I’ve done a few really great ones. I got the UBolt Pro for a fancy lock I can track who accesses, auto lock, unlock remotely if needed, etc. It’s very handy for visitors because I assign their access code as the last 4 digits of their phone number so they never forget. I got Zigbee smart bulbs everywhere, but if I were to do it again, I would do smart switches in any places I didn’t need dimming or individual bulb control. Here’s another great idea: FANS. Ceiling fans, desk fans, whatever. You can connect good Vornado desk fans to a smart switch so you can get cooling on demand without getting out of bed. Lastly, an Aquasana under sink water filter. Only filter I know of that removes PFAS and PFOAs and is third party certified to do so. Good delicious safe water.
