问题 I've been following the Gather, visualize, analyze and detect anomalies in IoT data tutorial and, although I was able to go through it flawlessly, I'm stuck in the second step of the "Create a data connector to store the historical data" section. In my Watson IoT left menu, there is no entry called "Extensions" , my last option is the "Configuration" one. As far as I know, I have re-checked all the steps twice and I have tried to configure different regions (I'm located in Spain) for both

问题 I'm trying to hook-up an Apache Spark Structured Stream to a MQTT topic (IBM Watson IoT Platform on IBM Bluemix in this case). I'm creating the structured stream as follows: val df = spark.readStream .format("org.apache.bahir.sql.streaming.mqtt.MQTTStreamSourceProvider") .option("username","<username>") .option("password","<password>") .option("clientId","a:vy0z2s:a-vy0z2s-zfzzckrnqf") .option("topic", "iot-2/type/WashingMachine/id/Washer02/evt/voltage/fmt/json") .load("tcp://vy0z2s.messaging

问题 I've been trying for a few days now to use Cloudant as my Watson IoT Platform´s Historian service, but still no success. I've finally managed to connect them with help I got here: Can't connect Watson IoT Platform to Cloudant, so I was able to set the bucket interval, and so on. But though I can see them as connected in each "Connections" tab, no databases were created, and I can´t see Cloudant when I'm setting up my board Card. When I get to the Extensions page on WIoTP and click on the gear

问题 I am using a Watson IOT Output (wiotp out) in a Node-RED flow on my Raspberry PI and am having issues with the connection repeatedly disconnecting and then re-connecting. Here is a screenshot of my Credentials Node and one of my IOT Out Node. The connection is configured so that I can send messages to the cloud and successfully have them trigger a flow in my cloud Node-RED instance. The problem I'm having is that when I attempt to send a string array as my payload, very items in the array

问题 I opened my Node RED flow editor from an existing instance of the Watson IoTP and saw a warning about unsupported version of Node.js. "Using an unsupported version of Node.js You should upgrade to the latest Node.js LTS release" How do I fix this ? 回答1: When a boilerplate application is created, it is a snapshot of the application boilerplate at that time. Unless you maintain it, nothing changes. The warning is indicating that the Node RED version itself has updated (and is now warning about

问题 I am experimenting with IoT services in IBM Bluemix, attending a running MOOC at Coursera. I have set up my trial account and successfully registered some devices. I am testing the connectivity between Bluemix and my Raspberry Pi with the following simple Node-RED flow in Bluemix: Node-RED flow @ Bluemix where normal and alert are simple injection nodes of the respective strings, the format message node is similarly simple (returns msg , where msg.payload = {'a' : {'indicator' : msg.payload}}

问题 I've been trying for some time now to connect my Watson IoT Platform to a Cloudant database as a Historian service. I´ve followed instructions from a variety of tutorials available but one service never appears as an possible connection to the other, or as an extension. Here is one tutorial that I've tried https://console.bluemix.net/docs/services/IoT/cloudant_connector.html#cloudant_main This is my resources dashboard. I've read that I should create both services in the same space (projetos

问题 Related to that question: My wiotp out node is on a RPi, the wiotp in node on IBM Cloud. They can connect to the platform using the same credentials, but only one of them is connected, disconnecting after some seconds and vice versa. What needs to be changed so both remain connected? 回答1: If your two clients are using the same MQTT clientId, then they will fight over the same connection. Could that be happening here? 来源： https://stackoverflow.com/questions/53886475/watson-iot-out-and-in-nodes

问题 I build the "anything else" node at the and of my dialog. When entering , just a dummy, weird text like "dsajhfkjhfajfk" then - all the time, it seems like Watson is by default choosing the semi last intend node... instead of going into the anything else node 回答1: It's best to understand that the intents is Watsons view of the world. As it tries to answer a question, it assumes that your question relates to how it sees the world. It doesn't know that dsahfkjshasdk is meaningless, because you
