Color Control GX not communicating with Hubble batteries

Q&A and troubleshooting

Hi there, please assist

My client recently replaced his lead acid batteries with 2 x Hubble AM 2 5kWh batteries

Previously he had a Color Control GX and BMV700

We’ve disconnected the BMV and connected the Hubble Cloudlink and CCGX

The problem is, THE COLOR CONTROL GX IS NOT SEEING THE HUBBLE BMS

I have wired the installation according to the Victron and Hubble manual

I thought I’ve made a mistake, so I tried THREE different Venus GX devices. Everything worked

I also tried a Cerbo GX and everything also worked.

The Color Control GX is on the latest firmware that I could get on Victron Professional (v3.55)

From the sticker on the CCGX, I could see it was manufactured in 2019.

Is there anything that I am not doing right, or is it something associated with the age of the CCGX?

I have also tried a termination resistor, still nothing worked

The CCGX has a VE CAN port which defaults to 250kbps, BMSs typically use 500kbps. You need to make sure both havr tje same speed. A terminator is usually required on the CCGX.

I’ve put both the CCGX and the Cloudlink on 500kbps and used a terminator as well. Still nothing

Hi @Jonathan22,

Am I understanding you correctly that this works with other GX devices you tested, but not this specific CCGX?

If that is the case, it’s probably some fault with that specific CCGX?

I don’t know of any general issue between CCGX and Hubble. But in all cases now we advise using a Cerbo GX or Ekrano GX instead of CCGX.

There are load issues with later firmware versions of Venus OS and the CCGX and that can appear like some devices are not communicating, or very slow to connect. For this reason we have now discontinued the CCGX.

My first and best advice would be to update to a Cerbo GX.

If that is absolutely not possible and you would rather spend some more hours trying to troubleshoot it, then you could try an older firmware version of Venus, say v2.94 (this will require manual loading, and then you will not be able to any further updates into the future), strongly not recommended, but here for completeness.

Thank you, Guy. I finally gave up on the Colour Control, after several more attempts. We got a Cerbo and it’s all working fine now
