The current-generation 2-channel Shelly, and the multi-protocol radio is the headline: WiFi 6, Zigbee (with repeater capability), Bluetooth and Matter all in one module, so it can join a Zigbee mesh as a router even while you drive it over WiFi via the native Shelly integration. Two 10A channels (16A combined, 18A peak) with per-channel metering and cover mode for blinds. Supersedes the older Shelly Plus 2PM, which is now legacy stock — buy this instead unless you find the Plus 2PM heavily discounted. Needs a neutral; Shelly hasn't published a no-neutral spec for this generation, so don't assume it'll run a no-neutral UK lighting loop without checking first.
What can Home Assistant control on the Shelly 2PM Gen4?
| Control | Type | What it does |
|---|---|---|
| Radio profile | Physical toggle (not an HA entity) | Secondary radio runs Matter (default) or Zigbee, never both; set by pressing the device button multiple times to open an inclusion window for the chosen protocol. |
| Switch (per channel) | Switch | Independent on/off control per relay channel, exposed regardless of which secondary radio profile is active. |
| Power/energy (per channel) | Sensor | Instantaneous power, cumulative energy, voltage and current reported separately for each channel. |
| Cover | Cover | Combines both channels into a single up/down entity when the profile is set to cover mode; supports position if calibrated. |
| Bluetooth proxy | Config | Passively forwards BLE advertisement data to HA's Bluetooth integration; works independently of the Zigbee/Matter profile choice. |
The native shelly integration only ever talks to this device over local Wi-Fi — Zigbee and Matter aren't connection paths HA uses, so pick the Zigbee profile if you want to run it as a mesh router while still driving both relays natively over Wi-Fi, rather than the default Matter profile, which forfeits that router role. Early firmware has shown up in reports with password-auth failures and intermittent connection timeouts on device-info polls, so treat this as newer, less-proven hardware than the Gen3 or Plus 2PM for now. Because the extender role runs independently of the Wi-Fi control plane, a single unit can plug the dead zone at the far end of a house, switch its own load through HA, and backhaul battery Zigbee sensors that would otherwise sit out of coordinator range — a trick no single-protocol Shelly can pull off.

Frequently asked questions
- Does the Shelly 2PM Gen4 work with Home Assistant locally?
- Yes. The Shelly 2PM Gen4 is controlled locally in Home Assistant through a built-in Home Assistant core integration (shelly), so it keeps working if your internet connection or the Shelly cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Shelly 2PM Gen4 use, and do I need a hub?
- The Shelly 2PM Gen4 uses Wi-Fi and Zigbee and Bluetooth and Matter. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly; or a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host; or a Bluetooth adapter on your Home Assistant host or an ESPHome Bluetooth proxy; or a Thread border router if it is Matter-over-Thread, or just your Wi-Fi network if it is Matter-over-Wi-Fi. Shelly's own hub is not required when you integrate through a built-in Home Assistant core integration (shelly).
- How much does the Shelly 2PM Gen4 cost in the UK?
