Re: Automation Not Working from Apple Home Pod : Why is Automation not working ?
We can not tell why automation is not working from your post us,
There are various possible reasons, and we don't have much info. to go on.
Eg: We don't know which hardware models and software versions are involved.
or if your lights are compatible.
