The GUI web server will be the last piece to develop, when I'll have all sensors/nodes in place. For now you can see the mobile app that I've developed for controling thinkgs around the house here: http://myesp8266.blogspot.ro/2015/10/update-android-application-to-control.htmlCatalin B.https://www.blogger.com/profile/05005510951764417065noreply@blogger.comtag:blogger.com,1999:blog-5163165289293853070.post-90426832153746472462015-12-02T17:37:50.330+02:002015-12-02T17:37:50.330+02:00Thanks Catalin.

They offer a free plan for 100 devices and 1 million messages a month. I just hesitate to refactor too many parts of my project at the same time. Current approach is to move away from a centralized Arduino Due into a more distributed ESP8266 model for collecting data closer to the sensor. (Ultimately MQTT makes very good sense in this model too.)<br /><br />Was Mosquito simple install on the Pi, or was there an SD card image with the broker already included? I am okay with Linux, but not super deep, so it could turn into a project of it's own... <br /><br />Regarding a GUI - Have you considered standing up a website to present and interact with your data? I am currently working to replace ThingSpeak with a Rails app that exposes API end points for the ESP to upload data, while also providing a GUI to display and interact with the data. A rather straight forward use case for Rails - but early work in progress for me. In the end I can envision the ability to manage devices, calibrations, and analytics in this app layer.<br /><br />Curious what you are doing regarding the GUI? Is it all mobile?<br /><br />Thanks!<br /><br />Jayjephttps://www.blogger.com/profile/08903302797848884148noreply@blogger.comtag:blogger.com,1999:blog-5163165289293853070.post-48335081740940076782015-12-02T08:13:50.993+02:002015-12-02T08:13:50.993+02:00Hi Jay,

In this way when I am away my mobile app is connecting to the cloud mqtt instance and when I am at home is using the raspberry pi's instance.Catalin B.https://www.blogger.com/profile/05005510951764417065noreply@blogger.comtag:blogger.com,1999:blog-5163165289293853070.post-44911678748051913192015-12-02T06:54:17.065+02:002015-12-02T06:54:17.065+02:00Great article and code, thanks for sharing.
Wou...Great article and code, thanks for sharing. <br /><br />Would you mind elaborating more around your mqtt configuration? The charts look like ThingSpeak, which I am using successfully. But your code seems to be using mqtt messages. I am not aware of an mqtt interface into ThingSpeak - am I simply not seeing it? <br /><br />Would love to get away from the REST interface and onto messaging... Any insights on your cloud mqtt service and how you are using it would be appreciated!<br /><br />Thanks,<br /><br />Jay<br /> jephttps://www.blogger.com/profile/08903302797848884148noreply@blogger.comtag:blogger.com,1999:blog-5163165289293853070.post-91464775289396329032015-11-27T16:29:23.931+02:002015-11-27T16:29:23.931+02:00Hi Thanks, I was using the latest version not 1.0....Hi Thanks, I was using the latest version not 1.0.

I've tried the adafruit with this one and the latest version automatically calculates the timings of the data stream and the temp values are too high and the humidity varies wildly. I think it calculating the data stream timings incorrectly in my case, I notice you can set the timing constant to 11, is this an older version or another library? Thanks.
