Switching from Tasmota to ESPHome

By default this device comes with Tasmota firmware. To flash ESPHome, follow these steps:

1. Create a secrets.yaml file based on the secrets.yaml.example file and fill in your WiFi credentials.

wifi_ssid: "your-wifi-ssid"
wifi_password: "your-wifi-password"
wifi_ap_password: "esphome"

2. Run make compress to compile the firmware and compress it using gzip.

   Without compression, the firmware will not fit on the device and you will get a “Not enough space” error.

3. Open the Tasmota web interface and upload the compressed firmware (firmware.bin.gz) to the device.

   If you still run into issues, try flashing the Tasmota minimal firmware first, restart and then flash the ESPHome firmware.

   !WARNING Do not upgrade from a Tasmota minimal to minimal version. It will most likely fail at some point and will require flashing via serial.

The device will reboot and connect to your WiFi network, and should be auto-detected in Home Assistant.
