Thank you for replying!
For the purposes of trying to find the root cause of the incremental drift, I am not using the median of 35 samples but rather outputing every sample.
The graph was created from a txt file that I have let the script output to for the purposes of this analysis, this was then read using pandas and displayed using matplotlib and seaborn - I'm confident the graphing isn't the issue, I'm not performing any data manipulation.
I'm using a Sparkfun HX711 that has both the VCC and VDD connections:
I have connected the strain gauges following this diagram here. Please ignore the GPIO side from the HX711 as I'm using the connections in the original post based on the Sparkfun documentation:
I re-checked my outputs from the wheatstone bridge and swapped the E+ and E-, this is what it now looks like after running for a while to see if it would stabalize. The large spike around 1000mins is my test weight of 449g being added. What's throwing me is the odd random spikes, that seems like some form of disturbance beyond regular drift. No further along!
Weight vis across 1400mins looking for stabalization:
