Today we’ve released Venus OS v3.65, which introduces new RV-C features and a few stability improvements and fixes.

RV-C feature updates

Venus OS for GX devices now has vastly improved support for RV-C connected devices and for integration into RV-C systems.

• RV-C In: Venus OS now listens to and integrates alternator regulators (including Wakespeed WS500, Arco ZEUS, Revatek Altion), and batteries such as Battleborn with DVCC support. This means the GX can natively read their operating status, limits, and charging requests directly over RV-C.
   
• RV-C Out: Venus OS can now actively report and control GX Generator Auto Start/Stop and alternator chargers (including Orion-XS and supported third-party regulators). This update also adds new messages for the Lynx Smart BMS NG, along with improvements and additional messages for chargers, inverters, and inverter/chargers. These RV-C Out messages allow other RV-C devices on the network to recognise, monitor, and control Victron hardware as native RV-C nodes.

For a detailed overview of the new RV-C features, see this slide deck.

Fixes & Improvements

• Fixed an issue that could sometimes cause login information to be lost when using Remote Console on LAN, requiring the user to login again.
• Node-RED on Venus OS Large:
  • Fix “Not connected to D-Bus” error on some nodes after doing a (re-)deploy from the flow editor.
  • Prevent crash of Node-RED when sending null or undefined for “text” when setting the status of a node.
  • Corrected grid meter frequency readings for EM540 and several other grid meters.
  • Improved first-time use of Node-RED by automatically including the required config node.
