Raspberry Pi has raised prices on many Pi 4, Pi 5, and Compute Module models as memory costs surge in 2026, undermining its once-low-cost SBC positioning.
I have a n ESP32 with a thermocouple stuffed down my (gas) oven chimney, so I can tell what temperature it actually is (about 40°F/20°C cooler than the dial).
I have one plugged into an addressable LED matrix, which has yet to get mounted, but will eventually be a closet/dressing light. There’s a few places where I’d like a ‘normal’ warm white light, with the option to switch to a blinding daylight for chores, and maybe a low-light, colorful animated nightlight.
I have a Pi-0w reading temp/humidity/CO2 in a grow tent that’s a good candidate for ESP32-ification. I have an air quality sensor plugged directly into a Home Assistant server that could go on ESP32 if I wanted it in a different location. Humidity in the bathroom, with a controller for the bathroom fan is another good candidate.
If I can come up with a good way to put them on battery, with a 6-12 month lifetime, then temperature in the attic, and on the input/output sides of the HVAC would be useful.
