- glogla 7y agoYou only get data from those when the phone is in bluetooth range. That's not very useful for long-term measurements. Unless you buy cheap android phone as a basestation I guess.
- lemming 7y agoI have a bunch of SensorPushes at home which do the same, but they store the data for up to 20 days iirc, so it's effectively continuous data unless both my wife and I go away for a month or so.
