Shelly Pro 4PM V1 (SPSW-004PE16EU)

Sensa Connection Method​

Network: Ethernet or Wi-Fi.

Installation​

Wire it into the circuits it switches, following Shelly's instructions. Connect it to your router or network switch by network cable, or use Wi-Fi.

Configuration​

It joins your van's network, and Sensa finds it there on its own by checking each address on the network for a Shelly. It works entirely inside the van, with no Shelly cloud account.

If your Shellys sit on a separate part of your network, change the Subnet next to the Scan button so that it includes that part, or Sensa will not find them.

Adding to Sensa Nomad​

Before you add it:

  • Turn the device password off in the Shelly app. Sensa cannot add a Shelly that asks for a password.
  • Give it a fixed address on your router, so Sensa can still reach it if the router hands out addresses again.

Then open Settings, choose the Devices tab, tick it under Discovered and press Add Selected Devices. If it is not there yet, press Scan.

The Devices tab, with devices ticked and ready to add

Its circuits start switched off in Sensa. After adding it, open Settings, find the relay's row and enable the circuits you use. They then appear on the Switches tab.

See Adding devices for more.

What you see​

Each circuit is a tile on the Switches tab of the Habitation dashboard, showing its live draw in watts, with the total for the whole unit at the top.

Good to know​

  • It warns you when a circuit is in trouble. If a circuit overheats, or draws too much power, voltage or current, the Circuit fault instinct raises an alarm naming it.
  • Settings lists eight channels. Every relay gets eight channel slots in Settings, but only the first four are real circuits on this unit. Channels 5 to 8 never appear on the Switches tab.
