Thanks Robert. I will use that. There is a reason I want to do it in script although it’s hard to explain and my issue may be a symptom of something else I’m doing wrong.
And I get it now, must be my age. I was looking (expecting) the Run Script cards to be together so I was trying to work out how you could Run Script with Arguments. Then I found it, right down the bottom. And using this method I will need to use this method to set the Yes/No variable.
await Homey.logic.updateVariable({id:'5d153b3f-fb7d-45f0-9040-a34e5cc062ab', variable: {value: preserveState}})
Thanks again for your help. I was getting very confused.
