[SOLVED] Amazon dash button: Steps for a complete setup

[binderth (Thomas Binder)]

@walterwampe

sudo getcap realpath /usr/bin/java

I do have a similar problem, as my dash buttons won’t initialize:

Amazon dash button: Things won't come online, INITIALIZING

After I upgraded to openHABian 1.3 and installed my amazon dash buttons, everything worked fine. After a few days, the dash buttons went into “INITIALIZING” and won’t come back online. If I restart the bundle in the oh2 console, it won’t change. [12:41:21] openhabian@openHABianPi:/etc/openhab2$ sudo getcap `realpath /usr/bin/java` /usr/lib/jvm/zulu-embedded-8-armhf/bin/java = cap_net_admin,cap_net_raw+eip cap_net_bind_service+ep is there a test for checking libcap is working?

It seems, my libpcap-dev is working also with the correct rights:

[15:03:45] openhabian@openHABianPi:~$ sudo getcap `realpath /usr/bin/java`
/usr/lib/jvm/zulu-embedded-8-armhf/bin/java = cap_net_admin,cap_net_raw+eip cap_net_bind_service+ep

I also get the error-message:
