After many years of using openhab from V1 thru to V3 I made the very hard decision to move to Home Assistant. I had tried HA a few times but found it quite a learning curve and stayed with OpenHab.
However after the upgrade to V3 I just found that each upgrade was getting more difficult to deal with as it kept breaking and I was reverting back to previous releases. (Note I was on stable release).
I did struggle to with the V3 interface for a while and never really spent time working out the dashboards (my own fault there). The frist straw that broke the back was the upgrade in Zwave that needed a few updates to allow various parameters to be returned to the correct values.
The final straw however was the last update the broke the node-red integration and required an upgrade to the new Open Hab 3 nodes (which also needed the latest version of Node Red - my bad on the issue there on not finding the issue I was out of date). It did however require me to update all my node red nodes for open hab and that was abit of bridge to far given most of my automations are in Node Red.
Then it came down could I learn anough about home assistant vs openhab and after it did take time as has a different approach. But once I learnt how it works with node red I was set and even now while I havd not coverted fully over I have use both.
I could chat about the communtiy and on that OpenHab wins as it is very friendly and I’ve been part of it for many years. I do wish all the community well and hope maybe Openhab V4 will resolve the lanissues on why I left. It is an amazing platform but does need some clear direction on the scripting. Maybe you will find the language to program in and go forward.
Please know all this is not a sledge against open hab. It has run my home for many years now, but i do think it needs to find itself again with regards to scripting and user interface. it just got to complex to work out.
