Sensors plugin does not show battery voltage

In Ubuntu 18.04 LTS sensors plugin does not show battery voltage, however, in Fedora 31 there is battery voltage information.  I got suggestions about lm-sensors, and I did that, but on both Ubuntu and Fedora all ln-sensors does is show CPU temps. 

If I do this

upower -i /org/freedesktop/UPower/devices/battery_BAT0
  native-path:          BAT0
  vendor:               SONY
  model:                Li_Ion_4000mA
  serial:               0000
  power supply:         yes

    capacity:            63,0909%

    icon-name:          'battery-full-charging-symbolic'
  History (charge):
    1585481649    94,000    charging
  History (rate):
    1585481651    18,284    charging
    1585481649    24,052    charging


Proper information is shown, however, in sensors plugin under acpi there is no option for voltage available, in Ubuntu.  In Fredora there is section for voltage.

What gives?

Re: Sensors plugin does not show battery voltage

I can see it in Arch as well:
sensors.png

I looked through the Ubuntu 18.04 build log and it seems to build with all features except nvidia support enabled:

===============================================================
Build Configuration
===============================================================

The following sensor interfaces will be built into the plugin:
*  hddtemp: /usr/sbin/hddtemp (Make sure it is user-executable with UID bit set 
                      and user member of the respective group)
*  libsensors
*  /proc/acpi
*  /sys/class/power_supply

Support for libnotify will be built in.

Support for libnotify >= 0.7 will be built in.

Full debug is disabled

Do you have a "BAT0-0" sensors type?

Re: Sensors plugin does not show battery voltage

I don't have BAT0-0 sensor type.  But to be fair, I don't have that sensor type in Fedora 31 install either (I got another HDD so I can swap), but Fedora at least shows voltage, and Ubuntu does not. 

What can be done?

Re: Sensors plugin does not show battery voltage

You might try creating a bug report to see what the developer says. Since it works in Arch (for me anyways) perhaps creating a launchpad bug report for Ubuntu may be the best.

Re: Sensors plugin does not show battery voltage

I kind of solved it here.  I downloaded latest version from git and compiled it.  Now I do have the voltage from ACPI sensor type, still no BAT0.  Perhaps there are some options in ./configure that I have to enable to get BAT0??

I do remember that in Fedora 31 when everything was installed and updated, it also showed amps.  Anyway to get amps in there as well?

Is the value correct? Does it match up with the result from upower?

Can you post the output from your ./configure or ./autogen.sh command - especially the part at the end that displays the build configuration? They are enabled automatically if the supporting libraries exist.

Re: Sensors plugin does not show battery voltage

I tried playing with --enable-sysfsacpi and --enable-procacpi, nada.  Disabling both removes ACPI function from sensors plugin.  Funny thing is that typing sensors actually displays battery information and current.  That is from sysfsacpi since in procacpi there is no BAT0.  It used to only display coretemp, but now BAT0.  Now I wonder why there is no BAT0 in sensors plugin.

Re: Sensors plugin does not show battery voltage

Try building with "--enable-debug" and "--disable-xnvctrl" (it errors out if this component is built). Then run "xfce4-sensors" in a terminal and post back the DBG statements. There might be something in there. I can see:

DBG[acpi.c:262] get_battery_zone_value(): str_filename=/sys/class//power_supply/BAT0/energy_now

DBG[acpi.c:617] get_voltage_zone_value(): str_filename=/sys/class//power_supply/BAT0/voltage_now

... in mine.

I did update/compile from source lm-sensors and after I did that it started showing battery info when running sensors.  Now I see that perhaps the problem is acpi.c...  Problem is whenever I search for acpi on google I'm getting information that it is build in into Linux kernel.  Is that so?  Can't I get a dev version from github and compile it?

If not, perhaps I could configure kernel somehow? 

If not, perhaps modify sensors plugin to read certain values?

Re: Sensors plugin does not show battery voltage

DBG[acpi.c:463] get_battery_max_value(): str_pathtofile=/sys/class//power_supply/BAT0/energy_full

DBG[acpi.c:617] get_voltage_zone_value(): str_filename=/sys/class//power_supply/BAT0/voltage_now

Lets look at the code. When checking for energy_full, in acpi.c it does this:

#ifdef HAVE_SYSFS_ACPI
    str_filename = g_strdup_printf ("%s/%s/%s/%s", SYS_PATH, SYS_DIR_POWER, str_zone, SYS_FILE_ENERGY);
#else
    str_filename = g_strdup_printf ("%s/%s/%s/%s", ACPI_PATH, ACPI_DIR_BATTERY,
                                str_zone, ACPI_FILE_BATTERY_STATE);
#endif
    DBG("str_filename=%s\n", str_filename);

SYS_PATH and ACPI_PATH are defined in acpi.h:

#define ACPI_PATH               "/proc/acpi"
#define ACPI_DIR_THERMAL        "thermal_zone"
#define ACPI_DIR_BATTERY        "battery"
#define ACPI_DIR_FAN            "fan"
#define ACPI_FILE_THERMAL       "temperature"
#define ACPI_FILE_BATTERY_STATE "state"
#define ACPI_FILE_BATTERY_INFO  "info"
#define ACPI_FILE_FAN           "state"
#define ACPI_INFO               "info"

#define SYS_PATH "/sys/class/"
#define SYS_POWER_MODEL_NAME "model_name"
#define SYS_DIR_THERMAL "thermal"
#define SYS_FILE_THERMAL "temp"
#define SYS_DIR_POWER "power_supply"
#define SYS_FILE_ENERGY "energy_now"
#define SYS_FILE_ENERGY_MIN "alarm"
#define SYS_FILE_ENERGY_MAX "energy_full"
#define SYS_FILE_POWER "power_now"
#define SYS_FILE_VOLTAGE "voltage_now"
#define SYS_FILE_VOLTAGE_MIN "voltage_min_design"

In your images above, /sys/class/power_supply doesn't have an energy_now file. So is the debug output wrong? Do you have one in /proc/acpi?

Re: Sensors plugin does not show battery voltage

Okie doc, I did it, not a right way, but it works. 
lHFjEny.png

Firstly, I switched to my Fedora install on a trash HDD, and it did not show current right after install, I had to sudo dnf update and reboot, only then it showed current.

I dag into source and there is no class name CURRENT in acpi.c, so I assume current suppose to be taken from lmsensors.  And I do have my sensors command show BAT0 voltage and current, but xfce4-sensors is not picking it up for some reason.  Could be anything really, I have no clue.

I modified acpi.c and acpi.h and also language file ru.po (I have Russian locale) and sensors-interface-common.c.

In acpi.h SYS_FILE_ENERGY and SYS_FILE_POWER

#define SYS_PATH "/sys/class/"
#define SYS_POWER_MODEL_NAME "model_name"
#define SYS_DIR_THERMAL "thermal"
#define SYS_FILE_THERMAL "temp"
#define SYS_DIR_POWER "power_supply"
#define SYS_FILE_ENERGY "current_now" 
//"energy_now"
#define SYS_FILE_ENERGY_MIN "alarm"
#define SYS_FILE_ENERGY_MAX "energy_full"
#define SYS_FILE_POWER "current_now"
//"power_now"
#define SYS_FILE_VOLTAGE "voltage_now"
#define SYS_FILE_VOLTAGE_MIN "voltage_min_design"

in acpi.c line 671, that's just a label.  And changing last line in this snippet from POWER to CURRENT only shows proper labels but calculations are wrong.

                                                             ptr_dirent->d_name, _("Current"));
                    ptr_chipfeature->formatted_value = NULL;
                    ptr_chipfeature->raw_value = get_power_zone_value(ptr_dirent->d_name);
                    ptr_chipfeature->valid = TRUE;
                    ptr_chipfeature->min_value = 0.0;
                    ptr_chipfeature->max_value = 60.0; // a T440s charges with roughly 25 Watts
                    ptr_chipfeature->class = POWER;

In sensors-interface-common.c line 169

        case POWER:
               *dptr_str_formattedvalue = g_strdup_printf(_("%+.3f A"), val_sensorfeature);
               break;

And finally in my ru.po localization file line 338

#: ../lib/sensors-interface-common.c:170
#, c-format
msgid "%.3f W"
msgstr "%+.3f A"

It works, it's not a proper way to do it, but I like that it works, so who cares.

Re: Sensors plugin does not show battery voltage

Maybe create a bug report and post your changes so that it can be made to the official code as well.
