Setting up Ampy's outputs: every output becomes a widget

Updated 9 October 2026Ampy

In the dashboard every output gets a widget, and while doing so you choose what is actually connected to it. The widget then looks like the function, not like a technical power channel.

The setup wizard

  1. Choose the device. Select the Ampy, if you have several a meaningful name helps.
  2. Choose the output. Which of the six outputs you are using.
  3. Choose the load template. What is connected there, see the list below.
  4. Confirm the details. For example fuse value and behaviour.
  5. Name and icon. So you recognise the widget straight away.

After that you can rename any widget at any time, add it to your favourites or adjust it, without any rewiring.

The templates

  • Light: on and off with dimmer, can be included in light scenes
  • Water pump: pump switch with a slow fuse for the starting current
  • Device or load: universal switch with consumption display, for example fridge, inverter or fan
  • Boiler or heating: switch with suitable fusing
  • Frost guard: switches the frost protection circuit
  • Awning, entry step, lift bed: motor control with run time and direction lock
  • Pop-top roof: up, neutral and down over two outputs, with limit switches or run time
  • Air diverter: two named outputs instead of on and off
  • Drain valve: valve control, can be linked with the water tank

Related questions

Does Ampy work on 12V and 24V?

Both. Ampy detects the vehicle's electrical system automatically, so there is nothing to change.

How is Ampy connected?

The supply goes onto two M6 threaded studs, the loads into lever terminals for up to 4mm²: open, insert, close, no tools needed. The push button wires go into removable spring terminals.

How much current can an Ampy output draw?

24A continuously, up to 32A for short periods, and 120A across all six outputs combined. So even a compressor fridge, an inverter and a parking heater fit on a single output.

Do I still need to buy fuses for Ampy?

Not for the loads connected to Ampy. Every output has an electronic fuse that you adjust instead of replacing.

What happens when a fuse on Ampy trips?

The output switches off and you see it in the dashboard, including the reason. Resetting takes a single tap. If the fuse trips several times in a row, Ampy enforces a short pause so that a genuine fault is not simply glossed over.

Fast, normal or slow: which tripping characteristic should I choose?

The characteristic determines how quickly the fuse cuts out when the current is too high. As a rule of thumb: slow for anything that briefly draws more when it switches on, fast for pure electronics, normal for everything in between. • Choose slow for motors and compressors: water pump, fridge, fan, awning, pop-top roof, inverter. These loads draw several times their continuous current at the moment they switch on, which is completely normal. A fast fuse would trip every time, even though nothing is wrong. • Choose fast for loads without inrush current, such as LED strips, sensors, control units or charging sockets. Here a sudden rise in current is almost always a fault, and then it should cut out quickly. • Normal is the safe choice if you are unsure. A practical tip: if the fuse only trips at switch-on while the continuous current is fine, set it one step slower. Raising the fuse rating instead would be the wrong approach, because the rating still has to match the cable cross-section.
