Unit WEIGHT issues

Hi, it's possible to attach at M5Stack FOUR Weight unit and read the weight for each unit?

Not sure as the documents are not clear.
I do believe there is an i2c and an I/O expander in the pipeline that may do what is needed.

Thanks @ajb2k3

As @ajb2k3 said, it's possible for you to realize this function with a IIC hub unit for avoiding IIC address conflict. We are developing this IIC hub unit. It will be put on sale recently.

I can control 4 weight attached at one core (fire)?

Yes that, sorry last check it was still in dev.

@watson one question, are you sure weight unit are I2C?
I see the back and report GPIO A/B/C...
I buy also this:

And I hope this works...

@yellowelise Really sorry about that. It's my fault. WEIGHT does not communicate with core through IIC.
