Loved this list and just added those measuring spoons to my house's wish list. To the home automation front, for Home Assistant users I really like IKEA's line of zigbee controllers. With HA and a cheap dongle you can control any smart device with them, not just IKEA stuff.

• I have one of their speaker controllers hooked up to my partner's Google smart speakers, so I can turn down the volume and play/pause without shouting at the voice assistant.
• We have a five-button light controller on each of our nightstands so we can control our lamps and overhead lights (on/off, brightness, color) without getting out of bed. Great when my partner leaves their lamp on - I don't have to reach over them to turn it off. (Now if only I could turn off their TikTok stream when they fall asleep watching it...)
• Their $10-$12 light switches to control the lamps and overhead lights in all of our rooms. Tap once to turn everything on or off, double tap to turn on just the lamps for some gentler lighting.

And this isn't IKEA, but I need a colder bedroom to fall asleep, and my partner wakes up pretty early and wants it to be warm. I have a space heater connected to a smart outlet and a Bluetooth thermometer. At 4am it will start heating the room until we reach a comfortable temperature, idle until the temp drops, and turn itself completely off after I'm out of bed at 9am. If you need to buy the space heater or equipment to set up Home Assistant, this definitely breaks the $50 budget, but if you've already got those the thermometer and 15A rated smart plug will be maybe $30 total (cheaper if you can wait for longer shipping).
