Issue on 868Mhz sunny beams ?

[alandpearson]

Hi there,
I have inherited a sunny beam that works on 868Mhz.
The display is blank, and it appears someone has been inside it and broken the ribbon cable to the display, so it's hard to know if it is working or not.
However, it is detected by linux on USB and running SunnyBeamTool gets the following output 👍

Sunny Beam not accessible. Run this program as root.

This was done when the inverter was sleeping, and I'm not sure of a few things

1. Does this work on non-BT sunny beams ?
2. Is this expected output when inverter asleep ?
3. Or, do you think the my sunny beam is.. well, broken ?
4. Is there a way to read the data over RF (e.g. using a jee node, RFM69 module, arduino etc) that doesn't involve sunny beam for non-BT versions ?
5. i assume my SB is not BT as it does not have the BT logo on the case anywhere ? (Confirmed by looking at pictures in the documentation for both models, this is a 868mhz unit)

Any clues or help appreciated....

having the same issue, working on the code a bit to modify it for my usecase. anyone having any luck?

In my case, the sunny beam itself was faulty.. proven by the windows software not able to read from it either. In the end, I installed a RS485 card in the inverter and used https://github.com/pkwagner/yasdi2mqtt to do what I needed. There are definitely 2 versions on the Sunnybeam, older non-BT ones and the BT ones. Alan

mine is the non BT one but I don't think it is faulty as I have a perl script that does work it is just the C variant that doesn't, so I,m actually trying to cross reference them to see if I find the solution in the perl script to make the C code work.

This is a very old project, originally written by Michaël Peeters
I made a copy here on Github once, because it is related to my SBFspot project.
There were already similar issues almost 15y ago, so I can only wish you good luck finding a solution.
