No problem

Describe the solution you'd like

I use two of these 30A bluetooth powerqueen chargers: https://www.ipowerqueen.de/products/power-queen-12-24v-30amp-mppt-solarladeregler-und-bluetooth-adapter

It would be awesome if they could be supported as well in addition to the Victrons. However, there is currently no documentation of the protocol used. I already aksed Powerqueen but they didn't provide any infos.

Their smartphone app is the only piece of software right now that can communicate with these chargers:

I am not familiar with bluetooth traffic sniffing to do some reverse engineering on my own. If anyone can guide me i may contribute more infos, but that is all for now.

Describe alternatives you've considered

Bluetooth may be complicated but the charger should have a rs232 or rs485 port. so that’s something to work with.

Can you capture data from this port and provide it here?

[itscz-org]

It has rs485 but i don't know how to utilize it

I ordered an USB-RS485 cable i will try if i can get any infos from it.

Just an update: The cable didn't fit, it had an 8pin RJ45 connector whereas the charger has something smaller (6pin?). So no progress here yet.
