Node-RED node for listening RuuviTags.
This is pretty much just a thin wrapper on top of node-ruuvitag.
It listens to all RuuviTags in range and puts content of received messages without modifications to msg.payload. RuuviTag ID is added to msg.topic (with configurable prefix).
Scan interval controls how often scanning is performed and results forwarded.
Scan time controls for how log scanning remains active. Default RuuviTag firmware sends data in BLE advertisements once per second, but sometimes advertisements might get lost and it's probably best to set this to a few seconds or so.
Not really tested, but works for me on RPI 3.
