Shelly Wave 2PM dual-channel Z-Wave relay

Quick verdict

Two relays in one Z-Wave module, each with its own power monitoring. Ideal for dual gang switch boxes or anywhere you need to control two circuits independently. Runs fully local through Z-Wave JS in Home Assistant. Bigger than the Mini, so measure your box first, but the dual-channel capability makes it extremely versatile for behind-switch installations.

Standout: Dual-channel Z-Wave relay with independent power monitoring on each channel.

Local control facts

Home Assistant: zwave_js integration, Local Push (home-assistant.io, checked Oct 10, 2026)
Z-Wave JS: in the device database, listed as Shelly Europe Ltd. QNSW-002P16EU / QLSW-002P14US (Wave 2PM) (github.com, checked Oct 22, 2026)

Why it stands out

two independent relay channels in one device, letting you control two circuits from a single module
per-channel power monitoring gives you granular energy data
Z-Wave mesh means no Wi-Fi interference and solid range through walls

Reasons to hesitate

requires a Z-Wave controller on your Home Assistant setup
bigger footprint than the Wave 1PM Mini (37 by 42 mm against 29 by 35 mm, same 16 mm depth), and the Mini is not sold on the US store
no Matter or voice assistant integration without Home Assistant in the middle

Best for

Home Assistant users who need to control two circuits from one box, like a dual gang switch or two light groups
Z-Wave network builders who want per-channel power monitoring

Avoid if

you only need a single channel, since the Wave 1PM is cheaper
you do not have or want a Z-Wave controller

Privacy and local-control notes

Fully local via Z-Wave. No cloud, no internet needed. Power monitoring data for both channels stays on your network.

Home Assistant support: supported · integration path: Z-Wave JS.

Buying reality check

Price notes: Good value for a dual-channel relay, cheaper than buying two single-channel modules.

Black Friday smart home deals for Home Assistant: the prices to beat

Black Friday 2026 smart home deals for Home Assistant and local-control homes: the lowest price I've recorded for 100+ Zigbee, Z-Wave, Matter and Wi-Fi devices.
Sep 7, 2026 · Corrected

Shelly follow-up audit and 16 more corrections

Six more Shelly products went through the same source check as the rest of the catalog. The Plus i4’s inputs are mains-level, not dry-contact (the DC model is the low-voltage one). The BLU Motion, BLU Button1 and BLU Door/Window pages no longer say a Shelly gateway is required: a Bluetooth adapter on the Home Assistant host or any Bluetooth proxy hears them directly. The Wall Display XL mounts to a standard switch box, and its dashboard claim now says exactly what Shelly ships: a Home Assistant page that loads a dashboard URL, deprecated and then restored in firmware 2.7.0. Five manufacturer links that had gone dead were replaced, the ZEN04 price was refreshed, the Tedee GO page names the official tedee integration as its non-Thread local path, and the G6 Instant page notes its IPX5 rating.

From the change log and the news briefs that name this product.
