# Hager WAC1020 Buy WAC1020 as part of a planned Hager A.x/C.x renovation when one coordinated wall station should keep a wired load familiar and add separate Matter actions. Skip it as a one-off smart-switch upgrade: the module is only one part of an expensive, professionally installed system.

It needs a compatible Hager insert, Matter controller and Thread border router. Local load control depends on the chosen insert; no Hager hub or app is required. - Launch date: 2026-05 - Thread border router required: Yes - Brand hub required: No - Typical price range: €61.80 module; about €109 basic controller set before delivery and installation (checked September 20, 2026) - Markets: Europe - Review status: Buying review - Product image: https://assets.matterhome.io/content/devices/hager-wac1020/product.73a4899ee18351ed888a/source.webp - Product image alt text: Official Hager Vertriebsgesellschaft press image showing the four-button WAC1020 module, white cover and frame, and a compatible flush-mounted insert ## What we like - Can combine familiar local load control with separate Matter commands - Fits four coordinated Hager A.x/C.x design ranges - No Hager hub, server or brand app required - Local load control keeps working without the smart-home connection ## What could be better - Module is incomplete without an insert, cover and frame - Basic hardware set costs about €109 before delivery or installation - Professional mains installation is required - Available button actions still depend on the chosen ecosystem and insert ## Best inside a planned Hager wall WAC1020 makes sense when the room is already being designed around Hager's A.1, A.8, C.1 or C.8 switch ranges. It can make an ordinary wall position do more without turning it into a glass touchscreen: a familiar rocker still handles the wired light or blind, while another pair of buttons can run Matter actions. That is a tidy result in a renovation where the frame, finish and electrical insert are being chosen together. It is much harder to justify as a single smart-switch experiment. WAC1020 is only the front application module. A working station also needs a compatible flush-mounted insert, a cover and a frame. The insert determines whether the wall position switches one or two circuits, dims a load, drives a blind or simply powers buttons that control other Matter devices. ## Give all four buttons a clear job The two-gang name describes four press areas, not two universal relays inside the module. With a one-channel relay or dimmer insert, the left upper and lower buttons can retain direct control of the connected load while the right pair is available for Matter functions. With Hager's two-channel relay insert, each half corresponds to a separate local circuit. On the power-supply insert, the buttons can be assigned through the smart-home system without a connected load. This flexibility is the reason to choose WAC1020 instead of the simpler WAC1010. A dining-room wall could keep physical dimming on one side and put a room scene on the other. A hallway position could become a four-command controller without pretending to switch a local lamp. The benefit disappears if the household cannot remember what the extra buttons do, or if the selected platform does not expose the press behavior the plan expects. Hager documents single, double and long presses at the hardware level, but the number of actions and their meaning depend on the connected smart-home system. Plan the actual commands in Apple Home, Google Home, Alexa or SmartThings before buying several modules. Home Assistant is not named in Hager's current WAC1020 material, so this is not the switch to buy on an unsupported assumption about exact button exposure there. ## The complete hardware price changes the decision At the September 20 check, one German retailer listed WAC1020 at €61.80 including VAT. A basic white A.1 controller-only set adds the WDN2061 power insert at €34.72, WAN7020WM cover at €10.68 and WAD6100WM frame at €1.94. That is about €109 before delivery and installation, even though it switches no wired load. Replacing the power insert with the retailer's €66.70 one-channel relay raises the same example to about €141. The exact total changes with the insert, cover, finish and frame, and electrician labor is separate. Premium A.8 and C.8 finishes can push it further. For comparison, [Aqara Light Switch H2 EU](/devices/aqara-light-switch-h2-eu) starts at €41.99 for one wired channel and extra scene buttons, or €44.99 for two channels, before its listed delivery and installation costs. Hager earns its premium when the coordinated switch range and modular insert choices are part of the project. Aqara is the more sensible starting point when the job is simply to make one suitable light switch smart. ## Local control is the right fallback The connected load can still be operated locally when Matter is unavailable. That matters more in a wall switch than another app feature: a visitor should not need a network lesson to turn on the ceiling light. The network path is native Matter over Thread, with a compatible Matter controller and Thread border router but no Hager gateway, server or brand app. This is still a mains product for professional installation. Hager requires a qualified electrician, limits the module to dry indoor locations and says the radio path is not for safety or alarm applications. The switch-system compatibility claim is also specific to Hager's new A.x/C.x platform; a familiar-looking 55 mm frame does not establish that an unrelated insert will accept the module. Matterhome has not tested the switch, button exposure or installation. Treat the selected ecosystem, insert and wall-box plan as one purchase decision rather than assuming the WAC1020 module will reproduce the same four controls in every home app. Choose WAC1020 when the installer is already specifying the Hager system and the right-hand commands have an obvious everyday purpose. For one isolated circuit, its modular elegance turns into cost and parts management. In that case, use a complete switch that fits the wiring or keep the existing local control.
