Here is wiringpi addon: plugin.program.wiringPi-8.1.1-RPi2.arm.zip
It only has gpio program which I think it should be enough. With scripts from chewitt's post #3 it should work. If not you can send me one RPi2 and this button. And then I will write you detail intructions 
Files are in folder /storage/.kodi/userdata/addon_data/service.web.lamp.
/storage/.kodi/addons/virtual.dvb-tools/bin/dvbscan: line 6: syntax error: unexpected ")"
Seems you installed wrong addon version which is not for Wetek Play.
is that a bug or is the mysql server not open to the network? only localhost?
i have another LE box that i want to connect to the network and share the mysql.
I think others has one le box with mysqld for other boxes at home. But maybe they change something in mysql config.
I want to build 8.02 RPi2 (RPi3) with fix
LibreELEC-RPi2.arm-8.0.2-libcec-3953f8d-fixed-cec.img.gz
8.0.2 + libcec-3953f8d - it was fine on 8.0.1
Thank you very much. I will give it a try and compile it by myself.
Btw I think it is commit d1a708b (March 15th, third latest one currently) that fixes this problem.
I also thinks this commit is a fix.
Which build you need? I made 8.0.1 RPi2 and can build 8.0.2 also if this would simplify 
I'm running the USB-SD Creator on OSX and when I click the download button, it just opens my downloads folder.
And if you click Select Folder button nothing happens?
Make another package as dependency which doesn't build anything. It just unpack sources. And you can use them from original package.
anything dropped in the addons folder needs to be enabled
True. But this are system tools running from console only and doesn't interact with kodi.
wget http://addons.libreelec.tv/8.1/RPi2/arm/virtual.system-tools/virtual.system-tools-8.1.104.zip
unzip virtual.system-tools-8.1.104.zip -d /storage/.kodi/addons/
rm virtual.system-tools-8.1.104.zipand after reboot you will see commands available.
I think upgrade doesn't touch uEnv.txt in any way.
Ah, missed http link.
I think there is some solution to get at least checksums over https. But forgot how. Or maybe there isn't - other will help here.
qmake: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory
I get this too if type qmake on console. But still can make image.
You can get checksums like
http://releases.libreelec.tv/LibreELEC-RPi2.arm-8.0.2.img.gz?mirrorlistNo idea what this could be. I think it is cmake package problem because it should go to 100%. Seems you will have to figure out that yourself
