BMV-712 power consumption with bluetooth on vs off?

There are several threads about the power consumption of a BMV-712. I know it's less than <1mA when connected to a ~24V pack with the backlight off. What I'd really like to know is what is the difference in consumption with Bluetooth on vs off. Assume "on" means just the device sitting there available for BT connections, but with no actual usage. I'm looking for the difference in leaving the BT on for a weeks/months.

It has to be less with it off, but I'm wondering how much less.

Blue Smart IP22 Charger and Global Link 520

Will the BlueSmart IP22 charger communicate with GlobalLink 520 over bluetooth?

I don't see it on the lists, but seems odd because it supports Bluetooth Instant the same as the rest.

Pre purchase qualifier in my case.

Multiple bt dongles??

Would it be possible to have more than one bt dongle attached to the cerbo? I have an external bt dongle plugged into the cerbo because of the issues with the internal bt disabling on high temp. I have 2 mopeka pro LP sensors in the rear compartment and because of the distance and the steel bulkheads they don't always stay connected. Would it be possible to run a USB extension cable to the rear compartment and plug in another bt dongle?

Instant readout parameters for Phoenix inverter

I was just trying a Phoenix 12/500 inverter with a VE.Direct to Bluetooth dongle, and while this works well in the "logged-in" mode, the instant readout only displays the battery voltage and inverter state (inverting/searching/off).

Since there are only two other parameters available for readout (in the "logged-in" mode) from this device, namely the AC voltage and the % load, could these not also be included in the instant readout?

In particular, the % load is perhaps the most useful parameter to be able to see.

EasySolar-II GX 24/3000 with USB BT dongle for Ruuvi and Mopeka sensors


I'm trying to build a solar system around an EasySolar-II GX 24/3000 and I'd like to attach a USB Bluetooth dongle to it, like TP-LINK UB5A, or something similar.

I need this for connecting to Ruuvi temperature sensors and Mopeka tank level sensors and the internal GX module of the EasySolar does not have BT.

The ultimate goal ofcourse is to have all the information nicely available in VRM.

Anyone tried or knows if this can be done?

Thank you,

Bluetooth connection on Global Link 520

Hi there,

I added a Global Link 520 gateway to my configuration. Very simple basic architecture on a sail boat. I've got solar pannels charging batteries with a MPPT 100|50 controler which is running just fine. Also is a Smart battery sense. Both devices MPPT and the battery sense are successfully connected using Bluetooth and the MPPT controler receive infos (Temp and Voltage)

Now is the issue I am facing:

The global Link gateway is up and running with a good connection to LTE-M network. However for some reason which I don't understand the Global Link gateway will only see the smart battery sense using bluetooth. Nothing else. It can"t see the MPPT device. What is more the Global Link is installed 15 cm away from the MPPT !

I tried to power down/up the gateway .....same isse

I tried to remove (in the Global gateway setup) the smart battery sense ...... same pb it still will not see the MPPT controler.

I double checked the firmware version ...I am up to date and running V 2.06

The user guide mention we can have up to 10 Bluetooh device connected with the Gateway ...I won't have 2 ....only 1

Any clue ?
