Sonoff POW Elite 16a (POWR316D)

Bootloop Workaround

Some people experience a boot loop after flashing esphome directly. The boot loop seems to appear on 3.3V DC power only (not on AC). Here's a workaround: https://community.home-assistant.io/t/bootloop-workaround-for-flashing-sonoff-th-elite-thr316d-thr320d-and-maybe-others-with-esphome-for-the-first-time/498868
