I am beyond impressed with the hardware, software and support!!
The first couple of weeks were not the easiest. I had a few battles trying to understand how the ZigBee and Z-wave were different from the ST hub. I also had some adjustments to make to RM after spending so much time getting use to WebCoRE.
Now that everything has settled down, I couldn't be happier. Not only do things just run, they do so faster and regardless of my Internet. I have 72 devices (13 are virtual) and 27 rules running them.
The Alexa and Lutron integration just work. There wasn't any thinking to be done. No added skills on the Amazon side for Alexa. No resetting all of my Caseta dimmers and switches to add them to Hubitat. Just a few clicks and a little info and they just worked. An added bonus was in being able to access my Lutron from both the Hubitat and ST at the same time. That made the transition almost seamless.
Being based on Groovy makes the the ability to add the device drivers from ST really great! It's not the most painless of processes and sometimes there is a bit of work to be done, but that was also the case with ST.
The support from both the community and the company has been spot on. There are a few things which will take time to sort out and the updates are coming at a reasonable pace. The fixes are targeted at making things work better rather than adding on bells and whistles which is really great!
When I bought it (I was number #17) I had the mindset that if it didn't work, the money lost wasn't bad. I am beyond surprised to say that this was the best home automation purchase I have made hands down. For the price it delivers HUGE and this is just at the 1.0 release. I am genuinely excited to see how this product and support mature over time.
This is a great product and I appreciate those who continue to put so much time into it. It has made my travels along the home automation path a lot easier.
