Followed the " Victron & Pylontech UP2500, US2000, US3000, Phantom-S & Force-L1" instructions and used a made (& tested) cable according to the "VE.Can to CAN-bus BMS cables manual" and have no apparent comms between the Color Control GX (firmware version) and the US 2000 master CAN RJ45. The Pylontech US 2000 is operating as "normal"and the batteries are fully charged. Just upgraded the MultiPlus 48/3000/35-50 to firmware 473. DO not see the Pylontech in device list.
