Shelly Dimmer 2

Quick verdict

Shelly has discontinued the Dimmer 2 - it is no longer produced or sold - so new buyers should choose the Shelly Dimmer Gen4 for behind-the-switch installs, or the Shelly Pro Dimmer 2PM on a DIN rail. If you already own one, keep it: it hides behind your existing switch plate, gives you local dimming through the native Home Assistant integration or MQTT, and needs no cloud. The in-wall install was never for everyone, but the result is still a clean, fully local smart dimmer.

Standout: Hides the smart bits behind an existing switch instead of forcing a visible full-switch replacement; discontinued by Shelly Group, with the Shelly Dimmer Gen4 as the current behind-the-switch replacement.

Compatibility snapshot

Why it stands out

• native Home Assistant integration via local HTTP API or MQTT — no cloud needed
• works without a separate hub or coordinator since it connects directly over Wi-Fi
• hides behind your existing switch plate so you keep the original wall hardware look

Reasons to hesitate

• discontinued by Shelly Group and no longer produced (successors: Shelly Dimmer Gen4, or Shelly Pro Dimmer 2PM for DIN rail)
• install complexity is higher than plug-in smart devices
• box depth and wiring realities can be annoying
• not the easiest answer for beginners who just want a clean packaged switch

Best for

• existing Shelly Dimmer 2 owners who already have one installed and working
• retrofit projects where you want to keep existing wall hardware
• Home Assistant users who want local dimming without a hub lock-in

Avoid if

• you are buying new today (get the Shelly Dimmer Gen4 instead)
• you want the simplest mainstream smart switch install path
• you are not comfortable planning around wiring and electrical box constraints

Privacy and local-control notes

Strong local-control story when configured for local use, with far less dependence on vendor cloud behavior than mainstream Wi-Fi dimmers.

Home Assistant support: supported · integration path: native / local.

Buying reality check

Price notes: Discontinued by Shelly Group and no longer produced, so pricing is whatever remaining stock asks. Existing owners are fine and it stays fully local, but new buyers should get the Shelly Dimmer Gen4 (behind-the-switch) or the Shelly Pro Dimmer 2PM (DIN rail) instead.
