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.
