Welcome to the OpenRemote 3.0 platform; an intuitive user-friendly 100% open source IoT platform. We have our origins in Home Automation
but our 3.0 platform is focused on generic IoT applications and is a completely different stack to any of our 2.x services. As the code
base is 100% open source then the applications are limitless. Here's an architecture overview:

## Quickstart
You can quickly try the online demo with restricted access, login credentials are `smartcity:smartcity`:

This is usually caused by not running the stack on localhost
; if you are running the stack on a different host or port then you need to supply the EXTERNAL_URL
when starting the stack:

The error says Invalid parameter: redirect_uri for which you need to set EXTERNAL_URL . It would help if these both names are consistent IMHO, or even better the error should be something like Environment variable EXTERNAL_URL not set .

Hi Michal, Im new with Openremote. I’ve the manager running on “localhost” but when i like to make a IP command to the local host, i get the same “redirect_uri” How can you setup/change the EXTENAL URL? Can you help?

On Linux or MacOS you do:
export EXTERNAL_URL=https://YOUR_IP_OR_DNS_HERE
Please check the link which @Rich 's given above.
When running the External URL command with CMD the keycloack image gets stuck in a restart loop with the following fatal error:
08:59:51,252 FATAL [org.jboss.as.server] (main) WFLYSRV0239: Aborting with exit code 1

This seems a different problem. Please create a new thread and give all details of what you are doing and how it is falling.
