Hello, as the title says: if I try to turn my lights (IKEA bulbs) on via my Zigbee switches connected to an automation in Home Assistant, it can sometimes take half a second before the light finally turns on. If I bind them directly to my IKEA bulbs via binding in Zigbee2MQTT, the lights respond instantly. I know that logically binding them would be faster, but is it really that much of a difference?
#Zigbee via HA slow, but via binding fast

Do you use a USB 2.0 extension cable for your Zigbee dongle?

Do you use a USB 2.0 extension cable for your Zigbee dongle?
Yes, it's even a 2m cable now
The Zigbee dongle is located in my utility closet where I also have a router (with 4 antennas, the GL.iNet Flint 2), I don't know if that will cause much interference or be the culprit of the network being slow to react sometimes
I don't think it's my automation that takes a very long time to process

Do you have any issues with delay when you do a one-way command from home assistant to turn the lights on or off?

Just to confirm, not a USB 3 cable?
Some have trouble with wifi and Zigbee, I've never experienced it, even in an appartment with 50 SSIDs. But Wifi and Zigbee do share bands, there are charts to look that up.

I'm turning several lights on/off right now and they seem to react pretty fast, the automation I'm using is one that calculates which switch was pressed via MQTT, and then maps a light to that switch. It does take a good 100-200ms before the light turns on but sometimes it's just faster
And sometimes it even feels like a command is skipped and I'm forced to hit the light button twice

The 2m one is a USB 3.0 cable but I only started using that today, the first one was a 2.0 cable but that one gave me the same issues. I linked all my lights via binding in Zigbee2MQTT now and they are lightning fast but I lose the ability to do stuff with automations prior to the light being turned on

the other thing you can check is for any delay the other way - open up a view in ha that lets you see when it receives the switch event, and check if there's any delay between when you press the button and ha gets the event.
should help you narrow down which part of the system is most responsible for adding the delay. it's possible there's some unfortunate zigbee routing/interference issues between the switch and the HA dongle :/

USB 3 does interfer with Zigbee. Whole reason for the USB 2.0 cable is that you can position it away from any USB 3.

So what if I get a Raspberry Pi Zero 2W and stick the Zigbee coordinator into it, and place it in the middle of my house and then connect wirelessly to my network and use a USB over IP solution like VirtualHere to pass the coordinator to Home Assistant
Is that a viable solution or a horrendous option?
I don't have an ethernet cable to go into the RPi Zero in the middle of my house
