Spark.Publish DHT11 Temp data...please help

[LukeUSMC]

Hello All. I have cobbled together various examples and libraries to get my DHT11 sensor to sample every 20 seconds and display the data on an I2C 128x64 OLED. So far so good but this is just the beginning of what I hope to build. I would like to start using Spark.Variable and Spark.Publish to keep track of values I getting from this sensor and the sensors to follow. All in all I will have the following running from my Spark Core (will switch to Photon when it arrives): 2 x Relays or PowerTail switches, Air/Humidity Sensor (switching to something more accurate than the DHT11 down the road), 128x64 OLED in I2C mode, One Wire waterproof sensor, a few RGB LEDs (NeoPixels) and a water PSI sensor (need help finding one if anyone has any ideas). Could someone look at my code and tell me how to capture the DHT.getFahrenheit as a Spark.Variable that can then be published?

Code is posted on my GitHub: https://github.com/LukeUSMC/Poolmation

Tutorial: Spark Variable and Function on One Web Page

Let’s say you have a Spark core with both a Spark variable and a Spark function. In my case, I have the world’s simplest servo control sketch, using the nice miniature servo in the Spark Maker Kit. Using these parts, we will build a servo that you can control from a web page anywhere and monitor the position of the servo too! Here’s a preview of the finished tutorial: [image] There is a coarse adjust slider, two fine adjust buttons, and the current position of the servo is displayed. That…

Multiple Cores Publishing to One Web Page

This is a mini-tutorial! Let’s say your have sensor farm of Spark cores all publishing their data to the Spark Cloud. You need a way to see all that data in near real-time, all on one dashboard. So, how can you do it? There are lots of ways but here’s a simple one that you can edit and change to meet your needs. First a couple of in action screen shots, first for the event named “Uptime”: [image] And here’s another shot for the event named “Temp”: [image] As you can see, you enter your…

A forum search should also point you toward several topics in which the same has been done. Do check those out, give it a try, and let us know if you can't figure it out
