ESP8266-433mhz

I needed some really simple gateway to toggle cheap 433mhz power plugs (in germay mostly manufactured by Intertechno) from pimatic. I have no need to read anything back or be fancy. I needed something simple. I made something simple.

Build

See instructables.com or for a good german tutoral alexbloggt.com.

Install

• Change ssid and password according your needs
• Install libraries if needed
  • ESP8266WiFi
  • ESP8266WebServer
  • ESP8266mDNS
  • rc-switch
• Double check your DATA_PIN, for me it is D2
• Upload via Arduino.cc

Usage

Simply curl the api with the correct housecode and socketcode. I made usage of binary codes, as i can just read the dips without thinking.

curl -s "http://ESP-433-Gateway/changestate?housecode=<housecode>&socketcode=<socketcode>&state=<state>"

e.g.:

curl -s "http://ESP-433-Gateway/changestate?housecode=10001&socketcode=00100&state=on"

Pimatic device config could look like this:

{
  "onCommand": "curl -s  \"http://ESP-433-Gateway/changestate?housecode=10001&socketcode=00100&state=on\"",
  "offCommand": "curl -s  \"http://ESP-433-Gateway/changestate?housecode=10001&socketcode=00100&state=off\"",
  "echo": {
	"additionalNames": []
  },
  "id": "fusion_reactor",
  "name": "fusion reactor",
  "class": "ShellSwitch"
},

Home Assistant device config could look like this:

switch:
  - platform: command_line
    switches:
      tv_rack:
        command_on: "/usr/bin/curl -X GET 'http://192.168.1.94/changestate?housecode=10001&socketcode=10000&state=on'"
        command_off: "/usr/bin/curl -X GET 'http://192.168.1.94/changestate?housecode=10001&socketcode=10000&state=off'"
        friendly_name: TV Rack
