I’ve got a Lora node that sends a temperature reading to The Things Network (TTN). From TTN I’ve got a Webhook integration that sends the value to Blynk via the API service (http://blynk-cloud.com/TOKEN/update/V3?value= {{Value1}}) by means of IFTTT. The value is displayed on my Blynk project as a normal value display and works well. I would like to however use the superchart widget, but it is not working (only saying “No data yet…” even after the value display updated a few times). I’ve got the superchart linked to V3 pin. As far as I can figure out it has to do with the fact that I am working via the API only and not running an app on a controller with a timer, but I might be wrong. Any suggestions / help will be greatly appreciated.
So I managed to get this sorted by means of a few suggestions on various posts. If anyone has got the same issue here are the steps to get this going:
- Find your blynk-cloud IP address by typing ping http://blynk-cloud.com into command line.
- Use this IP address in the HTTP GET http://add ip here/TOKEN/update/V3?value= {{Value1}})
- You have to have a MCU that has got blynk running linked to the project, however it does not have to be physically linked to the actual node.
