Driver Update 13/10/22:
I have removed the defaulting of the activity switches to ‘off’ as this was causing problems for users who trigger automations based upon the status of activities, as they were defaulting back to ‘off’ for 1 minute everytime the driver re-initialised itself.
This does mean when you add new activity devices, their status will be neither ‘on’ or ‘off’ until their true status is returned from the harmony hub which should take no longer than 60s. Unfortunately the smartthings app UI cannot handle a switch being neither ‘on’ or ‘off’, so will display an error instead of the switch status for the first minute after it is added.
I think this is a price worth paying for more accurate activity status.
The driver will update automatically, you can force it through the app or cli if you want it now.
@wags1 @TheHundredthIdiot thanks for providing input into understanding what was going on here.
