@freemo indeed, wouldn't help as direct feedback for adjusting daily dosage or something like that.
I recall my friend had a WiFi connected scales from Xiaomi (~8 years ago), and somehow got that on his phone as a trend.
Yea I have that too, its from garmin. It is the source of my weight tracking data
@bonifartius ultimately a long-term trend is what i have to rely on. A rolling average wont really solve that as it still presents a lag by nature.
