To enable the module in its full capacity, you need to create a yaml configuration script in ESPHome.

• nodemcu-ps4iot-v1.yaml - contains ESPHome node-side configuration script example

In addition, you must add a synthetic battery voltage rate sensor to the Home Assistant server's general 'configuration.yaml' configuration file:

• configuration.yaml - contains Home Assitant server-side configuration script example

The configuration must include the following entities:

• sensor.nodemcu_battery_voltage_level
• sensor.battery_voltage_change_per_hour
• binary_sensor.nodemcu_ps4iot_external_power_supply_detector
• switch.nodemcu_ps4iot_bat_charge_enable
• binary_sensor.nodemcu_ps4iot_red_charge_in_progress
• binary_sensor.nodemcu_ps4iot_blue_charge_completed

• sensor.battery_voltage_change_per_hour

• sensor.nodemcu_ps4iot_battery_level_text_state
• sensor.nodemcu_ps4iot_charge_text_state
• sensor.nodemcu_ps4iot_numeric_battery_level_value

1. Download .yaml example files
2. Under ESPHome plugin menu in your Home Assistant Server instance create new ESP8266 or ESP32 node.
3. Make all needed modifications and additions to your node's yaml-file.
4. Compile and use
5. Also you may add server-aided additional state sensors using configuration.yaml file as in examples.
