Has anyone connected to the Rx pin on the Smartsolar charger? I have a Victron 100/50 Smartsolar that I would like to control with an ignition 12v sensing lead. According to the VictronConnect bluetooth app there should be an option for the Rx settings to turn the VE.direct pin on/off but it does not show up in the App. Victron sells the non inverting VE.Direct cable that maybe controls the pin but why does the Rx option not show up in the app? The Rx pin should turn on the charger when it senses a 12V signal and turn off when it goes to 0.
