PSF-Bシリーズ 1〜4連 超低消費電力 ESP8285 Wi-Fiスイッチモジュール

The ESP8285 chip sips power so slowly that my multimeter barely registers it in deep sleep, which is exactly what I needed for the 4-gang setup in my kitchen. Pairing took under two minutes and the web interface feels snappy for such a tiny module.

The wiring for my 4-gang setup took me an evening, but the ultra-low power draw is exactly what I needed—it's been running for three weeks and the energy monitor shows next to nothing. Streaming commands through the ESP8285 is snappy too, zero lag when I toggle each light from my phone.

Got this to switch two appliances in my workshop, and pairing it with my phone took less than five minutes. The 4-gang control means I can daisy-chain everything off one board, and the ESP8285 barely sips power in sleep mode. Solid little module for the price.
