Hello,

Does anyone have an idea how I can implement a switch-off warning (flashing twice) for my hall light?

I hope someone can help me with this.

Welcome to the forum!

How are you controlling your hall light?

Not directly an answer to your question, but easier to implement. Common way for switch-off warning is to dim the light for a given period before turning it off.
