I’ve made two simple Blynk apps with two auth codes. How can I combine them into a single window?

I’ve made two simple Blynk apps with two auth codes. How can I combine them into a single window or App ?

AFAIK you can’t.

You can leave them as separate projects and use bridge / API to interface between the two.

Other than that you need to move one project, widget by widget, by hand.

I’m basically using a Gps tracker Blynk app and a Relay Blynk app with different auth codes on an esp8266 module, neo 6m gps module and 8 channel relay module
( not using all relays )

Just write down the pin and widget details from the smallest project and recreate on the bigger one.
