I have some code that shows battery voltage status in the main window but I need someone with a suitable device to test it out.

To do so, first kill solaar. Then clone solaar from my repository, checkout the voltage branch, and run solaar from there via

git clone https://github.com/pfps/Solaar
cd Solaar
git checkout voltage
bin/solaar

The main window should show your battery voltage and provide a reasonable battery icon.
Reply with your experiences.

There is more that should be done, but I don't have the documentation for this feature.
@FFY00 Is there documentation for BATTERY_VOLTAGE somewhere?

Well, I think we have the permission from Logitech to use the battery curve, so I guess this should be possible.

FFY00 picture FFY00 on 24 Mar 2020

This requires implementing the BATTERY VOLTAGE feature so I'm changing this from a bug to an enhancement request.

pfps picture pfps on 11 Apr 2020

would this also support, G-Pro Wireless? or should I open a different thread with some of the solaar show output?

Right now my G-Pro wireless reports battery as unavailable

Thank you :)

mbinns picture mbinns on 10 May 2020

Yes.

FFY00 picture FFY00 on 10 May 2020

After recent update Solaar still doesn't show battery level of my G900, but also doesn't start automatically with OS.

Linux-Fan picture Linux-Fan on 24 May 2020

Battery voltage isn't implemented.

Diagnosing the startup problem will probably have to be done with whoever created the distribution for your Linux variant, but you should at least check to see that /etc/xdg/autostart/solaar.desktop exists and looks reasonable.

Hmm. Now that I look at it, it seems that sudo pip install solaar does not install the autostart file in the right place. That may be your problem, if you are installing that way.

pfps picture pfps on 25 May 2020

Yes, the PyPI package isn't installing the autostart and udev files correctly. There appears to be some very silly handling of data files that are supposed to go to absolute file names in binary distributions.

I updated Solaar on PyPI so that sudo pip install solaar does the right thing. Please check it out if that is how you installed Solaar.

It is implemented in the kernel, you can check the implementation there.

Here's also some documentation: https://patchwork.kernel.org/patch/11124945/#22872017

@pfps awesome job! Works and looks great.

@pfps I can confirm it works! Great job! Now, would it be implemented?

AAA

Linux-Fan picture Linux-Fan on 5 Jun 2020

@FFY00 That's useful.
The last missing bit, I think, is whether there are notifications for battery voltage changes and what they look like.

pfps picture pfps on 5 Jun 2020

OK, that part of the change worked, now for the next bit. :-)

What you have doesn't show the actual voltage. I added some code to show that (instead of "average"). The battery icon will still tell you that your battery is not full and not near empty (i.e., "average"). This is in keeping with batteries that report numeric values.

So please try it out again by cloning, etc., as above.

pfps picture pfps on 5 Jun 2020

The one remaining issue here is that your device probably emits a notification when its battery status changes and Solaar will not do anything with the notification. So if you keep Solaar running for a long time - long enough for your battery to drain - Solaar won't notice that the battery status has changed. If I get information on the form of the notification I can add that.

pfps picture pfps on 5 Jun 2020

@pfps New code doesn't seem to work in my case.
AAA

Linux-Fan picture Linux-Fan on 5 Jun 2020

OK, I'll try to see what is going wrong.

pfps picture pfps on 5 Jun 2020

Grr. I forgot to add a format specifier in one place (after I fixed it in another).

Please try again.

pfps picture pfps on 5 Jun 2020

@pfps Much better. Is it possible to get the percentage left?
AAA

Linux-Fan picture Linux-Fan on 5 Jun 2020

Getting the percentage left probably requires external information about the battery, as I don't think that the device itself reports that.
@FFY00 Is this information available somewhere?

pfps picture pfps on 5 Jun 2020

@pfps I'm not sure about other mice but G900 and G903 have identical batteries. They're 750mAh 3.7V or 2.775Wh. Based on that, we could get a percentage.

nick-s-b picture nick-s-b on 6 Jun 2020

Yes, but what is the relationship between voltage and percentage? It is not nearly linear, as far as I know.

pfps picture pfps on 6 Jun 2020

@pfps I wonder how Logitech does it... I'm guessing they have some kind of a LUT for voltages.
logi
I wonder if there are any open source drivers that already do this kind of thing...

nick-s-b picture nick-s-b on 6 Jun 2020

i mean there are also additional data points to it in the software (shown in the settings) so that's gotta be a factor too.

Dessa picture Dessa on 6 Jun 2020

It looks as if there is other information that can be obtained from the device, and other information about the device that could be used to compute percentages and time remaining, but obtaining and deciphering this information requires documentation about it. I took a look at what appears to be the relevant Liinux driver - https://github.com/torvalds/linux/blob/master/drivers/hid/hid-logitech-hidpp.c - but the only extra information there is that notifications look just like query results. So I expect that Logitech has some quite detailed voltage vs power level information and is estimating power consumption from them.

pfps picture pfps on 6 Jun 2020

I implemented battery voltage notification processing, but you will have to test the code by doing the four steps in one of my earlier comments - clone, cd, checkout, run.

Please leave it running as I'm not sure whether you will see changes in battery voltage or lots and lots of desktop notifications as the battery voltage changes.

Also, please run bin/solaar show and provide output, as I changed this code a little bit.

pfps picture pfps on 6 Jun 2020

There is some kind of error and it doesn't work.
