During the time Putin entered Ukraine, gas prices sky-rocket. Therefore, making improvements to the house's isolation was much to lower the monthly energy bill. Therefore, it became more important to understand where the house is leaking its heat.

I had some chip sensors lying around like the **MLX90640** and an ESP32-C3 (RISC) WiFi chip and connecting to any SPI screen that I had sounded too impractical. The MLX90640 is a thermal camera that has a 24x32-bit sensor. Using the I2C protocol the frames can be read.

If you Google for solutions, many of them are focused on an SPI LCD, but none of them is stream-focused like IP cameras. I wanted to use the ESP32 WiFi chip to display the thermal images to the phone in the browser. A cheap solution and a small solution.
