About this product
The Shelly 1-Channel Decoupler 230V is a passive wiring accessory, not a stand-alone smart device: it always works together with a Shelly module. At its core is an optocoupler (optical interface) that galvanically isolates the 230V~ circuit from the low-voltage side and generates a safe DC signal from an already existing AC signal.<br><br>This lets you keep a 230V wall switch or a relay output and pass the command to the low-voltage (DC) input of a module such as Shelly Plus RGBW PM, Pro RGBWW PM, Plus Uni or Plus Add-On. Key parameters: 230V~ 50 Hz input, maximum output current 2.4 mA, consumption below 0.6 W, dimensions 48x13x7 mm, weight 14 g, 80 mm cable, operating temperature 0...40 degrees C. Installation must be performed by a qualified electrician.

Frequently asked questions
Is the Shelly 1-Channel Decoupler a stand-alone smart device?
No. It is a passive wiring accessory that does not connect to Wi-Fi and does not work on its own. It needs a compatible Shelly module on its DC input.Which Shelly modules is it compatible with?
The manufacturer lists Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni and Shelly Plus Add-On.What does this decoupler actually do?
It uses an optocoupler to turn an existing 230V~ signal into a safe DC trigger (max 2.4 mA), galvanically isolating the mains from the low-voltage input of the Shelly module.When do I need it?
When you want to keep a 230V switch or relay output and use it to drive a DC input of a Shelly controller without pulling new control wiring.Can I install it myself?
It is not recommended. It works directly with 230V~, so installation should be done by a qualified electrician with the power off and following the Shelly diagram.What warranty and availability does it have at CasaSmart?
The product has a 24-month warranty. It is currently shown as out of stock; contact CasaSmart for supply lead time and the current price.
