first, how much delay are we talking about?
second or millisecond?
depending on the distance and if the information passes by enough node it can have a slight delay
(like max 0.5 sec)
Zigbee-based lights should be combined into Zigbee groups in whatever Zigbee integration you are using instead of the Light Group integration. Doing so has the benefit of more in sync actions and reduced Zigbee traffic.
I probably got the same issue using the following setup:
HASS 12.3
Philips Hue Integration with 61 Philips hue devices
When I want to automate to turn on and off lights within a certain room based on a recognized motion-sensor motion, the lights turn on one after another, instead of simultaneously (which was the case when I was using the Hue App itself).
Since I don’t use a Hardware Zigbee Integration besides the Hue Hub, I don’t know how to resolve my problem.
Does anybody know how to help me here?
Here is the code I am using to figure out, how to configure it properly:
