Survey via Actionnable notification

Hello HA community,

I would like to set up a kind of survey for my wife who suffers from joint pain when atmospheric pressure is changing (before storm for example). Actually I would like to confirm or refute this correlation.

To do so, I have already set up an actionnable notification based on pressure trend with 4 action buttons (From “No pain” to “Unbearable”).

My problem is that I do not see how to handle the answer (via iOS.notification_action_fired) in order to make an “answer graph” merged with the pressure graph.

Could anyone give me a clue to go forward?

Regards,

JM
