\nCharge your Android device in clever way – let it drive its charging process by itself. Charging cable is wired though IoT AC relay. App sends commands to relay wireless via MQTT protocol. Once charged relay gets OFF and vice versa.<\/p>\n

\n– IoT relay payloads – to control relay – refer to Tahoma FW<\/p>\n
\nCode subcribes to MQTT and based on payloads („ON“ or „OFF“) turns GPIO 4 at pin 7 low or high. Connect AC relay to this pin and there you go.<\/p>\n","protected":false},"excerpt":{"rendered":"
