Shelly Wave 2PM

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.

Compatibility snapshot

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 WiFi interference and solid range through walls

Reasons to hesitate

• requires a Z-Wave controller on your Home Assistant setup
• larger than the Mini variant, so check your switch box depth before buying
• 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 1PM Mini is smaller and 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.
