Hello janekx,
I bought this https://www.victronenergy.com/accessorie...-interface. It should be connected to Victron CerboGX USB port. The other side should go to https://tinycontrol.pl/en/accessories/bo...odbus-rtu/ - I plan to connect only A+, B- (so without Rx, Tx, aux power +3.3V). I'll let you know, if it works.
