DieseRC DC 12V 24V 30V Wireless Remote Control Switch 433Mhz RF 10A Relay Receiver with 2 Transmitters for Motor, Light, Gate Door, DIY Controller

Bought an old house and needed a set of clickers for the garage doors. The old ones were lost by the previous owners. The openers still had push buttons on the wall but no remotes so I took a chance on this device. Turns out that it works great. The radio needs an external DC power supply between 6 and 30vdc. I used an old 12vdc power brick from an old laptop, just cut the end off and spliced the wires into the supply terminal (the one with the 3 screws). Programing is a bit tricky, as others have stated, you need to do it quickly, so familiarize yourself with it first. Button A controls relay#1 .. button B controls relay #2, you only need to program the remote once as a single programming session handles both relays. In fact I programmed the remotes on a bench before installing them on the ceiling. I programmed the device for a momentary connection (since the garage door buttons are like touching two wires together). You'll hear the relays when they click in (ie. pressing the A button) and when they click out (ie. releasing the A button). I used the NO (normally open) and COM (common-ground) connections on the relays for this.

Bed bediening, werkt nu draadloos.

Klappt gut und zuverlässig. Reichweite ist auch wirklich gut.Nachtteil: Das funk signal ist nicht verschlüsselt und kann einfach kopiert werden. aber das ist bei fast allen günstigen Funkmodule so.5 von 5 Sterne =)

Pour commander à distance un moteur de volet de piscine. Programmation facile. Notice claire et facile à comprendre pour les trois modes possibles. Pour le moment je l'ai seulement testé sur table. Je vais le mettre en utilisation réelle et j'en dirai plus ultérieurement.

Works as advertised, remotes feel good, casing supports hanging up with screw
