Template for Low Power Device sending data over WiFi with MQTT
That template is designed for ESP8266 devices and allows to: -Connect to Network and MQTT broker -Send Data over MQTT -Deep Sleep (With saving Data and last error to RTC memory) Note: Deep sleep state provides power consumption on about 20uA -Read RTC memory which can be used to restore last state before Deep Sleep was used
05.09.2020 - Project has been put on hold - Because of long time to establish WiFi connection after deepSleep (required for low current usage). Will wait for decision after test with Bluetooth Low Energy.
