I have two instances of Node Red: One on my CCU3 (Redmatic) one on a separate host. I was able to connect to the CCU from both instances but they don´t provide the same value?!? Via RPC Events i get the same message output, but via "get value" the left one (external Node Red) shows "Error: unknown datapoint BidCos-RF.LEQ1202251:4.VALVE\_STATE" whereby the exact same statement on the right one (Redmatic) provides the expected payload:
