EVCS NS keep disappearing all the time need to be discovered from modbus device list.
If wvcs is lost did not charge on auto charge mode.
I don’t know what else i can do i tried all option.
Can be hardwire to cerbo?
Start regretting to buy this one.
This also happened to my EVCS after doing a yearly round of firmware updates. It is connected properly as I can use it on Bluetooth and directly through its IP adress from the same LAN as the Cerbo. Testing the connection to cerbo from within the EVCS also gives a green OK and the IP adres is shown in the modbus list on CERBO.
I think its something in the Cerbo firmware itself because eventhough the device list in VRM states that it has not been found for over a day if I Click “Control panel”it opens the control panel of the EVCS as if nothing is wrong. however it won’t show up in the device list on the console.
Because of the intermittentness of this issue I build a workaround in Node-Red that calculates and then sets the charge current etc in the manual mode comparable to what the auto mode does. For now this works for this case but I would like an update on a solid-solution from Victron to not run into issues for other use-cases. the way the EVCS integrates in the rest of the Victron systems has been a treat before this happened so I hope there will be a fix.
can you fill me in about your node-red settings?
