I’m trying to use a sparkfun qwiic quad relay daisy chained to a SparkFun Qwiic scale and the R4 WiFi cannot find the address for the quad relay. I am using the Adafruit 2.8” TFT LCD shield w/ cap screen.
I am using wire1 and the scale is identifiable, bit the quad does not work. I can get the screen working with touch. I have tried changing addresses, bit now luck. Of course I am new to this setup, so any help would be appreciated.

What address does the R4 want? What address is the relay?
Read the link @xfpd gave you it will tell you the addresses.
