Three DIN-rail Shelly Pro 2PM units switch six lighting circuits or three roller shutters, the Shelly Pro 3EM measures consumption and the LAN switch wires everything back to the router. It is built for detached houses where the board is being rebuilt or extended: the controls stay on the existing push-buttons, with the app, schedules and voice assistants added on top.
What it does
- Each Shelly Pro 2PM has two channels: it drives two lighting lines or, in roller shutter mode, one motor up and down.
- The existing wall buttons wire to the module inputs and keep working even with no network.
- Each channel measures the power drawn: you can see how much a lighting line uses or how long a shutter takes to travel.
- The Shelly Pro 3EM, with its current clamps, measures the whole-house load or three separate circuits.
- The 5-port LAN switch in the board wires the Pro modules together and carries the network back to the house router.
- In the Shelly app you set schedules, scenes such as "all down" in the evening and consumption alerts.

Before you order
Do you need a hub?
No. The Shelly Pro modules connect to the home network through the LAN switch included and the router, and are managed from the Shelly app. There is no coordinator to buy: the home router, not included, is the connection point for the whole panel.
Does it work with Alexa and Google?
Yes, with the Shelly integrations you switch on in the app: the lights and roller shutters show up in the voice assistant and are controlled by voice. What you get depends on the assistant's integration; schedules, scenes and consumption figures stay in the Shelly app.
Do you need an electrician?
Yes. The whole kit goes in the 230V distribution board: modules, enclosures, measuring clamps and the push-button wiring. The connections must be made by qualified personnel with the installation isolated, and it is worth doing them at the same time as any rework of the board.
What happens if there is no internet?
The wall buttons carry on controlling the lights and the roller shutters, because they are wired straight to the modules. The modules also stay reachable on the local network as long as the router is on. Without internet you lose control from away and the voice assistants.
Can I add devices?
Yes. The enclosures have spare ways and the switch has free ports for more Pro modules. Flush-mounted Shelly Wi-Fi devices can be added in the rooms as well; they appear in the same app and work in the same scenes.
Does the Pro 3EM work on a single-phase installation too?
Yes: besides three-phase measurement, the manufacturer states it can measure three separate single-phase circuits, the main supply, the hob and the heat pump for example. The configuration is chosen in the app at first start-up.
What if a product is out of stock on Amazon?
Get in touch through the contact page quoting the kit code: we will point you to an alternative that works with the rest of the set, so you do not have to hunt for an equivalent model yourself and risk buying a part that will not talk to the other devices in the kit.
Why buy on Amazon?
Purchase, delivery, returns and warranty are handled by Amazon: delivery times, returns and warranty are shown on Amazon when you buy. The kit is our own work: we picked parts that work together, plus the accessories you actually need to fit it.
