First off, welcome. If you haven't already been over to the Living With(out) Iris forum I suggest you pay a visit there as well. There's a lot of great discussions taking place over the various options that folks are considering.
The Iris 4-button fobs will work. Why anyone uses that garbage is beyond me. I broke two just changing batteries. But they are supported here. You can also use the buttonless SmartThings arrival sensors for presence. Those work well here too.
This might be possible. What exact devices are you using, or planning to use.
Not an issue. The Z-Wave ZCOMBOs are supported. As are Halos and some others that were approved for the "Works with Iris" program.
I recommend the NYCE tilt sensors. I've had 2 in an unheated garage for nearly 3 years. Still on the original batteries.
I'm not aware of any HA system that offers this, outside of Iris. That said, many options exist. I have a system similar to this in my RV.
Here's a great solution... It's not much bigger than a pack of cigarettes and provides roughly 12 hours of runtime.
There are definately some options here. It helps to know the specific devices you are considering. Check out the HubDunio project if you want to control relays.
That's not an issue either. Which ones are you using? The older Iris 1st gen devices will not work with Hubitat (or any other system for that matter).
The ability to run custom written apps and drivers, a maker API, a rules engine capable of making web calls, etc. Those are just a few of the options available to you. Hubitat is definately well-suited for the tinkerer crowd, yet works pretty well with a range of devices out of the box. This will help you get up and running quickly yet allow you to explore the more involved DIY opportunities at a later time.
Welcome to the forum!
