Xiaomi IOT devices are supported. The following devices has been thoroughly tested:

• Gateway
• Door/window sensor
• PIR sensor
• Temperature/humidity

You can interact with the Xiaomi devices in 3 ways:

1. Read - Asking for a status, e.g. is the door open (door sensor)
2. Report - Awaiting an action, e.g. when the door opens, it sends a notification (door sensor)
3. Write - Send a message to the device (only some devices accepted this), e.g. play a sound (gateway)

All you Xiaomi devices are connected to a gateway. It is through this gateway, we are communicating with each of the devices. Each devices is identified with a SID. Before NimHA can use the Xiaomi devices, you need to setup the gateway and the devices with your Xiaomi app.

To write to a device, we need to exchange a encrypted key with the gateway based on a ever-changing token. We are currently using a Python script to generate the encrypted key from the token.

But before we can generate the key, you need to gather you gateway password. Follow this guide Domotics or the bullets below. Remember to write the key down.

1. Install the Xiaomi app
2. Set the region to Mainland China under Settings->Locale
3. You can set the language to English, even though the region is China
4. Sign in/Make an account
5. Select your Gateway in the app
6. Tap the 3 dots in top right corner
7. Click About
8. Tap on the version repeatedly until a new menu appear

Only devices that you can either read data from or devices their report status are allowed.

To continuously read a value each time it changes, you have to set the action to read. This will ensure, that the value will be displayed on your dashboard.

When reading a value, the "Value data" needs to be empty.

The report is primary used in conjunction with the alarm. When using the report, you also need to specify the "Value data" and the "Trigger alarm".

For PIR sensors the "Value name" would be status and the "Value data" would bed motion.

For magnet sensors the "Value name" would be status and the "Value data" would bed open or close.

Examples of possible values for "Value data":

• Read: PIR sensors will respond with motion
• Read: Magnet sensors will respond with voltage
• Read: Magnet sensors will respond with status for the switch
• Report: PIR sensors will respond with status
• Report: Magnet sensors will respond with status for the switch
