 9 | This is a [Homebridge](https://github.com/nfarina/homebridge) plugin for exposing the Xiaomi Flower Care / Flower Mate / Flower Monitor / Mi Flora devices to HomeKit. Historical display of temperature / moisture data is available via HomeKit apps that support graphing (e.g. Elgato Eve).

14 | ## Installation
15 | 
16 | ### Prerequisites
17 | 
18 | #### System dependencies
19 | 
20 | This plugin is using [node-mi-flora](https://github.com/demirhanaydin/node-mi-flora) / [Noble](https://github.com/noble/noble) in the background with the same package dependencies. You can install these dependencies using `apt-get`, if not already done.
21 | 
22 | ```
23 | (sudo) apt-get install bluetooth bluez libbluetooth-dev libudev-dev
24 | ```
25 | 
26 | For more details and descriptions for other platforms see the [Noble documentation](https://github.com/noble/noble#readme).
27 | 
28 | #### MAC address
29 | 
30 | Ensure you know the MAC address of your Xiaomi Flower Care. You can use `hcitool lescan` to scan for devices. The device will appear as `AA:BB:CC:DD:EE:FF Flower care` in the list.
31 | 
32 | ### npm
33 | 
34 | ```
35 | (sudo) npm install -g --unsafe-perm homebridge-mi-flower-care
36 | ```
37 | 
38 | ## Example Configuration
39 | 
40 | ```
41 | {
42 |   "accessory": "mi-flower-care",
43 |   "name": "Golden cane palm",
44 |   "deviceId": "AA:BB:CC:DD:EE:FF",
45 |   "interval": 300
46 | }
47 | ``` 
48 | 
49 | | Key           | Description | Optional / Required |
50 | |---------------|-------------|---------------------|
51 | | accessory     | Has to be `mi-flower-care`. | Required |
52 | | name          | The name of this accessory. This will appear in your HomeKit app. | Required |
53 | | deviceId      | The MAC address of your Xiaomi Flower Care device. | Required |
54 | | interval      | Frequency of data refresh in seconds. Minimum: 1 (not recommended); Maximum: 600 (due to FakeGato). | Required |
55 | | humidityAlertLevel | Humidity level in percent used to trigger the humidity alert contact sensor. | Optional |
56 | | lowLightAlertLevel |  Low light level in Lux used to trigger a low light alert contact sensor. | Optional |
57 | 
58 | Typical values for `humidityAlertLevel`are 30 (%) and 2000 (Lux) for `lowLightAlertLevel`. 
59 | 
60 | ## Running
61 | 
62 | Due to Bluetooth access, Homebridge **must** run with elevated privileges to work correctly i.e. sudo or root.
63 | 
64 | ## Note
65 | 
66 | The plugins is using Bluetooth LE (Low Energy) to connect to the Xiaomi Flower Care devices. Therefore, the first measured values are only visible after the first broadcast of the sensor. Up to this point the plugin is marked as inactive in HomeKit. In the worst case, the waiting time can last up to several minutes. Just have a little patience.
