esp8266 and esp32 boards from ali plus various parts. Flashed with tasmota or (for the glow electricity meter reader esphome). Temp & humidity sensors, somfy blind controllers, ws2812 strips, relay to infra-red to control hifi receivers. Athom plugs pre-flashed with tasmota to measure power point usage and switch on and off. Athom bulbs pre-flashed with tasmota. Homeassistant works great. Toss in wireguard for remote access with smartphones. It's good fun. It's cheap. It's cloudless. It's better than anything you can buy. Go the DIY! You do tinker a bit, if you hate that aspect of DIY then maybe pass on smarthome stuff. Parts probably paid for themselves in reduced electricity consumption. Once you measure something, behaviour changes etc. I run Homeassitant on a 12 y.o. laptop that also runs mosquitto, has some usb disks plugged into it, runs samba, pi-hole, owntone, wireguard, timecapsule etc. Home assistatant works pretty well and easily, imho. How are you doing it?
