Ask HN: Is your home automation secure?

One reads a lot about home automation related (or IoT, for that matter) security incidents, yet there's at the same time a big market for these products. It doesn't look it is only for die-hard enthusiasts, seeing many beginner's guides obviously addressed to non-technical users. Statistics are misleading anyway - they list like 69% of US homes having at least one smart home device, although my home (not in the US) has every one of them carefully disabled. I'm really curious to know from somebody who "automated" their home, what are their thoughts about security? That it won't happen to them? That the drawbacks or possible losses are minimal? Or they put special measures in place to make sure it won't happen? Are certain brands more trustworthy or more upgradable than others? Thank you!
