I have set the following action and have no response from the light which is the subject of the action.
Action: FF 0 delay then 00 after 12 minutes
condition 1: (and) window 20:00 offset 3:00 (hopefully between 8 & 11 pm)
condition 2: (and) random time 28 minutes (hopefully between 8 & 8:28)
Thanks again for your help,
FOLLOWUP – I have set a light with similar actions and conditions as above and it is functioning.
