Fusion 2 Channel STR, Turn Banks On and Off Through I2C

I am currently working with the Fusion 2 Channel Board, WiPy2 Module, and the I2C shield breakout board. Normally I would use the NCD WiFi module on the main board, but those spots are filled and working. So turning to I2C seemed like the right move. I am simply trying to turn all banks on and off by sending commands over WiFi. What would be the best way to do this task? Is this setup capable of doing what I need?

Any guidance would be greatly appreciated.
Thank you.

Products use:
Fusion Board(https://store.ncd.io/product/fusion-2-channel-solid-state-relay-controller-with-16-gpio-or-adc-and-i2c/)
I2C Shield (https://store.ncd.io/product/i2c-shield-for-wipy2-lopy-with-usb-programming-port/)

Fusion provides a I2C master port (it generates I2C signals), it does not allow control from the I2C port (it does not accept I2C signals). Please let us know if you have more questions.

Thank you for the clarification. On a similar topic, is there any way to add a 3rd way, currently have Key fob (KFX Module) and the Xbee Pro S3B working on the fusion board. Could I use GPIO or UXP Expansions? Or do these also work like I2C?

Again thank you for the help.

GPIO and KFX both can be used to control relays, but KFX requires one of the communication ports. GPIO and UXP expansions may be your best bet.
