Hi Folks,

This is pretty much targeted at UK people or anyone who has bought a
Wattson Energy monitor. (http://www.diykyoto.com/ )

While the kit is a lovely thing, the software that came with it is
rubbish. I've taken it upon myself to write my own software. So far, I
have a pretty good version working. It totally replaces the Holmes
software.

I am kind of stuck though on getting at the data in the Holmes
database. Has anyone done anything with it? Anyone else written their
own software?

This might not be the best group but.....

Cheers,
Crispin
p.s.
If anyone wants the software, feel free to give me a shout.

have you contacted them?  If yours is that much better maybe you can get
a little help developing and maybe sell it back to them?

I do some coding .. is this database part of their existing package?  
Maybe you could upload it somewhere and let us have a look at it.. might
known format you just have to figure out.

 Zachary,

I have but they are rather unhelpful. Someone hinted at it being
sqlite. I have not yet tried.
I would appreciate it if you could have a look. See if you can
download the file from:

As for selling it - I doubt it. It's a "I needed better software so I
will write it" thing. :)


Cheers,
Crispin

It won't load in sqlite v3

sqlite> .databases
Error: file is encrypted or is not a database

The first 48 bytes should contain the sqlite version and info, and your
file doesn't show that looking with a hex editor.  Or much else:

I thought it might be v2 but sadly:

[root@server1 data_test]# ./sqlite-2.8.17.bin data.db
Unable to open database "data.db": file is encrypted or is not a database

so it looks like if it is an sqlite database its probably encrypted --
probably decrypts within their application.  Have to dig into their
program maybe :)

I'll keep playing around some, but doesn't look good :(

Thanks for the attempts. Really appreciate it...
The app is free to download and install should you wish to try. I
believe it is adobe director. but may be very wrong...

Cheers,
