Hi,  
I am a newbie, I use Photon to my project : Measure temperature and humidity and display in Mobile App.  
But I wonder how I connect to custom wifi with Photon.  
For example, when I change my wifi, i can send new ssid, password to my Photon to connect  
Anybody helps me  
Thanks!

Hold the setup button for four seconds until it starts blinking blue. Then add new credentials like you did before.

You could add [_SoftAP_](https://docs.particle.io/reference/firmware/photon/#complete-example) to your project.  
Or add a dedicated `Particle.function()` that takes your creds and stores them via [`WiFi.setCredentials()`](https://docs.particle.io/reference/firmware/photon/#setcredentials-)
