No Ruuvi Bluetooth Sensors found

I connected some Ruuvi Tags a while ago. Since today they are missing in Cerbo GX. In Bluetooth Sensors menu no sensor could be found. The sensors works with my smartphone. Any tips for that?

Did you upgraded your firmware on the GX-device? When upgraded tot 2.19.10 I needed to enable continuous scanning in the Settings - IO - BluetoothSensors menu.

Hi @wima

Are you using the built in bluetooth, or an external USB bluetooth dongle?

The built in bluetooth is not supported for Ruuvi sensors as it is gets disabled due to temperature - so is only suitable for the initial commission setting the networking configuration - there is more detail in the Cerbo GX manual here - https://www.victronenergy.com/media/pg/Cerbo_GX/en/installation.html#UUID-4d5df29c-761e-cfcc-9e2c-8230f126e7bb_section-idm4637103287267232851365842652

Is this a new safety feature? As I only updated the Cerbo a few days ago.

I've never seen mine cut out, today has been pretty cool and I've lost all Ruuvi.

I'm not even showing the Bluetooth Menu under I/O. I tried rebooting also.

I have no external USB dongle. I powered off Cerbo GX for a while and now it works again. Do I have to use an external dongle? Which one could you recommend?

I think I have to buy one that is available in Switzerland. For example the TP-Link UB400. Do I have just plugin the dongle into the Cerbo GX? How the ruuvi tags know with which device they have to communicate? Or is the internal bluetooth disconnected when I plugin a dongle?

Mine cut out today again and as soon as I plugged in the Bluetooth Dongle it worked.

Reading another thread you can have multiple dongles connected and it will all work together. Not sure whether the internal one disconnects or not.

I used a TP-Link UB4A.
