ESP8266 WiFi LED dimmer Part 7 of X: Updated Dimmer and Domoticz code

I recently did a small addition to my dimmer code which gives you the ability to add the dimmer time to the sent values remotely. This way you can choose to dim quickly or slowly per dim action.

I made code for the ESP8266 modules and also changed my Domoticz code by cause the command input/protocol also changes. Currently you can't change the dimspeed setting in Domoticz itself, only by changing it by the switch associated LUA file.

The reason why I wanted to make these changes is because I want automatic/scheduled turning on and off of lights to be done very slow and smoothly but manual turn on (using a physical switch) to be fast and almost instant. Both need to run through Domoticz but would require different settings.

Domoticz Code

Then we need some new code for Domoticz, the general input line will now be the following:

echo Fadetimer1=9000,LED1_target=888 | nc -w 2 10.10.200.12 43333

Be sure to always keep the dimming value between 1000 and 9000! The "-w 2" adds a timeout value to the netcat command so Domoticz doesn't hang too long if the netcat command does not return when a ESP is turned off or not reachable. I made it a variable in the script so everyone can choose their own timeout.

commandArray = {}

DomDevice = 'ESP-01_PCB_1'

IP = '10.10.200.12'
Port = '43333'

LEDtarget = 'LED1_Target='
Fadetimer = 'Fadetimer1='
Waittime = '2'
FadeTime1 = '8000'

 if devicechanged[DomDevice] then
   if(devicechanged[DomDevice]=='Off') then DomValue = 0;
   print ("Turning off " .. DomDevice);
   runcommand = "echo " .. (Fadetimer) .."" .. (FadeTime1) .. "," .. (LEDtarget) .. "0  | nc -w " .. (Waittime) .. " " .. (IP) .. " " .. (Port) .. " ";
   print (runcommand);
   os.execute(runcommand);
 return commandArray
   else
    DomValue = (otherdevices_svalues[DomDevice]);
   end
   CalcValue = DomValue * 33;
   print ("Value received from Domoticz was " .. (DomValue) .." ");
   print ("Calculated value for ESP is " .. (CalcValue) .." ");
   print ("Dimming "  .. (DomDevice) .. " to " .. (CalcValue) .. " ");
   runcommand = "echo " .. (Fadetimer) .."" .. (FadeTime1) .. "," .. (LEDtarget) .. "" .. (CalcValue) .. " | nc -w " .. (Waittime) .. " " .. (IP) .. " " .. (Port) .. " ";
   print (runcommand);
   os.execute(runcommand);
 end
return commandArray
