Trigger an automation when light is switched on

I use IKEA’s trådfri lights successfully in home assistant. To save electricity I always switch off the lights physically. I would now like Home assistant to trigger an automation when I switch on the lights (not via home assistant). The purpose is that I can check for daylight and turn on the appropriate scene.
Is that possible at all? To my understanding trådfri lights must report their status to home assistant and home assistant must react to that.
Thanks for any hint on that subject.

have you managed to find a solution? I am looking for something similar where automations should fire when I switch off the lights using the physical switch …

No, I haven’t, sorry.
