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. 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|Venus-device]] and CANbus battery. | 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.

The dongle can be used in systems with or without a [[venus-os:start|Venus-device]] - such as the CCGX. In systems //with// a [[venus-os:start|Venus-device]], and another source of temperature and voltage data (eg from a CANbus battery), the CCGX 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. | The dongle can be used in systems with or without a [[venus-os:start|GX device]] - such as the CCGX.

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|Venus-device]] (CCGX/VenusGX/OctoGX) is present in the system. | The dongle can operate both as a //primary// and a //background// information source.

A [[venus-os:start|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-os:start|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-os:start|Venus-device]] activity on the VE.Bus. As soon as a [[venus-os:start|Venus-device]] is detected it will switch itself to //background// mode. | A [[venus-os:start|GX device]] has priority over the dongle and should always be able to access all data.

Likewise, the dongle also monitors VE.Bus communication in order to discover if a [[venus-os:start|Venus-device]] is supplying the //Multi// with battery voltage and temperature data. It takes around 4 minutes after power on, or reset, before the dongle decides whether or not to transmit the battery voltage and temperature. | Likewise, the dongle also monitors VE.Bus communication in order to discover if a [[venus-os:start|GX device]] is supplying the //Multi// with battery voltage and temperature data.
