Yes it does that now, and that’s ok. I have three RuuviTags and it looks like the app sends the latest scan from any of them. When I create a dashboard (on freeboard.io) for the dweet I can pick out what data I want to show, so it works there. But when I check my dweeted thing on dweet.io it looks like I said.
You can look at my RuuviTag thing here: https://dweet.io/follow/Vallgrund-Ruuvi
This is the url I enterd in the app: https://dweet.io/dweet/for/Vallgrund-Ruuvi
And in my case when I have three RuuviTags that are scanned continuously, it would be nice if the app could send data from the different RuuviTags to their own dweet thing.
