if so, does tt mean ur wifi needs to be on 24/7?
Your wifi is turned off at certain times of the day?
I suppose it could be possible if your protocol is not dependent on wifi signals bah?
ZigBee 3.0, z wave and Matter (over Thread routing) should be independent - they use radiowaves but not the 2.4ghz and 5ghz/6ghz protocols in wifi standards. ZigBee is 2.4ghz but handshake is totally different. Your IoT devices should still be able to communicate with each other and automations should still run.
You have a SmartThings Hub V3 ?
IHost Hub?
Tuya/MOES hub?
I don't think it is a straight forward binary answer since it depends on your use case and the devices you are running.
