ThingsBoard物联网网关没有'；t更新MQTT值

我尝试使用IoT网关从外部MQTT代理主题接收简单的文本值

为此，我简化了现有脚本（

extensions/mqtt/custom_mqtt_uplink_converter.py

）：

当我启动gateway时，我在他的日志中看到他成功连接并读取了以下值：

INFO ... MQTT Broker Connector connected to 10.1.1.2:1883 - successfully.'
DEBUG ... Client <paho.mqtt.client.Client object at 0x7fb42d19dd68>, userdata None, flags {'session present': 0}, extra_params ()'

DEBUG ... <module 'CustomMqttUplinkConverter' from '/var/lib/thingsboard_gateway/extensions/mqtt/custom_mqtt_uplink_converter.py'>'
DEBUG ... Import CustomMqttUplinkConverter from /var/lib/thingsboard_gateway/extensions/mqtt.'
DEBUG ... Converter CustomMqttUplinkConverter for topic /devices/buzzer/controls/volume - found!'
INFO ... Connector "MQTT Broker Connector" subscribe to /devices/buzzer/controls/volume'
DEBUG ... Received data: {}'
DEBUG ... (None,)'
INFO ... "MQTT Broker Connector" subscription success to topic /devices/buzzer/controls/volume, subscription message id = 1'
DEBUG ... New data received: /devices/buzzer/controls/volume: 66'
DEBUG ... Result: {'deviceName': 'buzzer', 'deviceType': 'buzzer', 'telemetry': {'data': 66}}'

信息。。。MQTT代理连接器已成功连接到10.1.1.2:1883。'
调试。。。客户端，userdata None，标志{'session present'：0}，额外参数（）'
调试…'
调试。。。从/var/lib/thingsboard_gateway/extensions/mqtt导入CustomMqttUplinkConverter。'
调试。。。Converter CustomMqttUplinkConverter用于主题/设备/蜂鸣器/控件/音量-找到！'
信息。。。连接器“MQTT代理连接器”订阅/devices/buzzer/controls/volume'
调试。。。收到的数据：{}'
调试。。。（没有，）'
信息。。。“MQTT Broker Connector”对主题/设备/蜂鸣器/控件/卷的订阅成功，订阅消息id=1'
调试。。。接收到的新数据：/devices/蜂鸣器/控件/音量：66'
调试。。。结果：{'deviceName'：'buzzer'，'deviceType'：'buzzer'，'telemetry'：{'data'：66}'

但这个值是他能读到的最后一个值。如果我更改

volume

one代理，则新值既不会出现在日志中，也不会出现在TB UI中。（我用

mosquitto\u sub

控制更新）

在网关重新启动之前，此转换器似乎不会再次调用。你的行为正确吗

如果看不到结果，如何确保我的代码是正确的？

您好，我已经尝试了您的自定义转换器版本，它不起作用，但当我更改时

self.dict_结果[“遥测”]={“数据”：body}

到

self.dict_结果[“遥测”]=[{“数据”：body}]

它正确地发送了数据

---

网关需要一组来自转换器的属性遥测。

太棒了！但我在删除的代码中看到了这一点：

self.dict_result[“telemetry”]=“telemetry数组的模板”

。Спасибо, Илья!杰出的但我在删除的代码中看到了这一点：
