The SIMPL project has long maintained active hooks in its library to
Tcl/Tk. I've been involved with several projects where SIMPL enabled
Tcl/Tk modules were used with great success.
Recently a derivative project which makes use of SIMPL and those Tcl/Tk
hooks has started up to create a framework-plugin style application with
initial applicability to the building/home automation niche.
The opndrs project
https://sourceforge.net/projects/opndrs
welcomes Tcl/Tk and Python/Tk developers of all experience levels from
novice to experienced.
If you are interested feel free to peruse the information in the links and
contact the relevant mailing list.

PS
I'd love to see a completely Tcl version of this code created which could
be demo'd using the recently revived Tcl plugin.
