If some one can help/clarify me here please. I could have buy one and test is myself, but its a long wait in the postage to arrive.
I am looking for 1 CHANNEL INCHING /SELF-LOCKING Device. Wanted to know will it retain state when the device power is off.
I have a situation, when relay is ON, even when device lost it power, I wanted to keep the relay in same state ON.
I am confused with the term Self-Locking.
Appreciate any explanation.
Thanks E W. Appreciated your quick response.
As far as I know all Sonoff devices "latch" electronically and not mechanically. Meaning that with no energy available the relay will de-energize.
