Yup, which is why I'm interested in privacy-oriented solutions like HomeAssistant. I think the main things I want are: - control temperature remotely (e.g. set furnace to turn on when I'm coming home from a trip) - turn on/off power outlets to save electricity from "vampire" devices - check for open doors/windows - adjust airflow to make sure rooms are heated sufficiently None of this requires sending data outside my home, yet the main smart home devices do. Also, I'm worried about security, and I don't trust these devices to update firmware appropriately. So, until I get time to do it myself, I just do without.
