Yeah, I got turned off when I realized you can’t sync these devices via Bluetooth or LAN.
Required path is: Scale data -> WiFi -> Internet -> Withings app -> HealthKit
Is that my problem? I figured that WiFi access was enough to hit my phone to update HealthKit, but I never gave the scale access to the Internet ("you can go live over there on the IoT VLAN with the other tattletale devices").
Well, fuck that. Now I'm really, really, really not going to buy a Withings product again.
Seriously? That’s awful by design. I figured it was BT from scale to phone app.
There’s an HA integration path for the scale to HA but I don’t believe anyone has yet built the HA to HealthKit side of that.
