Which ESP32 board is best for a home automation hub with predictive maintenance and fault detection?
Hey guys i’m working on an ESP32-based home automation hub that includes predictive maintenance and fault detection. The setup uses FreeRTOS for managing tasks, MQTT for real-time communication, and sensors for temperature, humidity, motion, and power monitoring. The system will have around 10-15 sensors collecting data at varying frequencies, with a desired response time of 1-2 seconds. Considering the number of sensors and the need for reliable communication and processing, which ESP32 board would be best for this project? Any specific things I should keep in mind regarding memory, connectivity, or processing power?

@Daniel kalu The
ESP32-WROOM-32
or ESP32-WROVER
would work well for your project. If you need extra memory for handling multiple tasks and MQTT
communication, the WROVER
is ideal with its additional PSRAM
. Keep an eye on memory, Wi-Fi
connectivity, and processing power to ensure your system runs smoothly. The WROVER’s
extra memory offers more flexibility if your project grows.3 Replies
I recommend ESP32-WROVER it's 8MB PSRAM, powerful processor, ideal for multiple sensors and FreeRTOS tasks.
