Hello. Push notifications don’t work for China. We use google firebase service for push notifications and it is firewalled in China.

i guess so .:joy:
but i have VPN , my smartphone can get google.

Do you have widget in your project? Is project is active (run mode)?

yeah, all done!
but,the Wemos D1 maybe can’t get google, the VPN is only worked on my phone and laptop. i don’t know how to use VPN in the Wmos D1

You don’t need VPN for hardware in that case. As requires from hardware goes to Blynk server and from Blynk for firebase.

ok, thks for your reply.

one more thing.
i pulled a request on project https://github.com/blynkkk/android-texts , i translate it into Chinese, can you receive it? I hope the app would be change the language oneday, so that my student can use it easily in China.

last one.
I plan to write a book about IOT with Blynk in Chinese for teenagers,Can you give me authorization?
