How do I get the Cerbo GX to feed Smart Shunt data to Skylla-i charger, supply amps and batt temp inputs to the charger’s algorithm. Setup: () Skylla-i charger’s output goes to a 24VDC buss. () The Skylla-i charges one of two 24VDC battery banks that are connected to the buss. () Both banks are …

You are correct, the Skylla reports its output, some of that goes to loads so the battery current on the SmartShunt is lower. The usual mechanism of sharing battery voltage, temperature and current from a SmartShunt to the Cerbo GX and to other connected devices is DVCC. The Skylla chargers are not…

Thank you! I will give it a try. Good to learn how it works. Skylla docs say must use temp compensation if either (a) batt temp > 30C and the boat will be in the tropics where both the air and water temp will exceed this; and (b) charge current exceeds 15A per 100Ah batt capacity, and we are charg…

See attached Cerbo screenshots. There are three shunts. In the DVCC screens, Cerbo is using the “product name” instead of the “custom name” for the Shunts. Therefore I’m at a loss as to how to select the right shunt. In the device list it uses the “custom name”. [Shunt List] [Selected Shunt] [D…

If the absorption can be terminated by battery tail current then it will go to float earlier. With temperature compensation, at temperatures above 20 or 25degC the absorption and float voltages will be reduced. In terms of setting the master battery monitor I have not done it myself with identical …

OK. Is there a way to read what the Cerbo is “publishing” as the STS/SVS/SCV values? This would be useful for debugging. With that I could probably also figure out the “order” that it has the devices, and chose them based on their position in the list. OMG that’s disgusting. But not as disgusting as…

I do not know, I will raise this with the expert users. I suggest you make a new post titled selecting one SmartShunt on Cerbo as battery monitor.

Hi @GAjet , Thanks for the report, I have escalated it to the Venus OS team to look into how this can be better handled. Hopefully a quick fix.

Hello Guy. Thank you for escalating. Much appreciated. Did anything come of that? Also, I was wondering if escalating the other bug would be appropriate: How to fix an infinite power cycling loop? Thanks in advance.
