I switched over from SmartThings in July, for the same reason LAG. There have been some ups and downs, but I have been loving it. I am still rocking both hubs. I have the SmartThings ADT hub which I am using for my home security. What’s really cool about Hubitat is there is a built in app called Hub Link. This allows you to connect your SmartThings hub to Hubitat and have all of your SmartThings devices in Hubitat so that you can use them for automations. This makes for an much easier migration, or in my case allows me to still use my ADT sensors in Hubitat.
The only thing I have not figured out yet is how to use scenes with my Inovelli switches, but I’ll have to sit down one day to figure that out. I just ordered one of the new Red Series On/Off switch, so will figure that out when it arrives! Super Excided.
