I have a Smartsolar 100/50. How do I access the RX Port function on Victron Connect? It does not show up as a function when I am connected to the app. I am trying to remote on/off the charge controller from my BMS using the VE.direct RX pin. Under settings I can see 1. Battery. 2. Load Output. 3. Streetlight 4. TX port function 5. VE Smart networking. Where is the RX Port function?
