esp-homekit-multiple-sensors

This repository is based on the code and the examples provided by Maxim Kulkin.

https://github.com/maximkulkin/esp-homekit-demo

Detailed instructions on how to use the code found here can be found on Maxim's wiki.

In this repo there are two new examples:

a) multiple_sensors

b) multiple_sensors_ac

The first example creates a multi-sensor device in Homekit. It includes a Temperature, Humidity, Light and Motion sensor. The second example, is like the first example but it also adds a thermostat accessory. With thermostat accessory you can control an A/C through IR commands. Any new features will be added to the second example.

The following hardware can be used:

You may also use the following link to create a ready made shield for wemos D1 mini. https://easyeda.com/peros550/wemos-d1-dht22-ir-pir-lm393_copy

Final project would look like this:

Supported Features: *Dynamic Wifi configuration by creating a soft AP

*OTA updates

*ThingSpeak integration to save temperature & humidity values

*Webserver to configure special features (expiremental)

IR commands

If you are going to use IR, you need to supply your own set of RAW commands for your A/C in this file. You may use Maxim's esp-ir library to capture one by one each command for all modes (heating/cooling/auto/off). For AUTO mode there is only one command, I personally set there my A/C's FAN mode.

BOM

• 1 wemos d1 mini
• 1 DHT22 sensor
• 1 AM312 PIR sensor
• 1 LDR (i.e. a GL5528)
• 3 Resistors (18 Ohm, 2.2K, 10K)
• 1 NPN transistor 2N2222
• 1 IR LED (Had good results with TSAL6200)
• 1 push button (is used for homekit reset)
