- Tue Dec 01, 2015 5:50 am #35426 I would like to make Switch which I can control from Domoticz. From Domoticz I can make on and of actions based on http but I have no idea how I can get this information by ESP8266 and set proper values to GPIO. Can you help me?
I write following code it connect to the wifi and initialize TCP server on port 1717(choose random). How I can do now that Domoticz send data to this specific port

Code: Select all-- Starts the module and connect to server.
print("SWITCH")

-- variables
local deviceID = "9"
local server_ip = "192.168.1.150"
local server_port = 8080
local deep_sleep_time = 300 --seconds
PIN = 7

-- wifi connection config
wifi.setmode(wifi.STATION)
wifi.sta.config("AKMEN","af66051515")
local cfg =
{
    ip="192.168.1.100" --..deviceID, --static ip based on id
    netmask="255.255.255.0",
    gateway="192.168.1.1"
}   

-- check every 0.5seconds if we can get an ip, once we get it start the TCP client
tmr.alarm(0, 500, 1, function()
    gotIP = wifi.sta.setip(cfg)
    if ( wifi.sta.status() == 5 ) then
        print("connected to WiFi")
        tmr.stop(0)

        -- restart the module after 30seconds if it's still ON:
        -- it probably means it's stalled
        tmr.alarm(1, 30000, 1, function()
            node.restart()
        end)
       
    end
end)

    server = net.createServer(net.TCP, 30)
    server:listen(1717, function(socket)
        socket:on("receive",function(socket, msg)
            print(msg)
        end)
    end)


I have also second issue I try to update switch status chenge it from off to on using json and following code. When I run this code I see in Domoticz change in last seen but nothing else. What is wrong?

Code: Select alldata="On"
local json = "GET /json.htm?type=command&param=udevice&idx="..deviceID..
                "&nvalue=0&svalue="..data..
                " HTTP/1.1\r\nHost: www.local.lan\r\n"
                .."Connection: keep-alive\r\nAccept: */*\r\n\r\n"

I haven't seen it done with json before. Have you seen the tutorial that Quindor put together. He does a nice job of outlining it in pure Lua.

Here is the code he has on his ESP8266:
