What's in example files

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

Node-side (ESPHome plugin node config) entities:

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

Server-side (Home Assistant general config) entities:

sensor.battery_voltage_change_per_hour

Additional server-sided text state sensors:

sensor.nodemcu_ps4iot_battery_level_text_state
sensor.nodemcu_ps4iot_charge_text_state
sensor.nodemcu_ps4iot_numeric_battery_level_value

Install

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