以下功能提供了Modbus寄存器到HTTP的映射。
注意:Modbus不需要激活即可使用HTTP API。
使用HTTP GET或POST請求到cFos Power Brain Controller的地址,例如http://192.168.2.111/cnf?cmd=modbus&device=meter1&read=35154
。
響應使用JSON。
cmd
始終是modbusdevice
= meter1或meter2或evseread
=要讀取的寄存器地址write
=要讀取的寄存器地址value
=要寫入的值values
=要寫入的values
數組,例如[1,2,3,4]地址可以有一個後綴以指定數據類型(默認為16位整數):
d
= 32位整數(2個Modbus寄存器)q
= 64位整數(4個Modbus寄存器)s
=字符串/cnf?cmd=modbus&device=meter1&read=8002
響應:
1
/cnf?cmd=modbus&device=meter1&read=8062d
響應:
-1
/cnf?cmd=modbus&device=meter1&read=8016s
響應:
"cFos Power Brain"
/cnf?cmd=modbus&device=meter1&read=8002&count=10
響應:
[1,257,256,0,256,0,26211,26165,11619,13366]
/cnf?cmd=modbus&device=meter2&read=all
響應:
{"8000d":-821755904,"8002":1,"8003":257,"8004":16777216,"8006":256,"8007":0,"8008s":"fcf5-c46d-310c","8016s":"cFos Power Brain","8040":41,"8041":1,"8042d":1000,"8044":1,"8045":230,"8046":230,"8047":230,"8050q":0,"8054d":0,"8056":0,"8057":0,"8058q":0,"8062d":-1,"8064d":0,"8066d":0,"8068d":0,"8070":0,"8071":0,"8120d":0}
/cnf?cmd=modbus&device=evse&write=8044&value=7
響應:

/cnf?cmd=modbus&device=evse&write=8050q&value=1"
響應:

/cnf?cmd=modbus&device=evse&write=8044d&value=1"
響應:
"bad modbus register size"
/cnf?cmd=modbus&device=evse&write=8044&values=[7,230,230,230 ]
響應:
"ok"
請求所有Charging Manager設備的狀態:/cnf?cmd=get_dev_info
設置 PIN 或 RFID:/cnf?cmd=enter_rfid&rfid=r&dev_id=d
r 是 PIN 或 RFID(數字),d 是用於選擇特定牆盒的可選設備 ID。如果未選擇設備 ID,充電管理器會嘗試自動分配 PIN 或 RFID。
覆蓋當前事務:/cnf?cmd=override_device&dev_id=d&flags=f&mamps=ma&rfid=id
d 是設備 ID,id 是可能需要的 RFID/PIN,標誌如下:
'C':停用加載(需要管理員密碼或用戶 PIN/RFID)
'c':再次停用加載(需要管理員密碼或用戶 PIN/RFID)
'E': 停用 wallbox 的收費規則(需要管理員密碼)
'e':再次關閉wallbox的收費規則(需要管理員密碼)
'U':停用用戶收費規則(需要用戶 RFID/PIN)
'u':再次停用用戶的收費規則(需要用戶 RFID/PIN)
以這種方式設置的標誌會一直保留,直到汽車從 Wallbox 中拔出。mamps=ma
:用 ma mA 覆蓋(限制)充電電流。
設置模擬電能表:/cnf?cmd=soft_meter&dev_id=d&val=v
v(可選)是以 Wh/VAh 為單位設置的能量。如果 v 不存在,則只讀取計數器。 d 是 EVSE 的設備 ID。返回值是設置之前的舊計數器讀數。
您可以創建一個無法被計費管理器讀取的計數器(設備類型 'HTTP Input'),但可以使用 HTTP POST 或 GET 在外部指定其當前值:/cnf?cmd=set_ajax_meter&dev_id=x
x是在設備配置中看到的設備ID,例如M1 。
POST正文包含一個JSON對象,如下所示:
{ "model": string, "import_vah": number, "export_wh": number, "voltage": [v1, v2, v3], "current": [c1, c2, c3], "power_w": number "is_va": bool }
能量值以 Wh 為單位,電壓以 V 為單位,電流以 mA 為單位,功率以 W 為單位。 “model”是磁貼中顯示的模型字符串。
我們的一些用戶 (#diebestenuserderwelt) 使用 curl 工具為計數器提供數據,例如:curl -i -X POST -H 'Content-Type: application/json' -d '{ "model": "TestModell", "import_wh": 12345, "export_wh": 23456, "voltage": [231, 232, 233], "current": [10001, 10002, 10003] }' --user admin:1234abcd 'http://192.168.2.111/cnf?cmd=set_ajax_meter&dev_id=M3'
作為HTTP GET,請求是這樣寫的:http://192.168.2.111/cnf?cmd=set_ajax_meter&dev_id=M3&model=TestModell&import_wh=12345&export_wh=23456&voltage=231,232,233¤t=10001,10002,10003
這是使用 cFos HTTP 輸入儀表和 ioBroker 連接智能儀表的另一個論壇條目。
您還可以創建一個牆盒(設備類型'HTTP Input'),它不會被充電管理器讀取或控制,但可以使用 HTTP POST 或 GET 在外部指定其值。然後將控制值作為響應返回:/cnf?cmd=set_ajax_evse&dev_id=x
x是在設備配置中看到的設備ID,例如E1 。
POST正文包含一個JSON對象,如下所示:
{ "state": number, "max_charging_current": number, "current": [c1, c2, c3], "total_energy": number, "model": string, "rfid": string }
“模型”是模型字符串,如磁貼所示。借助“ rfid”,您可以在充電過程中添加RFID,能量值以Wh為單位,電流以mA為單位。 “狀態”具有以下值:
1 =等待(A), 2 =存在EV(B), 3 =充電(C), 4 =通風充電(D), 5 =錯誤(E)
作為一個 HTTP GET,請求是這樣寫的:http://192.168.2.111/cnf?cmd=set_ajax_evse&dev_id=M3&model=TestModell&state=st&max_charging_current=m¤t=c1,c2,c3&total_energy=t&rfid=r
作為響應,此請求返回以下JSON對象:
{ “ device_enabled”:true/false, //設備已啟用/禁用 “ charging_enabled”:正確/錯誤, //允許/不允許充電 “ paused”:true/false, // true =設備暫時暫停 “ charging_current”:數字//以mA為單位指定的充電電流 }
該返回對象必須由調用方評估,並且必須相應地設置EVSE,例如,必須相應地更改充電電流。
所有請求都會傳回 JSON 格式的回應。標記為r/o的值是唯讀的。請注意:我們不保證該API的穩定性。功能、參數、值等如有變更,恕不另行通知。

get_user取得單一使用者對象,
set_user POST 單一使用者對象,
get_users取得使用者物件數組
如果set_user包含有效的使用者 ID,則無需管理員密碼即可存取它。建立新使用者需要管理員權限
