I’ve got it set up on Home Assistant so that whenever certain devices in my home are detected on or off via watt usage minimum changes I monitor on those smart switches, it toggles the Lutron Caseta (best smart light control there is) lights via commands for different rooms in my house.

I also have things like waterproof outdoor gate sensors made by Zooz that are smaller than a single stick of gum where the small flat watch battery in it lasts for almost a year and it will alert me when the gate opens or closes, but only when I’m a certain distance away from the house’s geofence I’ve set up.

You will also need an overall little USB stick to connect to your Home Assistant server device (like a NAS or Raspberry Pi) to control everything, but there’s one that’s made by Aeotec that does both Zigbee and Z-wave long range protocols. Z-Wave LR (long range) works really far too… like I think around a mile potentially, if you have a nice clear line of sight signal.
