Code Improve/Advice, for Automated Blinds

Projects
1

Hi gents,
My wife asked me if i can make automated blinds in our living room and kitchen. I finished the project in the living room and kitchen is next. I scrambled a code for device and the agent with a little security. If you guys can take a look and improve it or help with my next version of it that would be awesome! here is my device code:

const SERVO_MIN = 0.06; const SERVO_MAX = 0.11;

hardware.pin9.configure(PWM_OUT, 0.02, SERVO_MIN);
hardware.pin8.configure(PWM_OUT, 0.02, SERVO_MIN);
hardware.pin7.configure(PWM_OUT, 0.02, SERVO_MIN);

agent.on(“value”, function (value) {

local value = value * (SERVO_MAX-SERVO_MIN) + SERVO_MIN; //0.01 + (value * 0.06);
try {
    hardware.pin9.write(value);
    hardware.pin8.write(value);
    hardware.pin7.write(value);
    imp.sleep(1);
}catch (err) {
        server.error("Error!");
    }

});

And the Agent Code:

local blindsState = "open"; local page = "" + "" + "" + "" + "
" + "Open" + "Close" + "" + "" + "";

function requestHandler(request, response) {

if(“/state” == request.path){
response.header(“Content-Type”, “application/json”);
response.send(200, getState());
}else if(“POST” == request.method){

local data = http.urldecode(request.body);

if ("value" in data && data["pin"] == "") { //set code
  server.log(data["value"]);
  if(data["value"] == "open"){
      device.send("value", 1);
  }else if(data["value"] == "close"){
      device.send("value", 0);
  }
}
//response.send(200, page);
response.send(200, page);

}else{
response.send(200, page);
}
};

http.onrequest(requestHandler);

My next goal is to add:

  1. Battery percentage if possible at all
  2. And a “Check Status” to check if blinds are Opened/Closed

Thanks for your time and help
