Winter grilling just got smarter! 
I’ve always been passionate about grilling, but the cold weather used to be a hassle. This year, I decided to automate my grill setup to make things easier and more efficient. Here’s how I did it and what I learned along the way.
The Challenge
Grilling in the winter means waiting for the grill to reach the right temperature before I can start cooking. I wanted to avoid trudging outside every few minutes to check the temperature. Plus, I wanted to monitor the grill’s performance without constantly hovering over it.
The Solution
I decided to create a smart temperature monitoring system using an ESP32 Wroom and a MAX6675 K-Type Thermocouple. The goal was to track the grill’s temperature in real-time and receive notifications when it reached the desired temperature.
Setup
Here’s the setup I used:
- ESP32 Wroom: For its versatility and Bluetooth capabilities.
- MAX6675 Thermocouple: To accurately measure high temperatures.
- Bluetooth Proxy: To integrate the system with my smart home ecosystem.
The configuration was straightforward:
yaml
spi:
clk_pin: GPIO18
mosi_pin: GPIO23
miso_pin: GPIO19
sensor:
- platform: max6675
name: “Grill Temperature”
cs_pin: GPIO4
update_interval: 5s
esp32_ble_tracker:
bluetooth_proxy:
active: true
I mounted the sensor inside the grill, ensuring it was protected from direct heat but still able to measure the temperature accurately. I also designed a small enclosure for the ESP32 to keep it safe from the elements.
Results
This setup has been a game-changer! I can now monitor the grill’s temperature from my phone or smart home dashboard. The system sends me notifications when the grill reaches the desired temperature, allowing me to start cooking without worrying about undercooking or overcooking.
Future Plans
I’m already thinking about enhancements. For example, I’d like to add a humidity sensor to monitor the smoking process and integrate it with my smart home’s automation system. I’m also curious about using this setup for my smoker, which I use occasionally.
