Hi Support Teams
I buy Sonoff products to sell in Viet Nam about 5 months ago
This time, I bought 30 pcs. I try to setup it but all is always offline. I try in iOS or android and different account, it still offline . I setup sonoff successfully many times before. I thinks error in hardware, service or sortware. I sent feedback in eWelink with email firstname.lastname@example.org.
Can you help me ?
Yes, I have this problem. How can I resolve?
