I'm sure I missed a couple - please let me know. This is just a start.

Do we want to include the LEAFScan? We've heard so little lately, that it's hard to guess whether it's still going to be released.

I don't think I'd include anything that is not currently available... Also, we might want to include next to each one in the fist entry, which buss(es) it monitors...

I would change #1 (or add in parentheses) to "Original Gid Meter"

Funny. :lol: I actually had that precisely (as stated, in parentheses) up to about 10 seconds before submitting and at the last minute decided to keep it uniform until I had some comments about the rest of the entries.

OK. Started filling in information and reordered in chronological order. I am not familiar with many of these so please correct any mistakes or omissions or suggestions for better pictures. Ran out of time this morning - will work on the others later.

Looks great, very informative about the various options available. Just a couple of nitpick suggestions:

1) Make the numbers the same font/size/color as each entry - looks odd when the number before each entry is in a small black font
2) The last few entries are not sized the same as the others

That's it. Excellent work!

The current firmware version of the SOC/GID-Meter displays:

%GIDs (of 281), GIDs, SOC, and
Pack Amps (out and in), Volts, and computes kW (out and in).

The logging feature captures almost all the CAN Messages
on the selected CAN bus, but misses some that are too
closely spaced.

A filter (not shown) makes the large LED characters readable
even in sunlight.

Yeah, I didn't like that photo, but I only had a few minutes this morning to hunt. If you can point me to a better one, I will update.
