RoomMe works with IFTTT (v2.1 an up of the RoomMe app) and enables you to create IFTTT applets that trigger based on who's in a room and the time of presence.
When working with IFTTT, RoomMe based automations are created by creating IFTTT Applets with RoomMe as a trigger. There is no need to create charms in the RoomMe app. To enable RoomMe to work with IFTTT: In the RoomMe app:
Go to Settings -> Options and switch on "Enable cloud services". If prompted, sign in or sign-up to RoomMe with the admin email you've entered when you have set-up RoomMe.
On IFTTT:
Create a new applet.
Click on the "+" sign after IF.
Select RoomMe from the list of services.
Login to RoomMe with your RoomMe credentials. Note: if you do not have RoomMe credentials yet, select the Sign-up option at the authentication window and create a RoomMe user. You must use the same email address as the admin email address you have used when you have setup RoomMe.
Select the RoomMe user that triggers the applet.
Select which room the user needs to enter to trigger the applet.
Select on which days the applet runs.
Select the start time for the applet and the duration (how long from start time the applet is active).
Click the "+" sign after THEN and select the service and action that RoomMe will trigger.
Save the Applet.
