Hello, I am new to this community and to Victron. i have a phoenix 12|1200 inverter and a Bluesolar mppt 100 | 50 charge controller. Can I monitor both devices with one bluetooth dongle? How do I connect everything correctly? I am interested in monitoring the output of my panels, charge/discharge of the batteries, and consumption of my off-grid house. Thank you very much ---

@arstrube No you need two BT dongles. One on each device. The dongles connect to the VE direct port. Monitoring your battery State of Charge requires a smart shunt (has its own Bluetooth) as the Phoenix only uses voltage. The other option is a Cerbo S and ve direct cables. Not sure how that will pan out cost wise where you are. ---

Thank you Alexandra. I am beginning to wrap my head around this… Currently, there is a chinese TR16 battery capacity meter which has a normal (not smart) shunt. I will ask a local technician about how to proceed from there; obviously there is much more to it than just connecting a bluetooth dongle… ---

The mppt and inverter will appear in one app though. They do a live broadcast or [instant readout](https://www.victronenergy.com/media/pg/VictronConnect_Manual/en/stored-trends---instant-readout.html#UUID-a249901a-7ebe-9a66-3146-b9f5bb5c77af) ---

I have put the dongle on the MPP and it works more or less fine for monitoring the battery. My inverter, however, doesn not seem to have VE.direct. Instead, it has a green connector for two wires that I don’t know what it is for. According to the manual I downloaded, there should be a VE.direct in that place. Perhaps I have an older model? The only thing that occurs to me is to put a standard electricity meter in the power outlet where everything is plugged in. With that, I could at least manually establish some values for my power consumption. ---

What inverter to do you have? [This one](https://www.victronenergy.com/inverters/phoenix-inverter-vedirect-250va-800va)? VE direct is usually a white plug close to the green h/l remote connector. Unless you have a completely different inverter? A power meter will work as well. ---

well yes but not… perhaps an older model of the same… ![inverter](https://europe1.discourse-cdn.com/victron/original/2X/1/1dce85cdcffc8c5134becebb3aecc4e49c33a3b4.jpeg) I will use the power meter. With that, I can know the power I use each day and at least track that manually. ---

It is a shame the Victron BT dongle doesn’t have any data logging. For the price I would expect 30 days of data. ( The BM2 12/24v battery monitor logs 30 days of data and can save/export as a .csv and costs approx £15 or so.) So, is there any third party app which would log the data received in the Victron Connect app?? ---

You need a Bluetooth dongle for the 100/30 smart mppt charge controller? Doesn’t it have one built-in? Can my controller connect to my Phoenix 24/1200 the same way two controllers can? ---
