For couch gaming, the discontinued Steam Link hardware is still king IMHO. I tried switching to the Android app on my smart TV and have had nothing but trouble with connection quality (even over a gigabit wired connection) and maintaining 4 controllers connected to the TV at once. It seems extremely sensitive to host hardware and software issues, which often change underneath you with TV updates. The Android hardware and software it runs on is just too variable to ensure a consistent reliable experience, and Bluetooth controller support is often hit or miss.
The Steam Link hardware was amazing as it did exactly what it needed to do, and most importantly was tested more thoroughly than the thousands of Android devices that all have their own quirks and specs. I hope they bring it back.
Just to play devil's advocate, why do you want to automate your lighting? I'd consider myself an advanced HA user (been using it since 2019 and have coded several custom integrations and built custom hardware) and never bothered with automating my home lighting. I'm always walking past the light switch as I enter or exit a room anyway, so it's not a big inconvenience.
The real wins I've gotten from HA are smarter home security (door locks/sensors/cameras etc), climate control, energy management, garden irrigation, and remote control of "dumb" devices like my garage door and motorised front gate.
Edit: thanks for the insights all! Seems having kids and older houses are common reasons for automating lighting.
