Introduction: Control Your Esp6266 From the Internet? Free and Easy
How many times have we not looked for a simple way to communicate with our devices through the Internet without complications and / or complex intermediary applications, DNS, IP addresses or VPN's.
Many times I have been asked how to turn on a led, relay or view a temperature from the Internet in an easy way, here a possible answer.
For a long time I had in mind this application to control or interact an ESP8266 from the Internet using the existing IRC servers, it only requires 3 things an available IRC server, nickname and channel.

Step 1: Internet Relay Chat (IRC)
Internet Relay Chat (IRC)
Is IRC(INTERNET RELAY CHAT)is a transmission protocol (TCP/IP), which handles chats and asynchronous communication, chats can be in large groups of users or even one by one.
IRC exists since 1988, although currently it is not as popular as it was a few years ago but there are still many active groups, generally free software discussion communities, IRC servers are active, current and public.
IRC can implement Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to encrypt data between users, it also allows file sending. Most messages sent between an IRC client and the IRC server are sent in plain text.
Technically, IRC is a protocol that allows sending messages to one or many users, using commands for certain actions, such as "PRIVMSG" to send a message to a channel / group or user.

Step 2: ESP8266 IRC Client
ESP8266 IRC Client
You could say that creating an IRC client is very simple, technically make connections with a server for a certain port, send and receive messages, for some time I have done tests with esp8266 as an IRC client, I have made some improvements to the initial tests presented in previous tutorials.
To guarantee the existence or connection of the clients the IRC Server continuously sends "PING" to the client in this case ESP8266 would respond "PONG" indicating that it is still active in the channel, this verification is done automatically by our application.
The application has been created to work Answer by request, the ESP8266 will only respond under requests / commands or messages from external clients, it is preferred to avoid constant sending of data without being requested, bombing or perhaps blocking of IRC servers.
Step 3: Materials and Where to Buy Them Very Cheap !!
Materials and where to buy them very cheap !!
- ESP8266 12e NodeMCU
- Sensor DHT11
- Sensor DS18B20 Onewire

Step 5: Control and Monitoring = Commands
Control and Monitoring
Below I will list some of the features of the irc application implemented in an ESP8266, the main functions of Monitoring and Control, some commands have been created, which allow to request values, states or data from the esp8266:
Downloads: Arduino ide & Github code pdacontrolen.com
Step 6: Try With My ESP8266 Now .....
IRC Client
enter and send a command or if you want to download the code and test .. adding your ESP8266
Try now! .. I'll leave a esp8266 connected for a while, send commands from here ... an IRC Web client very easy.
- Command: "HIGH GPIOXX" example: "HIGH GPIO12" Turn on GPIO outputs
- Command: "LOW GPIOXX" example: "LOW GPIO12" Turn off GPIO outputs
- Command: "READ ADC0"
- Command: "ESP SIGNAL?"
- Command: "ESP Temp?" Temperature Sensor - DHT11
- Command: "ESP HR?" Relative humidity sensor - DHT11
- Command: "ESP Temp2?" Temperature Sensor - DS18B20
- Command: "ESP ?????"
- Command: "ESP8266IRCXXXXXX Help" or "Nicknameesp Help" - list available commands
- Command: sad face = :(
Step 7: Documents and Downloads
Some advantages
- Bidirectional connection through the Internet without registering to Applications, Token's or Platforms, I consider it an IoT application.
- Does not require Hosting, Public Fixed IP Addresses, VPN's, special ports.
- It is a simple TCP / IP connection, connection to a server and port 6777.
- IRC servers such as freenode are public have always been there.
- It allows to create temporary channels by a user, which are technically private, example "#TestESPChannel" could be used for private tests, said channel will only be active as long as there are users in it.
- By creating temporary groups we could create point-to-point P2P or M2M applications.
- IMPORTANT: Do not use existing channels or already used in any community, very public.
- There are IRC clients for almost all platforms, whether Android, Web, Python, C +, Arduino or Node-RED.
- The protocol guarantees the sending and receiving of messages between clients.
