I have the Blue Solar mppt with the dongle and the Blue Smart battery charger hooked up to my trailer battery bank. I can see both on my phone app. I guess I got one of the newer dongles.Also worth noting that if you intend on doing any VE Smart Network stuff (ex: transmitting temperature/voltage from a BMV or Smart Battery Sense) you're better off getting the SmartSolar. I had the bluetooth dongle for my BlueSolar to give it bluetooth communications, but apparently an older dongle model that is incompatible with the Smart Network. Could have bought the upgraded dongle for ~$50 but opted to just replace the old controller with the updated SmartSolar one. If you're finding them for similar prices, SmartSolar all the way.
Sure, I can see things in the app too - but the bluesolar can't communicate with the Victron SmartNetwork (created by a BMV or smart battery sense) if you have the older dongle. Bluetooth connectivity, yes, but allegedly some hardware limitation with older dongles that won't let it receive voltage/temp data from the networkI have the Blue Solar mppt with the dongle and the Blue Smart battery charger hooked up to my trailer battery bank.
