The supernatural
smart bulbs in the bedroom. About 50-60$ per lightbulb, control them as a group, and no fighting with the spouse "you were the last one in bed, you need to go turn the lights off" vs "you're closer, you turn the light off"
Link them to your wiretap speaker of choice (google home or Alexa) and you can issue commands to it.
"Ok Google, turn off lights"
"Ok Google, set lights to 5%" (good for just a little light, getting ready to bed, not disturbing your spouse, or sexytimes)
You can get really crazy with something like HomeAssistant, but that's pretty technical in nature, but then you can control everything with your phone app, run automations to turn on the house lights when the garage door opens between 5:15 and 6:15pm (assumes you're just getting home). automatically lock the doors at 11pm, let you know when the trash hasn't been taken out, adjust lighting when the TV is turned on, etc etc etc.
