I like my smart light system for this. It’s all local too. The bulbs are connected by Zigbee, not WiFi. It’s a different kind of radio system specifically for this. That’s controlled by the Home Assistant software on my server. I wouldn’t ever recommend those typical WiFi bulbs that you don’t really control.

I put little Zigbee buttons on each nightstand. One press toggles the lamp there, double press toggles the overhead light. Long press turns off all the lights. Or I can use my phone. The lights automatically get dimmer and more yellow across the house as it gets later in the night. I can also use Home Assistant to control the fan by my bed.

Is it necessary? No. Is it nice to have? Absolutely.
