Hey everyone! I wanted to share a really cool project I recently completed. It’s all about converting an old stove hood fan and lights into a smart setup. I thought I’d document the process in case anyone else is interested in doing something similar. Purpose: I had a recurring issue with people forgetting to turn off the stove hood fan, especially in the winter when it sucks heat out of the house. It was also a pain to use the timer on the hood, so I needed a way to force the fan off after a set time without manual intervention. Parts Used: 1. Makergroup 12v Power Supply Driver IP67 - $12 2. Yitouniu Zigbee 4Ch DC7-32V USB 5V Relay Smart Switch Module - $24 3. Ururtm 1 Channel DC 12V-24V 100/240V Dry Contact Zigbee Smart Relay Switch - $15 4. Gebildet JD1912 Car Relay Harness 12V 40A 4-Pin - $8 Total: $51 Setup Details: The hood originally had a three-speed motor and 12v LED lights controlled by a touch panel. I used the Zigbee Relay board to control the fan and added a separate relay for the lights. I also integrated a 12v transformer to power the relays. The setup allows me to control the fan speeds and lights remotely, with an auto-off timer to prevent energy waste. Control System: I wrote a simple controller app that handles the fan speeds and auto-off functionality. I also added the lights to the system, making them part of the smart setup. The app connects to a virtual fan driver for easy control. Outcome: This project has been a game-changer for me. No more forgetting to turn off the fan, and it’s now fully integrated into my smart home setup. Plus, the lights are now part of my evening routines, turning on automatically when it’s time to cook. I’m really happy with how it turned out and would love to hear if anyone else has done something similar or has suggestions for improvements! If you’re thinking about a similar project, I’d highly recommend checking out the parts I used—they were reliable and affordable. Happy tinkering!
