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

Why did you choose this product over others?:Works perfectly. You really do get what you pay for

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.

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 .

As with all my Victron equipment, it feels over priced but build quality is good and I know when I eventually get to the point where I can switch the whole build on for the first time it will work. Cant comment on Bluetooth connection as it has t been tested yet.

Great thanks

Fantastic addition to a non Bluetooth mppt 75 / 10, plug and play, recommended.

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.
