Pro series (DIN rail)

What's in the series

Shelly Pro 1 and Pro 1PM for a single point, Pro 2 and Pro 2PM for two circuits or a shutter, Pro 3 for three dry-contact circuits (3-phase too), Pro 4PM for four circuits with metering, Pro Dual Cover for two shutters, Pro Dimmer for dimming lights, Pro 3EM for 3-phase energy metering, and LAN Switch for wired networking in the panel. The Pro Add-on adds connections for temperature and humidity sensors, analog inputs and dry contacts.

Smart DIN rail relays

A smart relay for the electrical panel snaps onto the rail like the rest of the equipment in the panel, and connects to the existing switches or push buttons in the house. A dry-contact relay (Pro 1, Pro 2, Pro 3) is right for switching a separate phase, low voltage or driving a contactor. The PM models also measure consumption and protect against overload.

Pro vs. Plus and Gen3: what's the difference

Plus and Gen3/Gen4 models are small and fit into the wall box behind the switch. They suit an existing home, without touching the panel. Pro models sit in the electrical panel, can also connect over a network cable (LAN) without depending on Wi-Fi, and bring the whole house together in one place that's easy to maintain. In new construction or a major renovation, Pro is usually the choice. For an existing home, a smart relay behind the switch is the right fit.

Shabbat timers and impulse relays in the panel

The same devices serve as a Shabbat timer for the electrical panel with a weekly schedule, and as a smart impulse relay that replaces old impulse relays and keeps the existing push buttons.

Why electricians prefer Pro

A clean installation on a DIN rail, a wired network connection (LAN) that doesn't depend on Wi-Fi, and inputs for existing switches and push buttons. The devices are accessible for maintenance from the panel and can be managed remotely from the app or through Home Assistant and MQTT. When a relay drives a contactor, it's worth adding a Snubber.

Planning the panel

In a new project or a renovation, it pays to plan all the electrical points together. We work with electricians and contractors on panel planning, and we'll be glad to help match the models to each circuit. You can also book an electrician who knows Shelly products.
