+* On-Time (Time in seconds device is switched on)
+
+
+## Prerequisites
+
+Before using Smart Plugs with openHAB the devices must be connected to the Wi-Fi network.
+This can be done using the Tapo provided mobile app.
+You need to setup a bridge (Cloud-Login) to commiunicate with your devices.
+
+## Discovery
+
+Discovery is done by connecting to the Tapo-Cloud Service. 
+All devices stored in your cloud account will be detected even if they are not in your network.
+You need to know the IP-Adress of your device. This must be set manually in the thing configuration
+
+## Bridge Configuration
+
+The bridge needs to be configured with by `username` and `password` (Tapo-Cloud login) .
+This is used for device discovery and to create a handshake (cookie) to act with your devices over the local network.
+
+The thing has the following configuration parameters:
+
+| Parameter          | Description                                                          |
+|--------------------|----------------------------------------------------------------------|
+| username           | Username (eMail) of your Tapo-Cloud                                  |
+| password           | Password of your Tapo-Cloud                                          |
+
+## Thing Configuration
+
+The thing needs to be configured with `ipAddress`.
+
+The thing has the following configuration parameters:
+
+| Parameter          | Description                                                          |
+|--------------------|----------------------------------------------------------------------|
+| ipAddress          | IP Address of the device.                                            |
+| pollingInterval    | Refresh interval in seconds. Optional. The default is 30 seconds     |
+
+
+## Channels
+
+All devices support some of the following channels:
+
+| group     | channel          |type                    | description                  | things supporting this channel  |
+|-----------|----------------- |------------------------|------------------------------|---------------------------------|
+| actuator  | output           | Switch                 | Power device on or off       | P100, P105,L510, L530, L900     |
+|           | brightness       | Dimmer                 | Brightness 0-100%            | L510, L530, L900                |
+|           | colorTemperature | Number                 | White-Color-Temp 2500-6500K  | L510, L530, L900                |
+|           | color            | Color                  | Color                        | L530, L900                       |
+| device    | wifiSignal       | system.signal-strength | WiFi-quality-level           | P100, P105, L510, L530, L900    |
+|           | onTime           | QuantityType <Time>    | seconds output is on         | P100, P105, L510, L530, L900    |
+
+
+## Channel Refresh
+
+When the thing receives a `RefreshType` command the thing will send a new refreshRequest over http.
+To minimize network traffic the default refresh-rate is set to 30 seconds. This can be reduced down to 10 seconds in advanced settings of the device. If any command was sent to a channel, it will do an immediately refresh of the whole device.
+
+
+## Full Example
+
+### tapocontrol.things:
+
+```
+tapocontrol:bridge:myTapoBridge                     "Cloud-Login"               [ username="you@yourpovider.com", password="verysecret" ]
+tapocontrol:P100:myTapoBridge:mySocket              "My-Socket"                 [ ipAddress="192.168.178.150", pollingInterval=30 ]
+tapocontrol:L510_Series:myTapoBridge:whiteBulb      "white-light"               [ ipAddress="192.168.178.151", pollingInterval=30 ]
+tapocontrol:L530_Series:myTapoBridge:colorBulb      "color-light"               [ ipAddress="192.168.178.152", pollingInterval=30 ]
+tapocontrol:L900:myTapoBridge:myLightStrip          "light-strip"               [ ipAddress="192.168.178.153", pollingInterval=30 ]
+``` 
+
+### tapocontrol.items:
+
+```
+Switch       TAPO_SOCKET      "socket"                { channel="tapocontrol:P100:myTapoBridge:mySocket:actuator#output" }
