This is the non-dimming half of Fibaro's Walli pair, and it demands more from your wiring than a bare relay module: a neutral wire is mandatory, and it needs a full 60mm-diameter, 40mm-deep back box — check both before ordering. In exchange you get 13A per channel, 16A total, enough for loads the phase-cut Walli Dimmer can't touch. At £50.00 it still costs roughly double Fibaro's own Single Switch 2 module (£23.99) for the same relay function, and sits in the same finished-unit price bracket as the Walli Dimmer — pay it only if you want a complete switch plate, not a module hidden behind an existing one.
What can Home Assistant control on the Fibaro Walli Switch?
| Control | Type | What it does |
|---|---|---|
| Operating mode | Select | Standard on/off, turn-off-after-delay, or pulse (turn on then auto-off) — lets the relay act as a momentary output for gate releases, door strikes, or fan timers instead of a straight light switch. |
| Switch configuration | Select | Sets how the physical rockers map to the relay(s): both toggle together, independent per-channel control, or a 2-way/3-way wiring mode for single-switch installs with a remote physical switch on the same circuit. |
| Rocker press events | Event | Central Scene notifications per button per click pattern, independent of relay state — the same event model as the Walli Dimmer, so a rocker not wired to any load can still drive HA scenes. |
| Overload cutoff | Number | Relay-based cutoff far above the Dimmer's ceiling since there's no dimming circuitry to protect from thermal overload. |
| Association groups | Association | Sends on/off commands directly to other associated Z-Wave nodes on button press, bypassing the hub — a local fallback if HA or zwave_js is offline. |
Unlike the Walli Dimmer, this is a plain relay with zero calibration parameters — no load-type auto-detect, no dimmer-mode setting, no flicker-correction tuning, because there's no phase-cut circuitry to calibrate at all. Its standout switch-specific control is an operating-mode parameter that can turn the relay into a timed output — turn off after a delay, or pulse on then auto-off — for driving non-lighting loads like a gate strike or extractor fan rather than a light. Central Scene reporting works exactly like the Dimmer: independent flags per button per click pattern, so the rockers fire distinct events in HA even when not wired to drive the relay at all. Its overload cutoff also runs far higher than the Dimmer's since a relay has no dimming circuitry to protect from thermal overload, so it can happily switch high-draw resistive loads the Dimmer can't.

Frequently asked questions
- Does the Fibaro Walli Switch work with Home Assistant locally?
- Yes. The Fibaro Walli Switch is controlled locally in Home Assistant through a built-in Home Assistant core integration (zwave_js), so it keeps working if your internet connection or the Fibaro cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Fibaro Walli Switch use, and do I need a hub?
- The Fibaro Walli Switch uses Z-Wave. To pair it with Home Assistant you need a Z-Wave controller stick attached to your Home Assistant host. Fibaro's own hub is not required when you integrate through a built-in Home Assistant core integration (zwave_js).
- How much does the Fibaro Walli Switch cost in the UK?
- The lowest price we have listed for the Fibaro Walli Switch is £50 at Amazon UK. Prices were last checked in September 2026 and change often, so confirm on the retailer's page before buying.
