So I thought I was very bright to use the Sonoff inching switch (
https://www.smartkit.co.za/product/1-channel-inching-self-locking-wifi-wireless-switch-5v-12v/?attribute_voltage=5V/12V) to operate my gate motor remotely for visitors. I did this by allowing the sonoff to bridge the remote button on the Centurion D5 gate motor. It works very well. I press the button in the eWelink app and the sonoff "pushes" the button for 1 second and the gate opens. Push it again and it closes.
Little did I know that when the sonoff looses power and powers up again it momentarily latches the relay as part of the booting cycle in the process opening up the gate. (The power on state IS set to OFF in the eWelink software).
Thing is, I had this set up for more than a year and only notices it now. Could this have been introduced via a new firmware update. I am pretty sure it wasn't always like this.
Can somebody else confirm this as normal?
Thanks
