For smarthome, I would recommend Zigbee devices. That way, you limit your attack surface to just your Zigbee gateway, rather than every single light bulb in your house, with the added benefit that those don't clog up your Wi-Fi.

We have the Philips Hue gateway at home (which has limited support for other brands, but IKEA Trådfri bulbs work), but you can also get a Zigbee USB stick/Raspberry Pi HAT, install Home Assistant or deCONZ, and go wild without being tied to any vendor.
