Homegenie is great piece of software. Recently I connected WiFi Temperature/humidity/luninosity sensors using ESP 8266 development board. If someone is interested how to do it reasonably fast here it is:
I used one of ESP 8266 Node MCU development boards (4-6$) like this
one then I used ESP Easy
firmware which let us connect many sensors / relays with no programming. Everything is available by web user interface. When you have Easy ESP connected to Wifi all readings from sensor are available through json interface
http://your_esyesp_ip/json. It looks like that
{"System":{
"Build": 147,
"Unit": 1,
"Uptime": 9,
"Free RAM": 26824
},
"Sensors":[
{
"TaskName": "oled1"
},
{
"TaskName": "rssi",
"Wifi RSSI": -54.00
},
{
"TaskName": "vcc",
"Input VCC": -1.00
},
{
"TaskName": "Lumos",
"Lux": 624.00
},
{
"TaskName": "DHT",
"Temperature": 21.00,
"Humidity": 41.00
},
{
"TaskName": "press",
"Temperature": 22.02,
"Humidity": 46.64,
"Pressure": 1013.10
},
{
"TaskName": "TempOut",
"Temperature": 2.19
}
]}
Then I prepared homegenie program (i'm not programmer, so i just adopted existing programs) which read this json and gives it to homegenie sensor widget. You have program below. You need to configure your ESP Easy IP and number of task you want to read (in example above Humidity from "press" task is number 5) and value name.
If you want to use it for relay - you can use another Homegenie app attached - easyESP Switch. It uses json API od Easy ESP to switch on/off relay. You need to configure IP adress in code.
I also found interesting chinese device called
Sonoff. It is 7$ relay with power supply and manual switch. It is intended to use witch chinese app on phone but it is based on ESP 8266 module. So you can connect USB-> comm adapter to
pins in the device and flash it with
ESP Easy Then you will have Homegenie operated ready for use Wifi relay just for 7$.
It works fine for me.
