if u send bch to the address provided; the lightbulb???? graphic will change color. (Not instantaneous, prbly need to add another script for that but there’s a refresh button)
Basically just reads the transaction count at the address and changes light accordingly.
I guess u can get more complex e.g. send with op_return hex color , and it will change to that, or something else?
:P anyway thanks for reading :) bch ftw!
*if you try please don't send alot of money, a few cents will do..
