Using Mini 3A Relay Unit with ATOM Lite ESP32 - Boot loop

When I do a simple test with ESPHome version 2024.7.3, it does not work. The ATOM Lite always starts and runs in boot mode until SAVE mode.

Used parts:

• ATOM LITE: https://docs.m5stack.com/en/core/atom_lite
• RELAY: https://docs.m5stack.com/en/unit/relay

What is the workaround for this? Thank you in advance for your help

There looks to be some confusion between Atom Lite vs Atom Lite S3: https://shop.m5stack.com/products/atoms3-lite-esp32s3-dev-kit

Two different units, with different settings, and different pinouts. Is yours the white Atom Lite S3? If so, the pinout is wrong, see the README in the main repo. Is it grey like the Atom Lite? If so, try changing your board.

You can also clean your build files then flash without and mention of the relay at all, just get it built and online to ensure you've set that up correctly, then add the GPIO switch afterwards. That's how you'll know you have / haven't got the pins correct 😊

Thanks.

Solved: PIN 26

switch:
 - platform: gpio
   pin: 26
   id: relay
   name: "Relais"
