I keep seeing people linking to that silly Josh.Ai thing. It's a whole lot of gravy with no meat or potatoes.
I've watched their videos, it was basically nothing more than what the "Rooms" tab of Hubitat provides, but with a bunch of giant obnoxious stock photos and a ton of "UI shine" added to it. Functionally it seemed significantly worse than Hubitat, tbh. Then the other part of this Josh thing is basically just Siri.
Is Josh very shiny? Yep. Is it good for selling to rich people with more money than sense? Yep. Would I ever want it in my house? Not unless it was about 95% cheaper than it is. It looks like a great product for integrators to sell, but it doesn't look like a great product overall. It's just a big expensive manual control interface.
Wall mounted tablets functionally provide nothing more than a regular wall switch does, and they lack any sort of tactile feedback or ability to be used without looking, making them worse than a regular switch. Voice control is handy sometimes, but that's easily had with Hubitat via HomeKit (or Alexa/Google if you don't mind having all your personal data gathered and sold).
I really don't see the appeal of Josh other than to integrators looking to add $20k to their bill for someone's McMansion home "automation" system. Automation in quotes since Josh seems very very manual control oriented.
If I'm spending big bucks on something, I'll put the fanciest presence sensors available in every room, 'passage' sensors on every doorway, lux/color temp sensors in every room, having my lighting always be the same brightness and color temp regardless of what's being added to the room from the windows, and never ever touching the light switches again. I'm definitely not putting some stock photo filled tablet on the wall that's in every way worse than a light switch from 1900.
