Recently I've added Interface 1140 to my setup, ever since adding it the DMC displays "Error 7" after switching to on or charger only. It displays the error for several seconds after which it turns on normally. The assistant is loaded correctly in my Quattro.
My system contains (all working as intended and on the latest firmware):
VE.bus - Interface 1140, Quattro(1931209), Cerbo, Digital Multi Control (connected in this order)
VE.direct - Cerbo, bmv-700, bluesolar mppt
When I disconnect the Interface 1140 everything reverts back to normal.
Can anybody shed some light on this?
