Build a Reliable Off-Grid Long-Range Relay Switch with Meshtastic

In this video, I'll show you how I built a reliable off-grid long-distance relay switch. For this experiment, I used a 3.3V 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.
