Sidehistorik

openHAB is an alternative to Home Assistant, and somewhat easier to configure. Where Home Assistant is Python/Yaml based, openHAB is Java.

Both systems has great capabilities, and differs a lot in the approach, but I do prefer openHAB and the UI is better and the UI configuration great.

One of the parameters for choosing, can be the amount or specific support for devices, its seems to me that Home Assistant has quite a lot more that openHAB, but also that several of them lacks functionality and are difficult to actually configure/use; I never understood the "media_player" stuff in Home Assistant. Visit the Showcase and How-tos site.

OpenHAB 2 supports the new Eclipse SmartHome APIs for bindings, and additional bindings can be found at GitHub

For the HAPanel in OpenHAB, theres a wide varity of widgets

During another problem/trouble shooting I ran:

sudo systemctl stop openhab2
sudo openhab-cli clean-cache
sudo systemctl start openhab2

That seems to remove stuff ... but a reinstall of the bindings fixed it (and no Things was lost)
