I'm enthusiastic about technology. I'm enthusiastic about HE. But I doubt, now, that Hubitat will take a larger slice of that pie. I think we "all" like to dig into the dirt, aka programming. It's a niche market like Radio-shack 40 years ago. We "assume" that everybody's ready to add some code to obtain more of HE. A lot of people are not skilled at all. They are plain stupid for stupid tasks like resetting a router. People are lazy, they don't want to read the doc (you know all RTFM, right ?) even most of the solutions are there, written.
We like add code, apps, sensors and triggers. Mr Lambda is probably not willing to install a wireless magnet to receive a warning when the mail is there. For sure, we like this.
Changing a light switch ? Officially in Canada, we need to call an electrician for that...
Young people then ? Except programmers, who want to write a rule ? And I don't speak about adding a custom app. I'm maybe an old tart but I doubt that people is ready to do that.
Even in regular conversation, most people can't stand basic logic... And you talk about writing a rule with If / Then / Else ?
I have kids (from 25-35), friends with kids, customer's kids and when I speak about home automation and the pleasure of it, I see no real interest (like doing home-automation). Ok, install a smart app on their phone, play with it a [add right time here] and install another.
To play with HE, you need enthusiasm and consistency. I don't count my hours reading forums, asking questions, reading pdf's and searching for tools. And when I see people around me, we are not common people.
I can be wrong, I would expect to be wrong but HE seems to me a niche market. I like it. Because it's my style and my whole house is a gigantic laboratory. Most of my friends have a house, but surely not like me. Sometimes a house with Alexa or Google in it. Most of them with a smart TV. Sometimes a Roomba. I think about this: how many people can really program their (super basic) thermostat ?
Just ask your neighbors about Zigbee... If they know how their router works (the buttons, not the architecture), you're lucky.
I'm not sarcastic, nor pessimistic. I just watch people around me. And I worked more than 10 years in IT with young people/customers around me.
