Or if you want a simple & cheap off the shelf solution, IKEA stuff has being online as an option, not a requirement, and all the devices are ZigBee or matter compatible and not locked to some proprietary WiFi cloud bullshit.
Home Assistant! I got a cheap refurbished mini PC for 60 bucks and a zigbee stick for 12 or so, been running HA for a year now, it works very well and pairs perfectly with the IKEA zigbee stuff. I have it read the alarm from my phone and turn on radio on a wifi speaker and smart lights at that time. Kitchen light is now automatic with a little motion sensor and ESP I got from AliExpress for a few bucks. Everything is completely local, no internet access. It’s great!
