This is an important update.
Another reminder! On December 6th 2018, Google will stop delivering Android Nearby messages.
If you’re using your RuuviTags in URL mode (to receive Nearby notifications), please switch to RAW mode.
Note that by using the RAW mode, you’ll also receive sensor data in better resolution.
Note also that if you don’t mind to read your devices in low resolution, Ruuvi Station also supports the URL mode. So updating firmware is not mandatory but recommended.
Find full operation manuals of both RuuviTag and Ruuvi Station here:
