For all your tech savvy guys, I’ve fixed some of the issues that you guys, and me, encountered (ip undefined, etc) and already fixed them on my own fork of the source code, see https://github.com/rkokkelk/com.jreenen.homeyharmonyhub/tree/develop. So you can use that repo to install the app without some of the aforementioned issues.
All fixes are submitted to @jreenen for them to be merged in the original app.
@jreenen feel free to delegate some fix issue work to me. It’s a great app, I love open source development and would gladly continue to make contributions.
