I attached both temperature sensor and extnernal bistable switch to sonoff basic.
If bistable switch is ON (loop closed = GND is connected to GPIO1), then after powering off sonoff it won't start, no led blinking, no wifi presence, nothing or works very unstable (very slowly loads part of configuration page).
After changing the circuit to open and replugging sonoff, it starts normally.
If I use GPIO sonoff works "boots up" always, regardless external switch state.

Hello,

this is rather minor problem, greetings
