I have a fused switch that controls an electric towel radiator. I am trying to understand where is the best place to place the Shelly 1PM, I think I have three options (See diagrams).
I would love to do option 3, but my understanding is the Shelly 1PM would then bypass the fuse and hence not a good thing
Code
Option 1
┌─────────────┐ ┌───────────────┐ ┌─────────────┐
│ │ │ │ │ │
─────► Shelly ├───► Fused Switch ├────► Radiator │
│ │ │ │ │ │
└─────────────┘ └───────────────┘ └─────────────┘
Option 2
┌──────────────┐ ┌───────────────┐ ┌─────────────┐
│ │ │ │ │ │
────► Fused Switch ├───► Shelly ├────► Radiator │
│ │ │ │ │ │
└──────────────┘ └───────────────┘ └─────────────┘
Option 3
┌──────────────┐ ┌─────────────┐
│ │ │ │
──────┬──► Fused Switch ├──┬────────────────► Radiator │
│ │ │ │ │ │
│ └──────────────┘ │ └─────────────┘
│ │
│ ┌──────────────┐ │
│ │ │ │
└──► Shelly ├──┘
│ │
└──────────────┘
