Hello ESPHome enthusiasts! I’ve been experimenting with ESPHome on my ESP32 devices, specifically the esp32doit-devkit-v1, and I’m really impressed with its capabilities. Currently, I’m working on a project in my conservatory where I’ve set up a DHT11 sensor to monitor temperature and humidity. The configuration is straightforward and works perfectly, but now I’m looking to take it to the next level—battery-powered operation.
I’ve noticed that power consumption is a significant factor when running ESP32 devices on batteries. To address this, I’ve started exploring deep sleep modes, which I understand can drastically reduce power usage. However, my initial attempts have been a bit hit or miss. Sometimes the device sleeps too deeply and doesn’t wake up to send data, and other times it doesn’t go into sleep mode at all. I’m curious about how ESPHome communicates with the ESP32—does it actively send data to Home Assistant, or does Home Assistant poll the device? Understanding this could help me optimize the setup further.
I’ve also read about others successfully reducing power consumption by tweaking their configurations and using external low-power components. I’d love to hear from anyone who has experience with battery optimization on ESP32 devices. What strategies have worked for you? Are there specific libraries or settings within ESPHome that are particularly effective? Any insights or tips would be greatly appreciated!
Thank you all for your time and expertise. Let’s keep the conversation going and help each other make our ESPHome projects as efficient and battery-friendly as possible. Happy tinkering!
