Hi, I would like to do the exact same project as I have two teenagers. How did you get on? Did you consider using a sound meter to listen for when shower is running?
Thanks,

I am Neal, testing a post to the forum

I am trying a similar project and with similar kit. I hooked my HX711 to my scale and Arduino and it worked perfectly first time, but when I tried the Raspberry pi / python it didn't show any data coming back. Please let me know if you have any luck. Are you using this for beekeeping?
