If starting anew Thread is probably a better bet. Such as the Eve smart plug.

But with both zigbee/thread the problem is shifted towards the gateway instead so you'll have to do it yourself / pick one tu trust there. But here I think/hope Thread is going to have better interoperability.

With ZigBee at least there's dumb gateways that just plug into USB. I run one of those using a raspberry pi!
