Is there a solid how to / walk through for setting one of those up? Lemmy world is flailing hard and I want to jump to my own instance.

I recommend you stay away from anything that requires any kind of portal to setup. If you have to download an app and create an account in order to pair the device or get it setup then don’t use that equipment. There’s a near endless array of sensors and things you can get now that work using Z-Wave, ZigBee, and even HomeKit that work DIRECTLY with HA, meaning that they don’t require commands to be sent up to the cloud via the Internet and then come back down to your device.

There’s an easy answer to that…don’t use IoT devices. I recently rebuilt my HA setup into a VM running on Proxmox, added a Zoos USB to ZWave dongle and then replaced every device that needed a network connection with a Z-Wave device. I have nothing left that needs, or can even connect to, the Internet and all of my routines / automations are fully local. I can turn my Router off and the only thing it will impact is remote access and voice control.
