Probably over a year ago i built a rasperry pi and made a custom build of
openwrt and added a small patch for myself to make module for htu21 temp and
humidity sensor available.
the patch i made i'm not sure if it is correct or not and even if it still
works with all the changes that has been done but it would be nice to have the
kernel module (kmod-iio-htu21) built and available as an option preferably in
some future release.
i use the htu21 kernel module with a small shell script to push the data out to
an mqtt server for further handling.
there is probably more iio modules that could be useful to others but for now
i'm happy if i can make a new version of openwrt with the kernel module added
and preferably also get it included so i don't need a custom build.
below is my old patch.
