sigrok-meter is a special-purpose GUI for libsigrok (written in Python 3, using PyGObject, GTK+3, and the libsigrok Python bindings) which supports certain classes of test & measurement devices that usually provide slowly-updating measurement values, such as multimeters (DMMs) or dataloggers.
It does specifically NOT support logic analyzers, oscilloscopes, and mixed-signal oscilloscopes (MSOs).
There have been no official tarball releases, yet.
Distro packagers should NOT package this, yet.
