Sigfox to Cayenne


#1

I send temperature and humidity from DHT11 to Sigfox.
Node Red will download the data from Sigfox Backend and send it via MQTT to Cayenne.

You need it:

  • Arduino Mega (or Arduino UNO and SoftwareSerial for modem)
  • Sigfox modem Wisol SFM10R1
  • DHT11 Temperature and Humidity sensor
  • Level shifter
  • Raspberry Pi with Node Red

Arduino Code

Cayenne-Sigfox-DHT11.txt (1.5 KB)

When you enter 1 to the serial monitor, send the data to Sigfox Backend.

Node red flows

Using Sigfox device with Cayenne
Anyone linked SigFox with Cayenne?

I probably should update that a bit to include the Cayenne MQTT libraries instead of generic ones, but thanks for the link.

Thanks for sharing @tad.dvor ! I think this is first Sigfox project I’ve seen posted :slight_smile:

And, yeah good point @adam, whenever you have some free time.

how about news for this update ? we are some people wanting to import sigfox data directly into cayenne without intermediaries (like node red)?
