Solar Dashboard Project

[jonathan]

just noticed i now have totals! though probably not accurate it is something!
update: 5.1-00cd7d-2023-02-13-06-58

Yep! I still need to look into the totals and verify the numbers exactly, it's going to be done soon.

Here is how the latest update looks in snektek dashboard.
"Topograph" supposed to have anything? currently its blank.
Thanks Jonathan for the great updates!

Yes, I am looking to do something more graphic with the topograph view, for now it's a placeholder. I'm thinking showing the solar panels, battery, any load etc. I am open to ideas. You have some experience laying our your Graphana page, any comments on what I should do?

Hi Jonathan
Have you considered adding graph/numbers from connected Inverters? My system consist of ePever charger and Inverter both connected through a RS485 extender like on this drawing.

Currently I have replaced the MT75 with the Snektek module, so I have access to both ePever and Snektek clouds. But the Snektek module could adress both solar charger (ID=1) and Inverter (ID= 3) if Software could do that. The ePever cloud can not do that with one dongle but you must have separate dongles connected (one for Solar charger and one for Inverter).

Hi Fred thanks for sharing your setup. What kind of info does the inverter provide? I tried looking for a register list for the inverters but I can't easily find it.

For our purpose I think we will try to keep our products one to one, so each device has a Solar Dashboard attached, this way it becomes more maintainable and flexible without needing all kinds of adapters and wires.

I've confirmed the totals are accurate on epever, renogy, victron

Gosh not sure. I will think about that!

@jonathan my totals actually stopped working in HA. did anything change 6.0-9107c0-2023-02-28-19-21? PV Generated Today now shows Zero but in snektek dashboard it shows 1.417kwh and this was working just a few days ago.

Code: Select all

{"t":1999958289,"pv.v":1.3,"pv.c":0,"pv.p":0,"bt.v":13.2,"bt.s":100,"bt.c":0,"bt.t":21,"eq.t":22,"ld.c":0,"ld.p":0,"sn.l":4.294967e9,"sn.ah":4.294967e9,"sn.ap":4.294967e9,"sn.at":4.294967e9}

[randr]

that did indeed fix issue. Is this documented anywhere? maybe update the HA thread with new code?

@jonathan, I have noticed that temperature auto scaling does not function below Zero degrees Celsius. Not sure if it has always been so ,but certainly on my Version shown in attachments
