Any open source platform should have a forum to discuss problems, suggestions, share ideas, and of course provide help. Just a few days ago I created a community forum for the thinger.io platform, so early adopters can get help when starting with the platform. I am creating some posts entries these days with the basic steps for installing the libraries, registering devices, and getting the devices connected. The community forum is at https://community.thinger.io.
I have shared in this forum a very simple IoT project that is a Plant Water Monitor that email me when a plant requires water, and also allows configuring remotely some parameters. It can be a good starting project that illustrates the use of the thinger.io platform.
Here is a picture of the setup with an NodeMCU (ESP8266).
