I had installed openhab2 using manual installation. i followed the instruction like the link says
and I also had installed MQTT server clients, GPIO binding, and HabCloud.
I edited the items (Type in sudo nano /etc/openhab2/items/home.items) and I type :
Switch LED “LED” { gpio=“pin:21” }
I also edited the sitemap (type in sudo nano /etc/openhab2/sitemaps/home.sitemap) and I type :
Switch item=LED
I can open my openhab and turn on/off the switch on its interface. but nothing happened my LED.
Anyone can help me?
p.s : I use debian jessie OS, and GPIO pin 21 BCM
