Autoconnection request for htop (hardware-observe)

Hi! The latest releases of htop (3.0.3+) added support for temperature sensors and battery status; but it doesn’t work out of the box due to confinement. Instead, it shows N/A with a warning message: Error: File /etc/sensors3.conf: Permission denied.

This is currently worked around by manually connecting hardware-observe.

Thus, I’d like to request the auto-connection of hardware-observe to make life easier for our users :slight_smile:
TIA

Is it possible to use system-files rather than the wide-ranging hardware-observe to get access to that one file? Does it work if you do?

No, it still needs read access to various entries under /sys/devices. Adding system-files with read: [/etc/sensors3.conf] and manually connecting still shows N/A in cpu temperature and battery status, with a pretty generic warning message Error: Permission denied, and lots of apparmor denials such as:

+1 to auto-connect hardware-observe. There was some talk of creating a hwmon-control interface that could have a companion observe interface, but it isn’t ready yet. At this time, IME hardware-observe is the correct path forward.

It’s been 7 days since this was requested. Do we need an extension for the voting period? Thanks!
