Wrong. Not an I2C device, no address.There is a HX711_multi library out there that allows several devices to share the clock pin, so four common digital pins are needed for three devices.Leo..
Did you search for, read, and install a HX711_multi library.All the information should be on those pages. One clock, three data lines.The HX711 is digital.Nothing do do with analogue, apart that some examples use analogue pins as digital, to confuse you.Get ONE HX711 working before you expand to three.Search for which pins you can use on a WeMos. Not all can be used.Leo..
