+A installation of ESPHome Flasher is required to flash the firmware to the ESP32.
+The ESP32 should be connected via USB.
+The software and install can be found here: https://github.com/esphome/ESPHome-Flasher
+Alternatively the arch package can be built: https://aur.archlinux.org/packages/esphome-flasher
+Run in terminal:
+<code> sudo esphomeflasher</code>
+Chose the binary file / firmware and click Flash ESP\\

+When the process was sucessfull, the ESP32 will connect to the wifi and the ESPHome integration and will show as online. From there on easy OverTheAir updates can be sent to this node.\\

 ==== 4. Discussion ====
 The system is not finalized and needs to expanded to work independantly of human input or observation.
+The relay module is not added to ESPHome yet, but integration is simple.
+The Gafana plot can be added to the Home Assistant dashboard for an easier overview of the current and past soil moisture values.
 The automations and deciscion making algorithms need to be refined and expanded to ensure proper working autonomous farm operation.
 There are already prebuilt systems for farming management or IoT cloud but building our own system from freely available software has given many insights on how the IoT infrastructure works and how to connect multiple devices to a central instance.\\
