We can use bridge widget for writing data to another blynk device but i think there is no method for reading data from another device.
here is my setup.
2 data screen for showing data ( its ili9341 screen on esp8266 and nextion with esp8266 )
13 sensor client (esp8266 with a couple sensors temp,pressure,moisture,leak,current, etc)
i can use bridge for writing virtual pins on ili9341 device. and working fine. but i plan to add another device for showing data on nextion display. i need to setup all modules again for sending to another device too.
and than if we had bridge read function i can read from ili9341 and thats it.
