Obtaining RK3066 boot ROM.

Here are my steps.

At first, I took a look to RK30xxLoader(L)_V1.18.bin. This file appears in update.img for my device. So, I unpacked update.img using rk29Kitchen.

strings on that file returns nothing interesting, so I assumed the file is crypted

⚠️ There is now an official way to connect Glow to Home Assistant via MQTT, I would suggest using that instead of the method described below. Here are the sensor templates for that (replace GLOW_DEVICE_ID with the relevant information for your device):

mqtt:
  sensor:
    - name: "Home Power"
      state_topic: "glow/GLOW_DEVICE_ID/SENSOR/electricitymeter"
      unit_of_measurement: 'W'
      value_template: "{{ (value_json['electricitymeter']['power']['value'] * 1000) | int }}"
      icon: 'mdi:flash'
