+
+## Flash ESPHome
+
+Flashing the device can be done in 2 different ways.
+
+### 1. Upload .bin file (using original firmware)(easiest)
+
+The original firmware comes with the option to upload a custom .bin file.
+This can be done by connecting to the device's access point over Wi-Fi.
+Open a browser and navigate to the IP address displayed on the screen of the device.
+Find the "Firmware update" section in the web interface and upload your .bin file.
+The .bin file can be generated with ESPHome Device Builder using the correct config below.
+
+### 2. Manual flashing via Serial (Disassembly needed)
+
+If the first option is not usable for you, you can always flash the device manually by disassembling it first.
+Unscrew the 2 screws at the bottom of the device and slide the plastic casing open from the back of the device.
+Because this device doesn't have a USB to serial chip, we need to connect some wires to it in order to flash it.
