See Subject Line Above, just bought 1030, has no sensor option for weight scale. What are you thinking?
The weight scale would typically send the data to Garmin Connect and then Garmin Connect will download it to the Edge.
What scale are you using?
Tanita, historically, on past Garmins, the Edge would take the weight info and yes, post it on Garmin Connect, but now, there is no mechanism for taking such info, because the 1030 doesn't have an option for weight under Sensors.
There is an connect iq app for it, but Garmin has its own scale that uploads to connect and the weight is transferred to the 1030
