Home Assistant ESPHome Series: ESPHome ( ESP8266 & ESP32)

ESPHome 是一套工具，由 ESPHomelib 和 ESPHomeyaml 组成。前者安装在 ESP8266 或 ESP32 上，后者用于为其编译固件。

ESPHomelib 主要通过MQTT 与 Home Assistant 通讯，可以说专为 Home Assistant 而设计。简单易用且支持硬件多，可以通过简单而强大的配置控制ESP8266/ESP32，还可以通过接入家庭自动化系统实现远程被控。

在物联网里有一个固件叫做 ESPHome，它是一个通过简单而强大的配置文件控制 ESP8266/ESP32 并通过家庭自动化系统远程控制。

ESP8266是一个开发版(屏蔽了我们对电路知识的了解)

ESP32是一款低功耗的蓝牙和Wi-Fi模组。
它是ESP8266模组的替代产品。
支持蓝牙低功耗(BLE)4.x和Wi-Fi 802.11 b/g/n协议。

classic ESP32 boards and the new models: ESP32S2, ESP32C3 and ESP32S3

You will also need an ESP device such as the Wemos D1 Mini or ESP32 board a.
Usually the boards have an on-board USB port so simply connect it to your computer.


microcontrollers used in IoT products, both for manufacturers and creators in the DIY space.

Microcontrollers are teeny tiny computers with little processor power, memory and space that can interact with sensors, send infrared commands and many other things.

program the ESP32 via the Arduino IDE. You will then write your first program for the ESP32 using Arduino code.

稳定性

你要搞清楚。你的8266 是芯片8266 ，模块ESP-12F 还是成品（开发板）D1 MINI，nodemcu 。
如果 不是成品 就有可能 是你的设计电路有问题。
用成品是正常的，没有事的

用老版的8266的nodeMCU，加个1820传感器Lua脚本，上传乐为物联，连续跑了一年半，温度曲线都正常，没有重启过。



The Home Assistant integration consists of two parts:

node sensors: each ESP32 appears as a device automatically (because MQTT auto discovery), including entities to set max distance and disable/enable active scan or query

beacons: define each beacon in configuration.yaml (using mqtt_room integration)


software一ESPHome

买esp32，装esphome

ESPHome is a powerful bit of software that allows custom firmware to be compiled for smart home devices

There are two parts to ESPHome, the configuration tool and the firmware

With ESPHome users don’t program microcontrollers, they configure them. Tell ESPHome there is a temperature sensor on pin 3 of your ESP device and ESPHome will install custom software on your ESP device that makes this information available in Home Assistant.

目前z2m，接了22个绿米和小米的传感器，很稳定。

生态子设备。如果要用各种品牌的zigbee来个大杂烩（设备品类齐全，并且价格便宜，可以省很多钱），那么用z2m，硬件用cc2652p usb棒。

ESPHome 支持接入小米的蓝牙设备 Xiaomi Mijia BLE Sensors。可以直接利用 ESP32 充当蓝牙网关获取蓝牙设备的数据。

在esp32上装上esphome,可diy 制作蓝牙网关，接入米家传感器，实现蓝牙设备夲地化。接入ha

ESP8266
ESP8266系列.ESP-01系列，相应的还有ESP-02，03等等，它们使用的核心芯片都是相同的。

ESP8266 - ESP-01
ESP-01做为MQTT的客户端，连接到MQTT Server， Home Assistant通过mqtt组件和MQTT Server通信，实现控制ESP-01的功能

How to connect ESP32 to home assistant

This esphome integration allows ESPHome devices to connect directly to Home Assistant with the native ESPHome API.

We identified three pain points:

Installing the software on the microcontroller.

Connecting the microcontroller to your wireless network.

Configure the software on the microcontroller.


Open source software like ESPHome, WLED and Tasmota allow users to turn their ESP8266 and ESP32 devices into powerful little machines that can gather information and control devices


Microcontrollers are just computers and so are nothing without their software.

Tasmotizer tool
Flashing and configuration is made very easy when done with the Tasmotizer tool. It does however lack the functionality offered by ESPHome.

ESP Web Tools Web has already been adopted as part of the onboarding by WLED and ESPEasy.

ESP Web Tools allows project websites to offer a great onboarding by enabling users to install the software on their microcontrollers via their browser. All the user has to do is connect their microcontroller to their computer and hit the install button on the website. ESP Web Tools will automatically select the right build for your microcontroller and install it.

they are cheap. Like, $5-including-shipping-from-China-cheap (AliExpress) or $15 for 2 on Amazon cheap.



板载开关
ESP32开发板具有两个按钮。一个标记为EN位于左上角的是复位按钮，用于复位ESP32芯片。左下角的另一个引导按钮是下载程序时使用的下载按钮。
