Seconded. Lutron's devices connected via apple's homekit work well for us. No problems so far, the setup is pretty much set-and-forget and apple handles the security. You can disable access to the internet for lutron's bridge so no data leaves our home network.

Pretty good solution.

Agreed, Caseta are worth their price premium IMO.

The only downside is that they aren't available in the UK, but that's not uncommon for non-mainstream smart home products.

I'm sure you could find someone to reship product to you... And then you'd just need a stepdown transformer in your wall, and to import US spec everything else to go with it. Totally simple ;)

I think the best part about Lutron Caseta is that it still solves my problems without the internet connected hub. The internet connection only adds additional features, and nothing else breaks if that goes down.

Ex. I used a lutron caseta smart switch with and a pico remote to add three way switching for my kitchen and dining room. Where they used to only have one inconveniently located switch.
