What is this?
The EasyWallbox worked fine for me until I installed FV Roof Panels on my house and I want to use the solar excedents to charge my car during the day.
On the EB configuration I can set the charge limit, the safe and the DPM limit
DPM = Dynamic Power Management
But the DPM only works to balance the charging between the house consumption and the setted charge/safe limit.
What I need it's top ballance the charging between the Panels, house consumption and the DPM, at this point I am able to know how many kWh I get from the Panels and how many kWH I use at the house, so I have 2 options:
- Buy a new Wallbox that it's able to do what I need, but this will cost me at least 800€
- Connect to the Wallbox via BLE and change the safe or charge limit according to how many electricity I get from my Panels, for this I need to buy a bluetooth adapter for my HAL9000 and this will cost me a 8€
Open your linux terminal and run :
hcitool dev
If you don't get any info you have to reinsert the Bluetooth dongle
Now run a low energy scan to get all the available BLE devices:
sudo hcitool lescan
At this point you get you Wallbox mac address in this format 00:00:00:00:00 (save it for later)
To connect with your android/ios device you have to scan a QR Code that's it's available on a sticker inside your Wallbox and after that probabilly you get a message in the app telling you the pin code it's 001234, no, it's not this code it's only to use it trought the official app.
How to get your code.
Open your camera / QR Code reader and point it to the sticker. You will get something like:
BT:N:2911AA00101728;M:F2ME.EWE08APEFXX;D:eWB01728;P:001234;A:9844;;
Let's decode it:
N: Serial 2911AA00101728
M: Part Number F2ME.EWE08APEFXX
D: BT Name eWB01728
P: Device Pin 001234
A: BLE Pin 9844
We need the A: value, in my case it's "9844" (save it for later)
