1. Overview

The Philips Hue Dimmer Switch V2 (12NC/part number: 929002398602; EAN: 8719514274617; Zigbee model ID: RWL022) is a battery-powered wireless 4-button dimmer remote made by Signify (formerly Philips Lighting), introduced in January 2021. It is the second-generation redesign of the original 2015 Hue Dimmer (RWL021), featuring a rounder form factor, a magnetic wall plate that allows it to be detached and used as a handheld remote, and an updated button layout with the Philips Hue logo on the On button. It communicates over Zigbee 3.0 and integrates natively with the Philips Hue Bridge, as well as third-party Zigbee coordinators via Zigbee2MQTT (Z2M), ZHA, and deCONZ. The product ships as a single unit (1x dimmer switch + battery included) and is designed exclusively for use with Philips Hue lights. It is manufactured by Signify, Eindhoven, Netherlands, and is consistently the #1 bestseller in the Switches & Dimmers category on Amazon Europe.

DATA QUALITY FLAG: The v2 (RWL022, 929002398602) uses a CR2032 battery. The v1 (RWL021, 324131092621) used a CR2450 battery. If the catalog records a CR2450 for this product (929002398602), that is incorrect and must be corrected to CR2032. Multiple sources confirm this distinction, including the official Zigbee2MQTT device page.

2. User Sentiment

The Hue Dimmer Switch V2 is rated 4.7/5 across 13,000–14,000+ reviews on Amazon (Belgium, UAE, Saudi Arabia, Egypt, Bahrain), placing it as a consistent category bestseller. Users praise its no-wiring installation, magnetic wall mount flexibility, and broad compatibility with Hue bulbs. The design is described as intuitive and usable by all ages. Community feedback from r/homeassistant, Jeedom, Simon42, and Home Assistant forums highlights strong third-party integration via Z2M and ZHA, though several known issues exist: in Z2M, double-press enabling breaks single-press recognition; ZHA (post-zha-device-handlers #2340) may fire duplicate events causing automation interruptions; and the native Hue Bridge allows cycling through 4+ scenes while Z2M only exposes recall_0 and recall_1. Users who migrated from v1 (RWL021) note that existing Z2M/ZHA blueprints for the older model work with v2 with minor adjustments, and that second-hand markets (Kleinanzeigen.de) show batch resale by power users deploying multiple units.

3. Real-World Applications

The Hue Dimmer Switch V2 is used primarily in residential smart home installations as a wireless wall switch replacement requiring no electrical wiring — particularly in rental properties or locations where hardwired switches are impractical. It is also deployed as a portable scene controller that detaches from its magnetic wall plate, enabling light scene recall from a bedside table, sofa, or anywhere in a room. Advanced smart home users integrate it into Home Assistant via Zigbee2MQTT or ZHA to trigger any custom automations beyond Hue lighting — including media player control. It is frequently bundled with Hue Bridge starter kits and sold as an add-on alongside Hue Play light bars, Hue GU10 spots, and other Hue ecosystem hardware. In Denmark, Norway, and Sweden (Dustin, Elektronik-lavpris), it is a standard offering in the wireless smart home switch category.

5. Ordering & Compatibility

The Hue Dimmer Switch V2 (929002398602) is sold globally at approximately €15–€27 depending on market: ~€14.90–€19.50 in Germany/France/Belgium, £13.52–£26.99 in the UK, ~$15–$17 USD in North America. It is widely stocked across EU and UK retailers including LDLC, Reichelt, Geizhals, Dustin, ManoMano, CCL Computers, AO.com, Ballicom, and Multiple Networks, as well as Amazon marketplaces worldwide. It is compatible with any Philips Hue light (requires Hue Bridge for full scene/routine functionality) and with Zigbee2MQTT, ZHA, and deCONZ for non-Hue smart home integration. A SAMOTECH SM200 V2 wall-plate adapter is available to fit the v2 dimmer into standard EU/UK in-wall boxes. When using Z2M/ZHA, direct device-to-device Zigbee binding is supported for controlling Hue or IKEA Trådfri bulbs without a coordinator. The v2 is not directly backward-compatible with v1 (RWL021) wall plates due to different form factor. Bundled with Hue Play Pack (915005733901 + 929002398602) at LDLC.

6. Known Issues

In Zigbee2MQTT, enabling double-press for a button disables single-press recognition — a documented bug in the awesome-ha-blueprints project (issue #425). ZHA users on HA 2025.3.0+ may experience automation kill-off due to ZHA firing two rapid sequential events per button action since zha-device-handlers PR #2340 (issue #713); a small delay in the automation workarounds this. In Z2M, only 2 scenes (recall_0 and recall_1) are exposed via MQTT for the Hue button — native Hue Bridge allows cycling 4+ scenes, which is a Z2M protocol limitation rather than a device flaw. Hold events repeat approximately once per second, so automations using *_hold for toggle actions may fire multiple times unintentionally.
