+# ESPHome support for Xiaomi Mijia Bedside Lamp 2
+
+[ [Changelog](CHANGELOG.md) | [License](LICENSE.md) | [Code of conduct](CODE_OF_CONDUCT.md) ]
+
+The Bedside Lamp 2 is a smart RGBWW LED lamp, produced by Yeelight for the Xiaomi Mijia brand. It
+can be controlled via the WiFi network and from a touch panel on the front of the device. The touch
+panel contains a power button, a button that changes the color of the light and a slider that can be
+used to change the brightness of the light.
+
+This project provides custom components for ESPHome, which make it possible to fully control every
+aspect of the lamp and to integrate the lamp in your Home Assistant setup.
+
+## Features
+
+* The lamp **integrates easily with Home Assistant** using the ESPHome integration.
+
+* **The lamp no longer phones home to the Mijia Cloud.** Using this firmware, you can rest assured
+  that the network traffic is limited to your own network.  This matches the ideas behind Home
+  Assistant, of providing a local home automation platform, that puts privacy first.
+
+* **No more need for the LAN control option** to integrate the lamp with Home Assistant. Especially
+  important, because Xiaomi decided in all their wisdom to remove LAN control from the device,
+  breaking existing integrations.
+
+* **The night light supports multiple colors**. The original firmware only supports a single warm
+  white night light color.
+
+* **Smooth light color transitions**, unlike the current version of the Yeelight integration. The
+  Homekit integration does provide good transitions, but on my system, the color temperature white
+  light mode is missing in the Home Assistant GUI.
+
+* **Since the components of the lamp are exposed as ESPHome components, you don't have to stick with
+  the lamp's original behavior.** You can hook up the lamp in your home automation as you see fit.
+  Use the slider to control the volume of your audio set? Long press the power button to put your
+  house in night mode? Use the illumination behind the slider bar to represent the progress of your
+  sour dough bread bulk fermentation?  Go ahead, make it so! :-)
+
+* **All LEDs that are used for illumination of the front panel (power button, color button and
+  10 LEDs for the brightness slider) can be controlled individually.** This means that you have
+  12 LEDs in total to use as you see fit, instead of sticking with the behavior of the original
+  firmware.
+
+* **Possibilities to extend the device's functionality through hardware mods.** There are [GPIO pins
+  that are not in use](doc/technical_details.md#esp32-pinout).  If "tinkerer" is your middle name,
+  you can use those pins to come up with your own hardware hacks to extend the device's
+  functionality. 
+
+## Quick start guide
+
+For those who have experience with flashing ESPHome onto devices:
+
+* Make sure you are using ESPHome 2021.10.0 or newer.
+* Copy [`example.yaml`](example.yaml) to `<CONFIG_DIR>/<NODE_NAME>.yaml`.
+* Modify the configuration to your needs (see the [configuration guide](doc/configuration.md)).
+* Compile the `firmware.bin` file and download it to the device to which you have connected your
+  serial to USB adapter.
+* [Open up the lamp](doc/flashing.md#opening-the-lamp-to-expose-the-pcb) and connect its `TX`, `RX`,
+  `GND` and `GPIO0` debug pads to the serial adapter. Check this [image for the debug pad
+  locations](doc/images/09_debug_pads_for_soldering.jpg).
+* Power up the lamp with `GPIO0` connected to GND to enable flashing mode.
+* Flash `firmware.bin` onto the device, for example using
+  [esphome-flasher](https://github.com/esphome/esphome-flasher)..
+  
+## Upgrading
+
+I always try to make it possible to upgrade the lamp firmware without having to do anything special.
+Sometimes, this is not possible. For those cases, the upgrade instruction can be found here:
