esp8266-pimatic

Send DHT22 or DS18B20 temperature and humidity data to pimatic server using an esp8266

Setup:

ESP8266

• Add WiFi credentials to init.lua
• Flash the esp8266 with the *.bin file here (or use your own custom build: http://frightanic.com/nodemcu-custom-build for more memory!)
• upload ether the *.lc version or *.lua version of the files & compile + upload all config files *_set.lua / init.lua
• Go to your esp8266 ip address and configure your client

Pimatic

• pimatic has to have two variables names can be custom --> see esp8266 config.
• to show the data on the homescreen add a VariablesDevice in pimatic

    {
      "id": "esp01-outside-wifi-temp-device",
      "name": "Outside",
      "class": "VariablesDevice",
      "variables": [
        {
          "name": "outsideTemp",
          "expression": "$variableName",
          "type": "number",
          "unit": "°C"
        }
      ]
    }

TODO:

• Add custom variable support
• implement "restart proofed variables
• add base64 encoding back (not enough memory for now)
• Support for PIR etc.
• Better way of storing the config..
• Change interval without resetting the device
• no humidity when using DS18B20
