Hey everyone! I wanted to share my recent success with integrating the AMG8833 sensor using ESPHome. This project has been a lot of fun, and I thought I’d walk through my setup and some tips in case others are looking to do something similar. 
First, I’ll start by saying that the AMG8833 is an amazing little sensor. It’s a thermal camera module that provides 8x8 grid temperature readings, which is perfect for monitoring heat sources in a room. Pairing it with ESPHome has been a breeze, and I’m really impressed with how well it works out of the box. Here’s a quick breakdown of how I got everything up and running:
-
Hardware Setup: I used an ESP32 module as the main controller. The AMG8833 is connected via I2C, so I wired it up using the standard SDA and SCL pins. Power is supplied directly to the sensor from the ESP32’s 3.3V output. I also added a small heatsink to keep things cool, especially since the sensor can generate a fair amount of heat during operation.
-
ESPHome Configuration: The configuration was straightforward. I used the built-in
amg88xxsensor platform in ESPHome. Here’s a snippet of my YAML config for reference:
yaml
sensor:
- platform: amg88xx
i2c_address: 0x69
update_interval: 60s
temperature:
name: “Thermal Camera”
unit_of_measurement: °C
accuracy_decimals: 1
-
Integration with Home Assistant: Once everything was set up on the ESP32, integrating it with Home Assistant was a piece of cake. I simply added the sensor to my configuration.yaml file and let Home Assistant do the rest. The sensor now appears in my dashboard, providing real-time temperature readings from the thermal grid.
-
Use Case: I’ve been using this setup to monitor the thermal activity in my living room. It’s particularly useful for detecting when the heating system kicks in or if there’s any unusual heat buildup near electronics. Plus, it’s just plain fun to watch the thermal grid update in real-time!
Here are a few tips for anyone looking to try this out:
- Firmware Updates: Make sure your ESP32 firmware is up to date. I ran into a minor issue with an outdated version, but a quick firmware update resolved everything.
- I2C Bus Stability: If you’re experiencing connectivity issues, check your I2C bus. A noisy bus can cause communication problems, so adding a small capacitor can help stabilize things.
- Heatsinking: Don’t underestimate the importance of heatsinking. The AMG8833 can get quite warm, especially during extended use, so a little heatsink goes a long way.
I’d love to hear from anyone who’s tried something similar or has any additional tips or tricks! 
Happy tinkering!
