Extend the UDP message sender Cookbook with 8266 example

[nagyrobi]

Description:

Extended the configuration example of "Send UDP commands" cookbook entry form the "Lambda Magic" chapter with working yaml for ESP8266. This is important because many think that the WiFi implementation of ESP8266 lacks UDP, but WiFiUdp library comes to help with a simple inclusion (which btw is used by two other components).

Walkthrough

The changes to cookbook/lambda_magic.rst enhance the UDP command sending functionality in ESPHome scripts using Lambdas. The update introduces specific implementations for both ESP8266 and ESP32 platforms, incorporating UDP packet sending logic and updating logging details. Platform testing information has also been revised to reflect these updates.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Can this entire section of the cookbook be removed due to the udp component?

This has no direct relation to the UDP component because it targets sending UDP packets to any third party devices, with any arbitrary data inside. The UDP component is for communication between ESPHome nodes, while these examples show how to send UDP commands to anything else.

I use these with great success in controlling a BrightSign player.
