Hey People,
I got a sunbooster grid, this is a battery, that can be charged over AC and can inject AC into the grid/house. Currently, I can only control using the app, the vendor does not seem to open up anything. So time to reverse engineer.
- It seems, there are no open ports
- When I use the app, the station talks to
ec2-18-199-183-102.eu-central-1.compute.amazonaws.com but this is all TLS
- There is a option to use Bluetooth to set things up initally.
@Patrick762 I saw you contributed to making Bluetti stations available. What would you recommend?
Are there any experts interested into looking into wireshark recordings? I recorded three app launches.
Hi, same problem here. With Power Station Grid (without +)
I once had the idea to connect a hub to the WLAN access point, then using wireshark to log the communiation. Then send some specific commands via the app and see what it does on the communication. And then send those commands to the Grid. However I guess that would not work, because the Grid would not accept the commands from somebody else.
But actually the app tells me that I am connected via bluetooth. So maybe it is still possible to reverseengineer the bluetooth connection?
What I did so far was this:
-define charging times when I usually had sun on my PV, around 400W.
-define discharing times to cover the sendby consumption of the house 200W evening, night and morning.
-added a smartplug which I controled via Homeassistant switched durnig the day if I have excess power >400 going back into the grid
-measure the power from or to the power station and switched the switch off if the power was <50W. So switchoff when the Station is full or empty.
Bluetooth, is (allegedly) only for setting up WIFI. Found that in another forum. And I confirmed by standing near by with mobile and wifi off, but bt on. => no Control possible.
