Wakespeed not showing Power Data on Ekrano GX

DIY

Hi,
I have an Ekrano GX system with the Wakespeed WS500 with a CAN BMS.
So I use the shunt from the WS500 on the alternator. But I do not get the power data on the Ekrano.

The Ekrano shows the RPM correctly, but only dashes at voltage, current and power. In the Wakespeed app and the PC software I can see the correct current and voltage. So the problem must be somewhere on the communication side. In dbus-spy the data is not shown either.

What could be the problem? I am using the latest Venus OS firmware.

Have you got RV-C CAN and NMEA2000 CAN subsystems enabled.

There is also a good Facebook group for WS500.

Hi, yes the RV-C and NMEA2000 are enabled, i also can see the data on the nmea2000 bus.
Does the Ekrano get the Data from N2k data or the direct SMA Protocol Data?

I always thought it was a subset of NMEA2000.

Here is another thought. My WS500 has been working fine with lead acid batteries. Today I swapped my boat over the Victron NG lithium and Lynx NG BMS. Updated the WS500 settings and last thing i checked was the engine run, no power shown just dashes. I checked the profile and found ignore local current sensor was set to yes, I do not recall changing that. I will have to wait until tomorrow to reload a new settings file.

Here is my current WS500 Config. {"summary":"Transportable configuration file created using the Wakespeed Applica - Pastebin.com

Your current sensor is not ignored. I found that the WS500 app set the current sensor to ignore when choosing Victron Lynx BMS and I did not notice, hope it fixes it for me tomorrow.

I have now had the time to download your file and input it into the Wakespeed app. From your file it looks like you have an REC BMS and a WS500 Pro, if only you had said that at the start, there is some problem with the V2.6.0 firmware when the REC BMS is combined with the WS500 Pro, I do not know if this is causing the misreading, as I have neither of these I have only paid peripheral attention to it. You may get more info on the Wakespeed Facebook group linked earlier. The only thing I was unsure of in your configuration is you have chosen Battery ID (Instance) 8, are your sure your battery is instance 8, mine is instance 1, but I would not expect that to stop the alternator power being displayed and as I have different BMS I am not too sure on this.

I can not offer any more suggestions, do let us know if you manage to get a resolution.

Secondly, I have solved my issue where I had the ignore current sensor turned on, now I see the power on the GX device.
