Hi guys,

@adam created a great tutorial for adding the DHT11 / 22 sensor to the Cayenne dashboard using the Cayenne MQTT API. I realize this is probably not what you had in mind, but you can now read data from your DHT11 sensors, and send the values to Cayenne from the Raspberry Pi! I’m hoping you will give it a try, here is the post you can reference:

DHT11/DHT22 with Raspberry Pi

About This Project This project will read temperature and humidity from a DHT11 or DHT22 sensor and send the values to Cayenne using MQTT. The python MQTT client and Adafruit DHT sensor library will need to be installed for this script to run. Install the software prerequisites using the commands below: sudo pip install paho-mqtt sudo apt-get install build-essential python-dev python-openssl git clone https://github.com/adafruit/Adafruit_Python_DHT.git cd Adafruit_Python_DHT sudo python …
