V3.70 beta - WS500 over RV-C now working

Running the latest beta (not sure exactly when this changed, but recently) I noticed that my WS500 is finally showing as connected over RV-C. This is great!

It’s an issue I was trying to figure out for a year and appears to have been resolved but I don’t see any mention in the release notes. Here are my system details:

Lithionics BMS and WS500 are connected to the RV-C bus which is connected to the can port on the Cerbo. BMS and WS500 are configured as directed by Lithionics so the BMS directly controls the WS500 over RV-C. This works well. The Cerbo has DVCC enabled, and controls the MPPT. For some reason the WS500 would never show up as a device on the Cerbo, but the BMS and everything else on the RV-C bus shows up fine.

If I temp switch the protocol on the Cerbo can port to ve.can, I see the WS500 as a device but the battery drops offline. This never made sense to me because the BMS and WS500 speak to each other over RV-C, but the alternator would never show up as a device and the BMS would. Fortunately this is finally fixed!

It would be nice if a control was added to turn the alternator charging off.

I have the WS500 feature in wire which is set to disable charging and passes through the Victron Lynx BMS ATC relay also passing through one on the Cerbo relays which is on manual control so that I can disable the WS500 at will. On days with loads of solar I can do without alternator charging.
