I'm trying to create a remote control for my thermostat.
In my project when my phone is connected to the same wifi network as the ESP then everything works but when i switch it to cell data it doesn't. any idea's?

Code: Select allwifi.setmode(wifi.STATION)
wifi.sta.config("XXX","XXXXXXX")
print(wifi.sta.getip())
led1 = 3
led2 = 4
gpio.mode(led1, gpio.OUTPUT)
gpio.mode(led2, gpio.OUTPUT)
srv=net.createServer(net.TCP)
srv:listen(80,function(conn)
    conn:on("receive", function(client,request)
        local buf = "";
        local _, _, method, path, vars = string.find(request, "([A-Z]+) (.+)?(.+) HTTP");
        if(method == nil)then
            _, _, method, path = string.find(request, "([A-Z]+) (.+) HTTP");
        end
        local _GET = {}
        if (vars ~= nil)then
            for k, v in string.gmatch(vars, "(%w+)=(%w+)&*") do
                _GET[k] = v
            end
        end
        buf = buf.."<h1> A/C Control panel </h1>";
        buf = buf.."<p> <a href=\"?pin=AC\"><button>Ac</button>";
        buf = buf.."<p> <a href=\"?pin=Heat\"><button>Heat</button>";
        buf = buf.."<p> <a href=\"?pin=OFF\"><button>OFF</button>";
        local _on,_off = "",""
        if(_GET.pin == "AC")then
              gpio.write(led1, gpio.HIGH);
               gpio.write(led2, gpio.LOW);
        --elseif(_GET.pin == "OFF1")then
             -- gpio.write(led1, gpio.LOW);
        elseif(_GET.pin == "Heat")then
              gpio.write(led2, gpio.HIGH);
              gpio.write(led1, gpio.LOW);
        elseif(_GET.pin == "OFF")then
              gpio.write(led2, gpio.LOW);
              gpio.write(led1, gpio.LOW);
        end
        client:send(buf);
        client:close();
        collectgarbage();
    end)
end)

As far as how the thermostat project is going i took apart my honeywell unit and it has a complicated(heat-off-cool) switch, i was hoping it was a on off on switch but its a slider type with 20 pins and to reproduce its function would require 8 relays

To access your ESP from outside your LAN you have to set your router up to port-forward requests and then use your router's public IP address.
