I e be able to read data from the unit and possibly "press some buttons" from say a python program.
Maybe something like this can be done via bluetooth?

Depending on the precision you are looking for, you may be able to accomplish what you want with one of these hooked up to an Arduino with an SD card.
I've used the INA219 to log voltage, current, and burden voltage, worked great. Very easy to set up if you've done Arduino stuff before.

Or:
Since there is a way to transfer data over bluetooth, maybe I have no real.need for hacking either sw or hw...
newbrain:
The current FW is still 1.58 beta, and has been for a long time.
To this moment, it seems to be stable and probably the best one delivered.
It does indeed look less beta than other versions.
Is there any plan to make it "gold"?
Is a new FW in the working?
btspce:
I just bought the 121GW from Welectron here in Europe and it came with firmware 1.61 so the 1.58 is already "old"
Roelof:
Also, as has been mentioned before, the manual only has changelog information up to 1.51. Would it perhaps be possible to give us an update on the firmware status?
I do like my meter, but I'm very much looking forward to stable firmware with changelog information.
