Have you tried going back to settings and bluetooth to turn it off and on again to see if it re-sets?

Hi @cwsymons , and welcome to Community,

I'd expect its a signal strength issue. Can you try taking a Ruuvi closer to the GX Device?


And, in case you have a Cerbo GX including GX Touch, then, depending on the serial number, there might be an issue with how the WiFi/Bluetooth antenna cabling is routed in the unit. See document for details and how to correct:

Hi,

thank you for your comments. I would like to point out that I do not use a GX touch and that the Cerbo GX and the Ruuvi are approximately 3 metres from each other. The Cerbo GX could see 2 100% reliably and another 2 intermittently (which I was working on rectifiying). Now the Cerbo cannot see any Ruuvi bluetooth temperature sensors. Very odd.

Hi, clear thank you for the quick response. And odd indeed. I see you have the Remote Support feature enabled: is it ok if we login to analyse?

Hi again, we'd like to swap the unit and get yours in our lab. There is something strange going on, which we don't see on other units (except one other) and impossible to further diagnose on a distance. I'll get our Service dept. to reach out to you by email to arrange it; hope thats ok for you! thank you for reporting, this helps making a better product, Matthijs

Ps. I earlier wrote your Cerbo had serial number HQ2118, but thats wrong. But doesn't change anything, it would be great to get yours into the lab

Good morning from New Zealand. I am also having Ruvvi issues. Running Cerbo with GX touch, the Cerbo Bluetooth is dropping out, the only way I have been able to remedy is via a USB factory reset.

Hi @Wayne , hm thats unfortunate. Can we login to see the issue? For that the system needs to be on and on the internet, Remote Support setting enabled, and I’ll need the vrm url; which if you want you can send me in a private message. (See the viewable option when replying).

@mvader (Victron Energy) good afternoon, did someone have a play, my sensors were back on line this morning, the only thing I have done since posting was toggle Has DC off and on.

I have found another potential (38) issue which I will post as a seperate question..

Thank you..

Hi Wayne, thanks. Good to hear they are back. We looking into what is happening on some systems wrt the complete Bluetooth menu going missing.

We've got 2.83 installed and the Ruuvi's show up on phones several meters away but not on the Cerbo GX (serial: HQ2035xxxxx).

Any suggestions?

Yes: bluntly put: the bluetooth radio in the Cerbo GX is not reliable enough for this.

There is an issue with the internal temperature, when over ~53C it doesn’t work well, stops working, or doesn’t start. (Not sure).

The solution is to use a USB Bluetooth adapter. We’ve tested a few common models over the full temperature range; will share the results soon.

Basically all above means we change the spec for the Cerbo GX.

RMA-ing the device help. Its unfortunate, but luckily not that hard to solve. (By plugging in usb/bluetooth adapater).

Thanks @mvader (Victron Energy) - before we start advertising this to clients, can we confirm that this issue applies to all revisions of CerboGX currently in production or has there been a change made that means problem will not exist in newer models?

Hi @Warwick Bruce Chapman , no change in production yet. And for what we've seen so far, all Cerbos produced so far have this limitation.

Hi all,

I have 5 Ruuvi sensors connected to Cerbo GX (SN: HQ2048Q922V) via internal bluetooth. With firmware v2.82 it is all working OK. After upgrade to 2.84 or 2.85, no sensors are connected to cerbo gx. List in Settings - I/O - Bluetooth Sensors is enabled, but empty.

After rebooting back to v2.82, sensors are back and working again.

Thank you for response.

I'm running 2.85, I cannot get any more than 4 Ruuvi sensors to show up. Yes, ordering my name would be much better than ordering by id as others has mentioned. I am running on venus os on a pi, so a little different setup, but dunno if there are any limitations.

@mvader (Victron Energy) Also issues with the ruuvi tags here. Yesterday my touch 70 stopt working. (Possibly heat problem, the touch 70 was behind glas in full sunlight) To reactivate the screen I had to disconnect the power from the cerbo. After doing that the ruuvi tags didn't show up anymore. Already tried turning bluetooth off and on etc.. Ruuvi tags are all (3) within 50cm from the cerbo. I had this problem before but then after an update everything worked fine. I have read about the WiFi/Bluetooth antennas problems but it worked fine before. I will try to change the antennas this weekend because I also have a very slow reacting remote console.


Edit: meanwhile I did an update, to v2.90~8 (from v2.85) and now bluetooth disappeared from the settings screen!! I will try to go back to V2.85
