Victron EnergyVE.Direct Smart Dongle (Bluetooth) - Wireless Data for BMV & MPPT - View on iOS & Android with VictronConnect App

Works Great ! Also prompted a SW update on this device as well as the inverter . You must remember to have the Inverter in full power mode marked with two lines otherwise the Bluetooth doesn't power up .

Useful addition for the Victron MPPT controller to enable efficient battery charging based on voltage and temperature.By measuring voltage at the battery bank terminals, errors arising from voltage-loss due to cable resistance are avoided - guaranteeing the correct charge-voltage. For lead batteries, battery temperature data is used to adjust the charge-voltages: cold batteries require an increased charge-voltage, whereas hot batteries require a decreased charge-voltage. For lithium batteries temperature data is used to disable charging when they are too cold: charging lithium batteries near or below freezing causes permanent damage to the cells.No additional wires needed between the two unitsVery easy to set-up and connect to both the app and the Victron MPPT via their VE.Smart Networking:1) Start by connecting to the newly installed battery sense in the App (it will automatically suggest to update firmware if required (If you have an active 4G or WiFi on your device).2) clicking on the cog and the VE.Smart Networking allows you to either create or join an existing network3) If MPPT is not already on a network, you then just go back into the MPPT controller, to the cog icon then to VE Smart Network and then join this product to the network.Hey presto! all done!No issues with the Bluetooth range and you are left with a tidy setup

Great wee gadget. Very easy to install and use. Gives you great information on what's going on with your power.

It's nice to have but very little info. It tells you there's a load on a scale of low to high but doesn't give you any numbers. Good for changing settings and keeping an eye on battery voltage if you have a basic setup. Could be better.

No issues connecting to my Victron unit andsetting up the software on my phone and getting connected. It now means that I don't have to go into the back of the van and look in the cupboard to see if the battery is being charged and at what phase. A bonus is that it also tells me the condition of the leisure battery.Has a transmit distance of around 20 to 30 feet (sorry, I old school).Screen shots are from my phone taken when connected to van 20 feet away.I wouldn't say it's an essential item, but for me, I feel it's an essential item and I don't know how I lived without one

Wow this solved my issue of the solar controller thinking my lithium battery was full due to the caravan wiring and backing off the solar input. Very easy to set up on the Victron App small and inexpensive.

Having lost a pair of batteries in my Land Cruiser when the Alternator went on the frizz I wanted to make sure that the charging system and new batteries and alternator were all working ok. The Sensor was simple to install as the eyelets bolt directly to the battery terminals. Once I connected the Victron Connect app on my phone to the Sensor, the app immediately downloaded new firmware for the Sensor. It rebooted and connected to my phone app at once, displaying the voltage and temperature of the battery (or pair of batteries in my case).I've included a screenshot showing the background voltage of my batteries (12.7v ie 100% charge), the voltage dip as the starter motor turned the engine over, and then the initial charge voltage when the engine started, a perfect 14.2v from the new alternator.Exactly what I needed to know, everything is working perfectly in the LC.The story doesn't end there. I also have an old campervan and I'd like the same confidence in its charging system and starter battery, the battery being at least 6 years old. My solution was to buy some industrial velcro on Amazon and put the bluetooth sensor in a tight pouch of female velcro. With a strip of male velcro stuck to the top of the battery, the sensor can be moved from vehicle to vehicle as required, once unbolted of course.

Great thanks
