Pomodoro & a Lamp?

Hey all,

Rather than trying to re-invent the wheel, I wonder if someone has already done something similar.

:exclamation:My issue :exclamation:
I work from home and have a wife and daughter that have a ‘habit’ of interrupting me.

My office is in our study which isn’t in it’s own room (so no door).

I use Pomodoro timers for my focus sessions.

What I was hoping to achieve was a smart light / lamp that changes colour when I am in a Pomodoro session or not. Then my family knows, ‘red’ for example, means don’t interrupt.

Totally open to any ideas!
