Sonoff MiniR4 Extreme Boot Loop

ESPHome
1

After successfully flashing the MiniR4 and resetting, the device constantly reboots. I am using the default config from the ESPHome Sonoff MiniR4 page. Even if I flash the unit with a blank config it still reboots constantly.

Hello. I think I had that issue. This happened for me when I was powering the device via USB after I flashed it. If you power it at mains voltage this issue might go away. Seems like it tries to draw more power than the usb can supply as it starts up Wi-Fi.

That was it! I used a bench supply and it’s working fine.
