大家都知道极米投影仪遥控器是蓝牙的，本身有非官方api但只能关机没法开机，所以想完美的接入系统还是有一些困难多亏了论坛的几位大佬之前做出的诸多努力，才有了如下终极解决方案：
一.极米投影仪软硬件简述
系统：android
遥控器类型：蓝牙（意味着没办法用其他遥控设备控制）
API：首先感谢以下几位大佬：

第三方集成：感谢这位兄台做了我想做但做不出来的东西！

上电自动开机：之前是没有的，前几个月官方系统更新推出了这个功能，让联动开机得以实现（借助智能插座）（如果你的上电开机功能异常，请在设置里关闭上电开机，完全退出设置后重新进入打开上电开机功能就可以正常使用了，应该是系统bug）
二、要实现的效果
1.能在hass和homekit里！！稳定的！！开机、关机
2.能正确的显示开关机状态（至少出门后能用手机看到投影仪是不是还开着）
三、思路
关机，如果简单的实现的话就直接给智能插座断电就好了，但我估计简单粗暴一定没有好结果（没测试过，哪位舍得自己的机器可以做个1000次上电断电的测试 ）
开机上面说了官方已经支持上电开机，所以需要备个hass能控制的智能插座
**那正常的开关机流程就是关机后看机器是不是真的关了，如果真的关了就断电，开机的时候通电就好了**
那怎么才能判断投影仪是不是关机了？
可以ping投影仪。**关机后ping不通** 就可以断电了当然如果你的智能插座功率数据读取是实时的，用功率判断是最准确的，但奈何小米的智能插座功率数据延迟很大（几分钟），实在是没什么用户
正确的显示状态：按照上面的逻辑，可以做个sensor，ping不通就断电，状态置为关机，能ping通状态就置为开机，
但有个问题，上电开机后有40秒是ping不通的，而且投影用wifi网络，日常ping会跳，万一跳的高了被断电。。。
所以干脆简单一点，**不做日常状态的判断，只在开关机的时候设置状态**
四、实际效果
hass上按开机按钮后会给智能插座上电，这中间会有1分钟延时，1分钟内会忽略所有的操作（避免操作进入队列，主要是homekit的操作队列机制不明朗），彻底开机后（网络通了）开关状态会变为“开”
关机时会通过api进行关机操作，然后会开始ping，ping不通后延迟3秒彻底关机后再断电
hass端：
找到了一个不错的media_player模板，可以模拟media player设备，控制更加方便
五、上代码
需要准备：
1.hass
集成：mqtt
nodered
** Media player template（记得重启hass）
前端：button-card（下面的遥控器部分用的button-card，上面是mushroom）
2.nodered
添加节点 node-red-node-ping node-red-contrib-home-assistant-websocket node-red-contrib-mqtt-bridge
3.mqtt
确保nodered hass mqtt通讯正常
nodered添加如下flow：
flows.json.zip
(10.82 KB, 下载次数: 91)
记得把ip地址换成投影仪的ip
flow会映射到hass里三个实体：
xgimi.power_off_button
xgimi.power_on_button
xgimi.state
hass configuration.yaml添加如下代码：
media_player:
- platform: media_player_template
media_players:
receiver:
friendly_name: Xgimi Z6X
device_class: receiver
value_template: >
{% if is_state("sensor.xgimi_state", "on") -%}
on
{%- else -%}
off
{%- endif %}
turn_on:
service: button.press
data: {}
target:
entity_id: button.xgimi_power_on_button
turn_off:
service: button.press
data: {}
target:
entity_id: button.xgimi_power_off_button
volume_up:
service: mqtt.publish
data: { payload: vol+ ,topic: homeassistant/remote/XGIMI}
volume_down:
service: mqtt.publish
data: { payload: vol- ,topic: homeassistant/remote/XGIMI}
mute:
service: mqtt.publish
data: { payload: mute ,topic: homeassistant/remote/XGIMI}
自己按照下面的图片格式化一下
喜欢用homekit的可以把设备映射到homekit里
lovelace添加：
