I have an application running on ESP8266, and a local server on Raspberry Pi.
I also have the possibility of sending Whatsapp messages from the raspberry using yowsup.
I would like to get whatsapp notifications on certain conditions happening on the ESP8266 hardware.
So the question is:
Is it easily possible to retrieve the status of the hardware from the server itself? In that case, I could have a script on the Raspberry to trigger the whatsapp notification.
