Blynk and Node Red

Need Help With My Project

Hi Blynkies,

I tried to implement a connection between the TI CC2650 sensortag via Node Red into Blynk for visualization. When I configure the URL in Node Red (node-red-contrib-blynk-websockets 0.0.3)
URL = ws://cloud.blynk.cc:8082/ws the key param contains the Auth token, I get in the Node Red log:

any ideas whats wrong with the URL ?

Thanks in advance

Hi Dimitriy,

no change :frowning:
Is there a way to check that URL from my Raspi ? (command line … ?)
Thanks Peter

Btw: Do you have an idea why Node Red why the blynk node in the node red server logs says: errors.missing-conf.
Thanks Peter

I was testing out the functionality between Blynk and Node RED… I have a esp8266 with temp sensor on Blink and a cc3200 with temp sensor on Node RED. I can send the temp data from Node RED to the Blynk App, (no problem). I can read the vertical pin data (buttons, sliders, etc.) from the Blynk App in Node RED (no problem). But I cannot read the esp8266 temp sensor, virtual pin “V6”, tempData “Blynk.virtualWrite(V6, tempData);” from the Blynk server in Node RED.

Is this just the functionality between Blynk and Node RED at this time or am I doing something wrong?
