IKEAs zigbee devices are cheap, realiable and accessible and works great with Home Assistant + the deCONZ usb dongle. No WiFi connected devices, not internet access. When I'm out of the house I "phone home" with a VPN to adjust the temperature and turn off the lights if I forgot. I have automated several basic things, like the color temperature of the lights and the temperature of my heaters when electricity prices spikes. Unfortunately this is not really accessible for regular consumers, only for nerds who know their way around a terminal and vi(m).
