I've made a power monitoring system by using 3 slave nodemcu to collect current reading using ACS712 and send it to master nodemcu. The master nodemcu should send data to phone to view the data through a mobile application. I used Thingspeak at first to view data of the power consumption but i want to use google firebase to view the power consumption easier for my application view. Any help?
