So when I go to MY HOME and look at SmartApps the app is not listed however when I go to Marketplace and look there its still listed.
If you don’t care about them coming on in unison, then just use Smart Lighting, here’s an example -
Four lights:
Home Office Can Light 1
Home Office Can Light 2
Home Office Can Light 3
Home Office Can Light 4
I want all to switch on together so I create a new entry in Smart Lighting -
Which lights do you want to control?:
Home Office Can Light 2
Home Office Can Light 3
Home Office Can Light 4
What do you want to do?:
Turn on & set level
Select trigger:
Switch
Which Switch?:
Home Office Can Light 1
Turn on lights when:
Turned On
Turn off as well:
Yes.
Then all you have to do is turn on ‘Home Office Can Light 1’ and all four will turn on (and off when it’s switched off again).
