This firmware has been developed to send only important notifications for the irrigation and battery status, maximum attention to energy saving.
I used pushbullet excellent platform to send and receive notifications. Ppossible to have a free or premium account at a very low cost. Visit https://www.pushbullet.com/
the device sends messages only when necessary according to the configuration thresholds.
You need to use pushbullet app,available for different platforms
Find Lifely Agrumino Lemon (REV4 AND REV5) in www.lifely.cc */
