HTTP的应用程序编程接口(API)

以下函数提供了Modbus寄存器与HTTP的映射。
注意:使用HTTP API时,Modbus不需要激活。

使用HTTP GET或POST请求到cFos收费控制器的地址,例如:
http://192.168.2.111/cnf?cmd=modbus&device=meter1&read=35154。
响应为JSON格式。

  • cmd总是modbus
  • 设备=meter1meter2evse
  • read= 要读取的寄存器的地址
  • = 要读的寄存器的地址
  • =要写的值
  • values= 要写的数值数组,例如[1,2,3,4]

地址可以有一个后缀来指定数据类型(默认是16位整数)。

  • d= 32位整数(2个modbus寄存器)。
  • q= 64位整数(4个modbus寄存器)。
  • s=字符串

一般要求

要求所有充电管理器设备的状态。
/cnf?cmd=get_dev_info

设置一个PIN码或RFID。
/cnf?cmd=enter_rfid&rfid=r&dev_id=d
r是PIN或RFID(数字),d是可选的设备ID,用于选择特定的EVSE。如果没有选择设备ID,充电管理器将尝试自动分配PIN或RFID。

覆盖当前交易。
/cnf?cmd=override_device&dev_id=d&flags=f&mamps=ma&rfid=id
d是设备ID,id是可能需要的RFID/PIN,标志,如下:
'C':禁用充电(需要管理员pwd或用户PIN/RFID)
'c':再次禁用充电(需要管理员权限或用户PIN/RFID)
'E':禁用EVSE充电规则(需要管理员pwd)
'e':再次禁用EVSE充电规则(需要管理员pwd)
'U':停用用户的充电规则(需要用户的RFID/PIN)
'u':再次停用用户的充电规则(需要用户的RFID/PIN)

以这种方式设置的标志保持到汽车从EVSE上拔下插头。

mamps=ma:用ma mA覆盖(限制)充电电流。

设置模拟的能量表。
/cnf?cmd=soft_meter&dev_id=d&val=v
v(可选)是要设置的能量,单位是Wh/VAh。如果v不存在,只读取电表。d是EVSE的设备ID。返回值是设置前的旧电表读数。

HTTP电表和EVSE

仪表

你可以创建一个仪表(设备类型为 "HTTP输入"),它不被计费管理器读取,但其当前值可以通过HTTP POST或GET从外部指定。
/cnf?cmd=set_ajax_meter&dev_id=x
x是设备配置中看到的设备ID,例如M1

POST主体包含一个JSON对象,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
         }

这里,能量值的单位是Wh,电压的单位是V,电流的单位是mA,功率的单位是W。"model "是瓷砖中所示的模型串。

我们的一些用户(#diebestenuserderwelt)使用curl工具为仪表提供数据,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'

作为HTTP GET的请求是这样写的:
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&current=10001,10002,10003

这里是另一个关于使用cFos HTTP输入和ioBroker连接智能表的论坛帖子。

EVSE

你也可以创建一个墙盒(设备类型 "HTTP输入"),它不被充电管理器读取或控制,但其值可以使用HTTP POST或GET从外部指定。然后,控制值被作为响应返回。
/cnf?cmd=set_ajax_evse&dev_id=x
x是设备配置中看到的设备ID,例如E1

POST主体包含一个JSON对象,如下所示。

{
            "state": number,
            "max_charging_current": number,
            "current": [c1, c2, c3],
            "total_energy": number,
            "model": string,
            "rfid": string
         }

"model "是模型字符串,如瓷砖中所示。通过 "rfid",你可以在充电过程中添加一个RFID,能量值以Wh为单位,电流以mA为单位。"state "有以下值。
1=等待(A),2=电动车存在(B),3=充电(C),4=通风充电(D),5=错误(E)。

作为HTTP GET的请求是这样写的:
http://192.168.2.111/cnf?cmd=set_ajax_evse&dev_id=M3&model=TestModell&state=st&max_charging_current=m&current=c1,c2,c3&total_energy=t&rfid=r

作为回应,该请求返回以下JSON对象。

{
            "device_enabled": true/false, // 设备已启用/禁用
            "charge_enabled": true/false, // 允许/不允许充电
            "paused": true/false, // true = 设备暂时暂停使用
            "charging_current": number // 指定的充电电流,单位为mA
         }

这个返回对象必须由调用者进行评估,并且EVSE必须进行相应的设置,例如,充电电流必须进行相应的改变。

网络界面

所有请求都会以 JSON 格式返回响应。标有 r/o 的值为只读值。请注意:我们不保证此 API 的稳定性。功能、参数、值等如有变更,恕不另行通知。
