I have completed most of my conversion from IRIS to smartthings.
I have two systems, one on my boat, and on at my home. For the boat I selected a standard current production smartthings hub. For my home I selected the ADT hub.
From a conversion standpoint moving compatible devices from IRIS to smartthings is easy. All you do is remove the device from IRIS, then reset the device per the manufacturer instructions, then add it to smartthings.
I have so far moved
The process is easy peasy.
Now… Some differences you will notice.
With smartthings there are two applications. I know it sounds silly, but right now you will need both applications. Just download them both and be done with it.
IRIS users will strongly prefer the new app, as it has a IRIS like look and feel. There are just a couple of things (like re-naming a device) that do not work in the new app yet.
For the “standard” (non ADT) hub you will need to use a automation called “smart home monitor”. In this automation you will be able to place sensors into the different alarm categories (Away, Stay) which are the same as “full” and “partial” in IRIS.
In the ADT hub you do not get this programability. Contact closure sensors are in the “stay” and motion sensors are added to these for the “away”. One thing I have not found how to do is to exclude a contact sensor from the alarming. This would be handy if you had a contact closure on your mailbox for example. I’ll be working on that later.
the old “rules” has been replaced by “automations” The REALLY cool thing here is that you can set more complex rules than in IRIS. You can have AND or OR functions. For example if A AND B AND C are true ten do X, or you can set up if A OR B OR C are true then do X. That is a Very powerful addition.
I’ll post more as I learn more, but my first impression as a IRIS user is whay did I not choose Smartthings in the first place.
