Dazebox + OCPP

[jiripatka]

Any experiences with Dazebox ( guarantees 1.6 json ) control via ocpp? Daze Home connection is possible but only with older version ocpp 0.10.7, no option to turn charging on/off , unstable power control. Ends with red alarm with the need for factory reset - apparently conflict of control via ocpp and app ?

Daze Home + OCPP 0.10.13 on wired connection now working - diagnostics + Charge control. Not working Maximum current setting.

I’ve experimented, I’m not expert, no usefull configuration.

0/ Caution: if I leave OCPP enabled in the app and then delete the wallbox (WB) from the app, I can no longer see or restart it. I have to contact the Italians (whom I’d like to thank). This implies they have some form of online access to restart the wallbox.

1/ Via TCP over IP adress = RJ 45 B (not C for power manager !); normally, all ports are inaccessible. However, if you set WB to "slave" mode while adding the wallbox association in the app—there are several options, and I certainly haven't tried them all, something appears on port 502. Specifically, I see 4 entities, but no controls:
yaml:
modbus:

• name: dazebox
  type: tcp
  host: 10.20.30.xx
  port: 502
  timeout: 5
  delay: 2
  sensors:

  • name: "Daze Status"
    unique_id: daze_status
    slave: 1
    address: 0
    data_type -D: uint16

  • name: "Daze Amperage Limit"
    unique_id: daze_amperage_limit
    slave: 1
    address: 1
    data_type: uint16
    scale: 0.1

  • name: "Daze Voltage L1"
    unique_id: daze_voltage_l1
    slave: 1
    address: 2
    data_type: uint16
    scale: 0.1

  • name: "Daze Power Total"
    unique_id: daze_power_total
    slave: 1
    address: 4
    data_type: uint16
    scale: 0.1

2/ Modbus RTU = Contacts on the mainboard at the bottom: "SH GND A B" + Waveshare serial converter (RS232/485/422 to RJ45 Ethernet) + Modbus Poll software... It detects a signal, but I haven't managed to find a working configuration for the converter. It probably also depends on the WB setting in the app.

Hey,
just wanted to tell you, i ended up making my own daze integration, i just pull the data from the website and use that to manage the power of the charge.
Its less reliable than direct control, but for now it works and i can modulate correctly.

[jiripatka]

Congratulations - any more specific details? (I tried creating an "API" for https://webportal.dazeservice.com/login and EVCC integration in HA, but I wasn't successful, mainly due to the repeated bearer token authorization.)

[sypher01]

To be honest, i didn't really have the time to do it myself, i just made GPT + Local AI have at the problem till it was solved, then polished the home assistant integration a bit.
Now i have the integration with authentication, which pulls the data directly from the site every 30 secs, power control, enable charging and disable charging, etc ...

I talked to the company too, but they are quite 'meh', and i don't want to release publicly in fear that they will do changes so that it will stop working ...

I'll double check the repo for personal info and invite you there if you want

Thanks, it works !

Grazie ! :D

Ciao, posso chiederti anche io accesso? Can I ask acess as well? Many thanks

[sypher01]

direi che a sto punto la rendo pubblica, fammi fare un pò di polishing. @coloale
non so se gli altri la stiano usando e come va, a me va bene e ci ho integrato un controller per scegliere se ricaricare tramite grid, solare con prio accumulo o solare con prio auto ... (@Linskun ?)
direi lunedì vedo di aggiornarla.

Perfetto! Grazie mille
