the problem with home automation is there is no brand you can truly trust as they've almost all had some sort of unprotected flaw or have had their platform breached.
that said, if I do home automation, TPL's Kasa looks good.
Except I'm running commercial grade network equipment.
I have an Aruba 48 port switch, Unifi AC-Pro and a 1u box running OpnSense. Networked devices I don't trust get nothing more that internet access and have zero access to any other part of my network.
For other stuff I have Home Assistant setup and running a small ZHA based network with a few zigbee based devices.
