Today we’ve released Venus OS v3.64, a point update focused on stability improvements, bug fixes, and refinements from recent versions.

Fixes & Improvements

• GX GSM & GX LTE: Improved connection stability, especially for Dutch KPN users on IPv6. New diagnostics: PPP and mobile network registration status.
• System Detection: Fixed device/system capability recognition issues seen on some units during boot, including Dynamic ESS and BMS/DVCC functionality.

New UI

• DVCC Charge Voltage Limit: Fixed incorrect rounding up of decimal voltage inputs. It’s now possible to set more precise values using decimals.
• Boat Page: Fixed Watts/Amps toggle (was stuck on Watts), and resolved gauge auto-scaling reset issue.
• Battery Page: Restored access to the System page for Lynx Smart BMS and similar battery types.

Venus OS Large / Node-RED

• Fixed an issue introduced in Venus OS v3.60 where initial values were not sent on GX startup or Node-RED redeploys when using nodes configured to only send on change.
