 ===== Introduction =====
 The VE.Bus Smart dongle is a Bluetooth Smart enabled VE.Bus interface, with battery temperature-and-voltage sensing. It communicates system information straight to your smart phone - using the free-to-use [[https://www.victronenergy.com/support-and-downloads/software#victronconnect-app|VictronConnect app]].
+The VE.Bus Smart Dongle does not provide full programming functionality - please also read this [[https://docs.victronenergy.com/victronconnect-vebus.html#ve-bus-smart-dongle-limitations|VictronConnect VE.Bus manual]] for more specific information on programming limitations.

-When used with Multi- inverter/chargers the dongle provides //on-battery// temperature and voltage sensing capabilities - allowing compensation for possible cable losses which can occur during charging and discharging. Temperature sensing allows accurate temperature-compensation during battery charge cycles.  On MultiPlus-II models the dongle is, at present, the //only// way to add an "on-battery" sensing capability.

Temperature sensing allows accurate temperature-compensation during battery charge cycles. The dongle is, at present, the //only// way to add an "on-battery" sensing capability to the MultiPlus-II models, if they are not also connected to a [[venus-os:start|GX device]] and CANbus battery.
-The dongle can be used in systems with or without a Venus device - such as the CCGX. In systems //with// a Venus device, the dongle will not override temperature and voltage information already being supplied by the Venus device - in this role the dongle will provide live-information via its VictronConnect interface; and it will provide no-internet firmware updates.
+The dongle can be used in systems with or without a [[venus-os:start|GX device]] - such as the Cerbo GX. In systems //with// a [[venus-os:start|GX device]], and another source of temperature and voltage data (eg from a CANbus battery), the GX device data will override temperature and voltage information from the dongle. In this role the dongle will still provide live-information via its VictronConnect interface; and it will provide firmware updates without requiring an internet connection.
-When the dongle is used in systems which //do not// have a Venus device, the dongle's voltage and temperature data becomes the primary source of that information, and can be used by other connected devices for voltage compensation. Thus, the VE.Bus Smart dongle can be part of a VE.Smart network ...sending voltage and temperature data to other Smart network devices.
+When the dongle is used in systems which //do not// have a [[venus-os:start|GX device]], the dongle's voltage and temperature data becomes the primary source of that information, and can be used by other connected devices for voltage compensation.
+In systems with a Multiplus-II, dongle and [[venus-os:start|GX device]], but no other source of temperature and voltage, the data from the dongle will also be used.
+At this time, the VE.Bus Smart dongle cannot send its temperature and voltage data as part of a [[https://www.victronenergy.com/live/victronconnect:ve-smart-networking|VE.Smart network]].
 The VE.Bus Smart dongle is able to sense battery temperature in two ways: The default method is the dongle's on-board temperature sensor. When the dongle is mounted directly onto the battery case (using its adhesive attachment) it will sense the battery temperature directly from the battery casing. The second method - which provides improved battery temperature sensing - is available by using an optional //battery-terminal// mounted sensor. When this sensor is connected, the default sensor is overridden and the dongle will use this method instead.
+The terminal connection on the VE.Bus Smart dongle marked 'Relay' has no function, and is not used.

 ===== Modes of operation ====
-The dongle can operate both as a //primary// and a //background// information source. It will assume either role automatically depending on whether a Venus device (CCGX/VenusGX/OctoGX) is present in the system.
+The dongle can operate both as a //primary// and a //background// information source. It will assume either role automatically depending on whether a [[venus-os:start|GX device]] (Cerbo GX) is present in the system.
 Due to restrictions in the VE.Bus communication protocol only one device can access data such as power readings.
-A Venus device has priority over the dongle and should always be able to access all data. When power is applied to the dongle - or after a firmware update - the dongle will startup in //background// mode. VE.Bus communication ports will be monitored for 30 seconds. If during this time no Venus device is detected the dongle will switch to //primary// mode, and all supported data will be available. While switching modes //VictronConnect// will temporarily indicate an "unknown" VE.Bus state. The dongle continuously monitors Venus device activity on the VE.Bus. As soon as a Venus device is detected it will switch itself to //background//  mode.
