I’m very sorry but i’ve switched my smarthome to ioBroker some month ago because of the very complicated DSL and Next Generation Rule Engine. ioBroker is an amazing system with Blockly and / or pure Javascript.
The migration of my 4500 lines of OH rules was done in 7 days.
FHEM -> OpenHAB: 6 month
OpenHAB -> ioBroker (90% Blockly): 7 days incl. bugfixing.
