Using the Sonoff SV with a relay to open/close gate remotely by semiautomatix Aug 03, 2018 2 Sonoff

12V + and – (from the gate motor supply) to the sonoff + and – power input
sonoff SV output (+ and -) to relay input
relay output (NO contact) to gate motor trigger contacts

The relay can easily be purchased at Communica, Mantech or similar for about R10 a piece This will require some basic soldering skills and a bit of time (approximately 10 minutes I would say).

    Is it not possible to use a sonoff with inching to operate the gate (with no relay required), wired to come and no?

    Thanks Michael

      Hi Michael

      The Sonoff SV lastest firmware includes a pulse setting allowing you to use inching without additional equipment. Alternatively use the Sonoff 1 Channel.

      Kind Regards

      Tim
