Shelly powered by Spectoda
When integrating phase-switching input elements or output elements, we use Shelly products with Spectoda firmware.

The Shelly powered by Spectoda family groups partner/OEM modules with Spectoda firmware that we use for fast integration of inputs, relay outputs, and retrofit control into existing electrical wiring.

Important distinction
Section titled “Important distinction”- Shelly Plus i4 DC is a low-voltage DC variant.
- For mains 230 V inputs in the Spectoda portfolio, we use SC 4i A.
Pro 1andPro 2in this branch are listed as AC-only DIN modules.
How to work with these modules
Section titled “How to work with these modules”- if you need inputs under a switch, start with
Plus i4 DC - if you need one or two switched circuits, look at
Plus 1,Plus 1PM, orPlus 2PM - if you are working with a DIN cabinet installation, use
Pro 1orPro 2
