Esphome crashes on a Shelly Plug S

Hey there,

i want to flash a Shelly Plug S with esphome. So far so easy. I have found the followoing template and pinout: Esphome Devices - Shelly Plug S and compiled it to this easy sketch:

substitutions:
    ip: 10.0.3.33
    node_name: schlafzimmer_fernseher

esphome:
  build_path: ./build/${node_name}
  name: ${node_name}
  platform: ESP8266
  board: esp8285
  arduino_version: 2.4.2

wifi:
  ssid: TE-IOT
  password: !secret wifi_password
  manual_ip:
    static_ip: ${ip}
    gateway: 10.0.3.1
    subnet: 255.255.255.0

api:
  password: !secret api_password

logger:

ota:
  password: !secret ota_password

status_led:
  pin:
    number: GPIO2
    inverted: True

binary_sensor:
  - platform: gpio
    id: "Button"
    pin:
      number: GPIO13
      mode: INPUT_PULLUP
      inverted: True
    internal: true
    on_press:
      then:
        switch.toggle: relay

output:
  - platform: gpio
    pin: GPIO00
    inverted: true
    id: led

switch:
  - platform: gpio
    pin: GPIO15
    id: relay
    name: "Schlafzimmer Fernseher"
    on_turn_on:
      - output.turn_on: led
    on_turn_off:
      - output.turn_off: led 

and uploaded it to the Plug S without any problems. After the first reset the esp is stuck in a boot loop and just spits out a stack trace:

I already have recompiled and reflashed it but it does not change anything.
Does anyone has an idea?
