My guess is that this is some unwanted behaviour (you could call it a bug) within the Homey SDK. The Shelly App will not touch the the dim and/or white level when only the onoff capability is used. There is however a onoff.whitemode subcapability that will set the white to 0 when triggered. My guess is that the flowcard for turning off all zones also switches at least the onofff subcapabilities which is causing this behaviour for the white level. I cant really explain why it would also set the dim to 0 though. Anyway, as you already guessed yourself. This is not for me to fix but something Athom needs to look at. --- _[View the full topic](https://community.homey.app/t/app-shelly-smart-solutions-for-every-home-and-office/765)._
