This open source home automation tool looks great! Unfortunately, I have installed several version of OpenHab and OpenHab2.
On both occasions I simply get a blank screen when I try to access the installed instance of Open Hab UI. Has anyone experience a blank screen when installing the DEMO version of openHab2? It is my understanding that this should be turnkey with no configurations required?
Since I am getting the same results ( Blank screen) on every install, I’m going to presume that it’s not a bug,
I have the following version of Java installed
version 8 Update65 / 32 AND 64BIT
Se development kit 8 update 65 / 32 AND 64BIT
I run OpenHAB2 from CloudBees and can always access the main screen after unpacking the runtime and addons zips and running start.sh. Just navigate to hostname:8080. No need to add openhab.app or anything. What OS are you running? Are you making sure all instances of OpenHAB are shutdown before running 2?
Thanks for the reply i will try this version from cloudbees ( https://openhab.ci.cloudbees.com/job/openHAB/). To answer your question i am running windows 10 ( upgrade from windows 7). I will post back.
Here are the errors i get when i try to run the openhab2 instance from cloudbees. I do understand that it had a communication error with com port 3. But other than that i am not sure, what is causing all of the java errors.
I would like to use this open source automation product as it offers a lot of flexibility, Any help appreciated at this point. when i point my chrome browser to http://localhost:8080 i get a blank screen with no errors.
if i access the url by IP address from a second Windows machine, i get a blank screen with no errors.
Thanks again for the help openHab community…
