Using Blynk and Raspberry Pi to control an 8 port relay

Coding??

Just wanna check with you whether these relays are good for production use

I am planning for home automation

Hi, I need to control that relay board into my car, how can i use blynk without a router, just RB and my phone ? Thanks

When I start blynk. one of the relay turns on. Do you know how to solve that?

what raspberry pi are you using

my problem with blynk is it disconnect my raspberry pi from my cellphone after 3 hours !!!! do you have any solution to make the match between my raspberry pi and my cellphone forever ??
