RuuviTag knows exactly when it’s moved. Known when the postman opened your mailbox outside and get notified if someone visited your hotel room while you were gone.

Pairs with a Victron Energy Cerbo GX
This product is a great way to add this type of data to your Victron Cerbo GX system. Check out this Victron Energy tech talk where they discuss this. Importantly, you’ll need to have Venus OS v2.80 or later running on your Cerbo GX. Also, the integrated Bluetooth connectivity on the Cerbo GX is not strong enough to support the Ruuvitag so they recommend that you add a third-party USB to Bluetooth adapter. Below is a list of these that have been tested by Victron Energy to work well. These are all in the $10 range.

  • Logilink BT0037
  • TP-Link UB400(UN) – this is the one we used
  • Ewent EW1085R4
  • Laird BT820
    Laird BT851

Of course, you can also use the sensor with Ruuvi’s own app which is available for iOS and Android devices.
