Easysolar II GX 48/5000/70, as per the title the system has lost visibility of the VE-Direct connected battery monitor corresponding with the point 3 days ago when i updated the GX device to 3.51.
I have tried unplugging and replugging the VE-Direct cable and waiting several hours each time for it to show up.
I am hoping someone here might recognise the problem and point me to the obvious solution 
Often after firmware updates it is worth rebooting a second and sometimes a third time to sort issues like this.
If no joy then go back to the previous stored firmware. If it reappears then raise the issue in the new gui topic.
