[SOLVED] OpenHAB3 / Turn off all lights / How to use the semantic model to (easily) turn off all the lights?

Maybe this is useful?

Run rules for semantic groups in OH3

You can get all items from such a semantic tag. This is a part of a daily JS rule which checks for battery levels: var allBatteries = itemRegistry.getItemsByTag("Battery"); for (var i in allBatteries) { var state = allBatteries[i].getState(); ... Br, Stefan

Basically, you can grab all Items with a specific tag…
