In this video, I'll show you how I built a reliable off-grid long-distance relay switch. For this experiment, I used a LED strip from modern light bulbs, powered by the Meshtastic Radio board. Keep in mind that you could also use the board's 5V output. However, I wouldn't recommend using this relay to control household appliances—for those applications, you'll want to use a more appropriate switch. Like my previous video, this setup operates without cellular or internet connectivity, so there are no hidden fees—making it a cost-effective alternative to expensive commercial solutions. 🔧 RESOURCES 🌟🌟 🌟 Support the Channel🌟 🌟 🌟 The channel is affiliated with Amazon and AliExpress programs.
