LoRa ESP32 Home Control Prototype

I have a proof-of-concept in mind that will let me switch household appliances on and off from a distance using LoRa and an ESP32. The focus is purely remote control—no fancy scheduling or parameter tweaking for now—so reliability, range and low-latency switching are the priorities.

I already work with the Arduino IDE and PlatformIO, but I need someone who has hands-on experience pairing ESP32 boards with the right LoRa transceiver (SX1278, RFM95, or any module you know performs well). You’ll guide the hardware choices, write the firmware, and make sure the receiver node triggers a solid-state relay (or a simple LED during testing) whenever the transmitter sends an ON/OFF command.

Deliverables:
• Schematic or wiring diagram for both transmitter and receiver nodes
• Well-commented ESP32 firmware for each side, compiling in Arduino IDE
• Brief range and power-consumption test results, plus any tuning tips
• Quick setup notes so I can reproduce the build on my bench

If a demo video or live walkthrough fits into your normal workflow, that would be a bonus, but the must-haves are the diagrams, code and clear replication steps.
