Multiplus 2 and Pylontech US 2000 Plus usable without GX device?

I have an off-grid system with a Multiplus 2 , two Bluesolar Mppt 150/35 and 8 Pylontech batteries US2000Plus. Yesterday the Color Control GX stopped working (first it showed wrong values, then I tried to reboot but it remains with the "Victron Energy" start display).

As the Mppts stopped to charge I disconnected them from the CC and reset them with the parameters for Pylontech batteries. Now they charge correctly, short time after 100% SOC they change to absortion modus, and the Pylontechs go standby when fully charged and if there´s no load. Also the Multiplus works properly.

Can I continue to use the system in this way without any GX device or should I better shut it down until the new CC arrives?

I have not tried with the multi 2 but the manual states not to as it needs the keep awake.

See section 1.2

I dont know how your supplier stands on this but ours will not honour warranty on Pylons in an ess system if there is no GX device.
