M5Stack ATOM Matrix体验以及使用esphome接入homeassistant模板

前言：

最近购入了一个ATOM Matrix，挺喜欢。模块化设计，方便使用的同时也很迷你。买入它的原因是为了使用他自带的mpu6886陀螺仪模块，同时他使用的esp32，方便我使用esphome进行接入。

产品细节：

东西到手后发现做工一般般，总体上说的过去，但是略有瑕疵。提供的资料也有限。自带有测试程序，按键会自动变换显示内容。灯珠如果长时间处于高亮状态会略微发烫。背后以及低端有io口，可以和其他模组直接插接组合使用，非常方便。

官方说支持Arduino，以及他们提供的图形化编程软件UIFlow，看起来挺有意思。不过既然核心是esp32，那么应该也支持esphome。所以我决定用esphome把他接入homeassistant。

接入homeassistant：

花了一点时间尝试使用esphome接入，大部分成功。包括：按钮，加速度仪、角速度仪，5*5灯板，均可在homeassistant中进行操作。

以下为提供模板：

注意：由于zdm不支持代码块，粘贴yaml代码会导致缩进错误 ，我将yaml代码转换成了json代码。如需使用则将json代码转换为yaml代码即可粘贴进esphome。

============================代码结束===============

接入成功后效果：按钮以及灯光控制。

总结：

使用中的个人主观感受。

优点：

设备整体小巧，集成度高，造型还算美观，不需要再弄个外壳。配合其他零件插接方便，很喜欢这种模块化设计。

缺点：

使用中任务重的时候发热较大，灯光不建议长时间工作在高亮度，红外范围较小，io接口相对较少。
