There was a warning that if you have a POE switch the Hubitat is gonna burn out. But this says that active POE should not harm the non POE device. I was wondering can I connect the Hubitat to the ACTIVE POE or should I not?
Hubitat documentation has a prominent warning not to connect the Elevation hub to a PoE switch.

The documentation indicates that doing so can damage the hub and will void the warranty.
OTOH, you could use a PoE to microUSB splitter. There are several community members who have taken this approach.
Active PoE is fine. Passive PoE will fry it. I have mine directly attached to a Unifi Switch Pro 24 on a PoE enabled port with no issues.
I'm with @FriedCheese2006 . POE is fine as long as it's active. Mine runs on a Cisco 3750 48 port POE switch. I use splitters for all my hubs.
It can be done with the splitter, but the following states to not do so. I'd follow the Hubitat warning ... Hubitat
