I recently brought my first sensor working with the cloud service. This weekend i installed the local server on a raspi and reflashed the esp with the server-based sketch.
It took me a short while to realise that the sketch uses the virtual driver but then i configured a group and a node (temperature AI) in the virtual driver.
The sensor works as expected and sends updates regularly. They are shown with correct value in the node-view.
But the graph only shows the last value correct, all others are plotted out as zero. I took a look into the database and also there the values are wrong. If i compare them with the log entries they are totally different.
All works perfect. You want add virtual module. Then write module nbr to sketch. Sample N2S0. Upload to ESP. Then create group. I creat ESP + DS18b20 and add this virutual module N2S0 to this created group. Port in sketch is 80 not other. Thats all. Questions?
I try this with ESP-12F.
