Set actionable notification dynamically

Hello,
I am trying the generate an automation, which should send a notification to my iphone, when a sensor != ‘success’. Furthermore I want to have a button which should trigger a switch in HA. I have 7 different thermostats and therefore I want to make the notification and button dynamically (should only get shown when sensor != 'success).

Attached you find my automation, where I have some issues. I believe my syntax of the for and if in the data of ‘Send Notification’, “Wait for Button Response” and “Perform the Selected Action” is wrong. Nevertheless, if i copy it in the development tools it seems to be ok?

Hope somebody can help me with it. (If I do not make it dynamically (so I always see all thermostats status and all buttons) I made it already work… (Y)
