Sonoff Mini External Switch Reversing Function

jianwei87 — Sat, 26 Jul 2025 12:42:20 +0800

I’m using Sonoff Mini with external switch and followed this wire diagram to install it. I also have a Sonoff wireless button, SNZB-01P.

However, I’m facing an issue. When I turn on my Sonoff Mini’s external switch (which is supposed to turn off the water pump), the water pump doesn’t run. The function is reversed. I need to ensure that I turn off my external switch and use the Sonoff wireless button SNZB-01P to turn it off only works normally.

How can I resolve this issue? I need the external switch function to work normally regardless of whether the water pump is on or off. When I turn on or off the external switch, it should follow the state of the water pump.
