Two iPhone can't add Accessory Homebridge in one wifi network in the same time

My iphone can add accessory “homebridge” in homekit, and I can control the “yeelight” in homekit or siri.
But when I want to use another iphone to add accessory “homebrige”, it dosn’t worked. The ios app can’t find homebridge. All the devices are in one wifi network.

How could I solve the problem?

Hi, you could share the home you set up on the first iphone to the second. That’s how I do it.

Thank you so much. I have set it successfully.
