (see also issue #110).

In future I want to improve multi threading for Grott.
