+## The [GryfSmart](https://gryfsmart.pl) integration for home assistant allows you to connect to GryfSmart devices
+
+This document describes how to configure and use the GryfSmart integration. The integration support Config Flow (UI-based setup), and requires RS232 interface.
+
+There is currently support for the following device types within Home Assistant:
+
+ - Light
+ - Switch
+ - Thermostat
+ - Binary Input
+ - PWM
+ - Termometer
+ - Input
+

+## 1. Important Integration Information
+
+### 1.1 How to Use the ID
+
+The ID is a combination of the driver ID and the cell number (for outputs,
+inputs, etc.).
+
+17
+
+- 1 is the driver ID
+- 7 is the cell number
+
+### 1.2 Communication
+
+To connect gryfsmart, you can use either a Physical RS-232 connection or a
+USB/RS-232 converter. You need to know the address of the device. Typically, it
+is "/dev/ttyS0" for a physical RS-232 port, or "/dev/ttyUSB0" for a converter.
+
+### 1.3 Module Count
+
+The module count is the number of modules in the network.
+
+### 1.4 Entities
+
+{% note %}
+
+**gryfsmart driver supports 5 types of functions:**
+
+- **Relay Output (O)**
+- **Input (I)**
+- **PWM**
+- **Temperature Input (T)**
+- **Cover Output(S)**
+
+{% endnote %}
+
+#### 1.4.1 Light
+
+- **Type of function:** Relay Output
+- **Services:** turn_on, turn_off
+- **Icon:** lightbulb
+- **Entity type:** light
+- **Configuration scheme:** classic
+- **Device class:** None
+
+#### 1.4.2 Switch
+
+- **Type of function:** Relay Output
+- **Services:** turn_on, turn_off, toggle
+- **Icon:** switch, outlet
+- **Entity type:** switch
+- **Device class:** switch, outlet
+- **Default device class:** switch
+
+#### 1.4.3 Thermostat
+
+- **Type of function:** Relay Output and Temperature Input
+- **Services:** turn_on, turn_off, toggle, set_temperature
+- **Entity type:** climate
+In Config Flow, you enter the t_id into the "extra" parameter
+and the o_id into the "id" parameter.
+
+- **Device class:** None
+
+#### 1.4.4 Binary Input
+
+- **Type of function:** Input
+- **Services:** None
+- **Icon:** Specific for the chosen device class
+- **Entity type:** binary_sensor
+- **Device class:** door, garage_door, heat, light, motion,
+window, smoke, sound, power
+- **Default device class:** opening
+
+#### 1.4.5 PWM
+
+- **Type of function:** PWM
+- **Services:** turn_on, turn_off, toggle, set_value
+- **Icon:** lightbulb
+- **Entity type:** light
+- **Device class:** None
+
+#### 1.4.6 Thermometer
+
+- **Type of function:** Temperature Input
+- **Services:** None
+- **Icon:** thermometer
+- **Entity type:** sensor
+- **Device class:** None
+
+#### 1.4.7 Input
+
+- **Type of function:** Input
+- **Services:** None
+- **Icon:** switch
+- **Entity type:** sensor
+- **Device class:** None
+- **Extra information:**  
+  If the input is a short press and release, the sensor state is 2;
+if it is a long press, the state is 3.
+
+
+
+## 2. Configuration via Config Flow
+
+The "extra" parameter corresponds to the device_class if it exists. In the case
+of a thermostat, the "extra" parameter maps to **t_id** instead. Otherwise, this
+parameter is not required. Additionally, the integration supports editing of
+individual devices and configuration. Please note that after making changes,
+you must reload the integration for the changes to take effect.
+
+## 4. Helper Entities
+
+Additionally, the configuration automatically generates two entities—**gryf_in**
+and **gryf_out**. The **gryf_in** entity receives incoming messages, and the
+**gryf_out** entity handles outgoing messages. However, if you are not an
+experienced GRYF SMART installer, you may ignore these details.
