Amoque, What is, or what are the devices you are setting the on/off/day commands to? I personally have had good experiences using one of the ESP8266 devices with ESPBASIC. That way you can have a WIFI interface to your device. You can set up the web interface with buttons and switches as well as sliders for variable data. ESPBASIC is free and the devices I have used are the ESP8266-1 512k and the LOLIN 4M modules.
