I've installed a sonoff mini and connected the signal wires to 3 3 way wall switches.
If I try to switch ON/OFF the sonoff using the app, there is no problem, it works like a charm always, but when I do it using the wall switches it just works "sometimes".
For what reasson can it be caused?
Is there any maximum length for the wires?
Should I activate any flag in the app?
Rather, not random but untimely. It is caused by some interference.
I have also tried the solution, and it seems to work, the switch works without delay, and there is no flickering. I hope it remains so!
merci pour le retour , j'attend de le recevoir pour tester aussi.
Same for me... installed the condenser and and the sonoff is now stable on the "external" switch S1 S2.
The capacitor must be 100nF / 50v ?????? or can it be mounted with another voltage?
Can't mount 100nf / 50v SMD capacitor?
problème corriger avec un condenseur en s1 et s2
