Wakespeed WS500 and Cerbo GX without BMS, NMEA2000 data from Cerbo to WS500

I am about to install a Wakespeed WS500 alternator regulator and connect it to the Cerbo GX. I currently have a large AGM battery bank so there will be no BMS involved and I do not have an NMEA2000 network, so only the Cerbo and WS500 connected by the WS500 to Victron cross over cable with CAN terminators on both devices. I want to have the WS500 shunt on the alternator output and have the WS500 pick up the battery current and temperature via NMEA2000 from the BMV702 battery monitor via the Cerbo GX. This option is not covered by the Cerbo GX manual nor on the WS500 site.

On the WS500 in the $CCN I have set "ENABLE_ALT_CAN" to "NMEA RAT" (value 1) which the config guide states as the WS500 receives battery current and temperature via NMEA2000 from the battery monitor.

On the Cerbo GX (after reading the manual) I plan to set "NMEA2000-OUT" to on. Is this all I need to do to have the NMEA2000 data output transmitted by the VE Can port for the WS500 to accept and interpret.

@pwfarnell, I'm currently installing 2 on a catamaran, also with a shunt and Cerbo.

As I understand, they will only work with a shunt when the Wakespeed has FW version 2.5.1 installed. The units I have are both 2.5.0. I have not been able to update the FW through eitther the batch file, or the Android app - the Android app keeps saying that then latest FW, 2.5.0 is installed!

Have you had any luck installing FW 2.5.1?

Yes, I got mine to 2.5.1, you may need to update the app first as a new version 1.6 of the app was released at the same time. Another way may be to download the firmware to your phone then update it. Firmware files are found on the following page, the link is under "Latest Firmware"
