+# Midea AC Binding
+
+This binding integrates Air Conditioners that use the Midea protocol. Midea is an OEM for many brands.
+
+An AC device is likely supported if it uses one of the following Android apps or it's iOS equivalent.
+
+| Application | Comment | Options |
+|--:-------------------------------------------|--:------------------------------------|--------------|
+| Midea Air (com.midea.aircondition.obm) | Full Support of key and token updates | Midea Air |
+| NetHome Plus (com.midea.aircondition) | Full Support of key and token updates | NetHome Plus |
+| SmartHome/MSmartHome (com.midea.ai.overseas) | Full Support of key and token updates | MSmartHome |
+
+Note: The Air Conditioner must already be set-up on the WiFi network and have a fixed IP Address with one of the three apps listed above for full discovery and key and token updates.
+
+## Supported Things
+
+This binding supports one Thing type `ac`.
+
+## Discovery
+
+Once the Air Conditioner is on the network (WiFi active) the other required parameters can be discovered automatically.
+An IP broadcast message is sent and every responding unit gets added to the Inbox.
+As an alternative use the python application msmart-ng from with the msmart-ng discover ipAddress option.
+
+## Binding Configuration
+
+No binding configuration is required.
+
+## Thing Configuration
+
+| Parameter | Required ? | Comment | Default |
+|--:----------|--:----------|--:----------------------------------------------------------------|---------|
+| ipAddress | Yes | IP Address of the device. | |
+| ipPort | Yes | IP port of the device | 6444 |
+| deviceId | Yes | ID of the device. Leave 0 to do ID discovery (length 6 bytes). | 0 |
+| cloud | Yes for V.3 | Cloud Provider name for email and password | |
+| email | No | Email for cloud account chosen in Cloud Provider. | |
+| password | No | Password for cloud account chosen in Cloud Provider. | |
+| token | Yes for V.3 | Secret Token (length 128 HEX) | |
+| key | Yes for V.3 | Secret Key (length 64 HEX) | |
+| pollingTime | Yes | Polling time in seconds. Minimum time is 30 seconds. | 60 |
+| timeout | Yes | Connecting timeout. Minimum time is 2 second, maximum 10 seconds. | 4 |
+| promptTone | Yes | "Ding" tone when command is received and executed. | False |
+| version | Yes | Version 3 has token, key and cloud requirements. | 0 |
+
+## Channels
+
+Following channels are available:
+
+| Channel | Type | Description | Read only | Advanced |

+## Examples
+
+### `demo.things` Example
+
+```java
+Thing mideaac:ac:mideaac "myAC" @ "Room" [ ipAddress="192.168.1.200", ipPort="6444", deviceId="deviceId", cloud="your cloud (e.g NetHome Plus)", email="yourclouduser@email.com", password="yourcloudpassword", token="token", key ="key", pollingTime = 60, timeout=4, promptTone="false", version="3"]

+
+Option to use the built-in binding discovery of ipPort, deviceId, token and key.
+
+```java
+Thing mideaac:ac:mideaac "myAC" @ "Room" [ ipAddress="192.168.1.200", ipPort="", deviceId="", cloud="your cloud (e.g NetHome Plus)", email="yourclouduser@email.com", password="yourcloudpassword", token="", key ="", pollingTime = 60, timeout=4, promptTone="false", version="3"]
+```
+
+### `demo.items` Example
+
+```java
+Switch power "Power" { channel="mideaac:ac:mideaac:power" }
+Number:Temperature target_temperature "Target Temperature [%.1f °F]" { channel="mideaac:ac:mideaac:target-temperature" }
+String operational_mode "Operational Mode" { channel="mideaac:ac:mideaac:operational-mode" }
+String fan_speed "Fan Speed" { channel="mideaac:ac:mideaac:fan-speed" }
+String swing_mode "Swing Mode" { channel="mideaac:ac:mideaac:swing-mode" }
+Number:Temperature indoor_temperature "Indoor Temperature [%.1f °F]" { channel="mideaac:ac:mideaac:indoor-temperature" }
+Number:Temperature outdoor_temperature "Current Temperature [%.1f °F]" { channel="mideaac:ac:mideaac:outdoor-temperature" }
+Switch eco_mode "Eco Mode" { channel="mideaac:ac:mideaac:eco-mode" }
+Switch turbo_mode "Turbo Mode" { channel="mideaac:ac:mideaac:turbo-mode" }
+Switch sleep_function "Sleep function" { channel="mideaac:ac:mideaac:sleep-function" }
+Switch temperature_unit "Fahrenheit or Celsius" { channel="mideaac:ac:mideaac:temperature-unit" }
+```
+
+### `demo.sitemap` Example
+
+```java
+sitemap midea label="Split AC MBR"{
+ Frame label="AC Unit" {
+ Text item=outdoor_temperature label="Outdoor Temperature [%.1f °F]"
