Product features
Smart control from the switchboard, switches untouched
Pro relays install at the switchboard, so the smart layer lives in one place instead of scattered through wall boxes around the house. Every wall switch stays exactly where it is and keeps working the way it always has; the relay adds app control, schedules and automations on top. It's the tidiest way to make a whole house smart without changing a single thing the family touches.
Installed at the board, not in wall boxes
Every existing switch keeps working
One location for your electrician to service
DIN rail and Ethernet, like the rest of your board
The Pro series mounts on a DIN rail alongside your breakers and adds an Ethernet port, so control traffic can run over cable rather than Wi-Fi. Multi-channel models switch several circuits from one unit, and the form factor is one your electrician already knows. Everything the compact relays do, schedules, scripting and local control included, is here too.
DIN-rail mount
Ethernet plus Wi-Fi
Multiple circuits from one unit
Runs blinds and shutters, not just lights
Switch the two channels into cover mode and the relay drives a shutter, blind or awning motor instead: one channel up, one channel down, with calibrated position control so you can send it to exactly half open. Power metering tells the relay when the motor hits its end stop, so calibration is automatic.
Calibrated position control
Works with standard AC shutter and awning motors
One device per motor
See what every circuit really uses
PM models meter their own output, so you can watch live power draw and review consumption history per channel in the app. That's enough to find the appliances quietly costing you money, confirm the hot water or pool pump actually ran, or catch a heater someone left on. Set thresholds and the relay can act on them itself, switching off a load that draws too much for too long.

What is a Shelly relay?
A relay is a switch you never see. It wires into the circuit between the supply and the light or appliance, so that circuit can be switched from the wall, from your phone, from a schedule or from an automation. The switch already on the wall stays wired in and keeps working for anyone who just wants to flick it.
The channels
One channel per circuit
Channels decide how many you buy. The range runs from one to four, so a single light takes a one-channel module and a plate driving two circuits takes a two-channel. Each channel switches its circuit independently.
The two homes
Wall box or switchboard
The smaller modules sit in the wall box behind an existing switch, where the constraint is the space left behind the mechanism. Pro units clip onto DIN rail in the switchboard instead, which is where whole circuits and three-phase work belong.
The metering
What PM on the end means
A PM model measures the load it is switching and reports power and accumulated energy alongside the on-off state. Models without it switch only. The specifications on this page tell you which one you are looking at.
The control
It runs without the internet
Schedules and scenes are stored on the relay and run there, so the light still comes on at dusk when your connection is out. Every unit serves its own web interface on your network with no account, and Shelly publishes its local API, which is why Home Assistant ships an official integration.
Getting started
1
One circuit at a time The usual start
Most people begin with a single module behind the switch they use most, often the lounge or the outside light. The plate and the wiring stay as they are, and that one circuit becomes something you can schedule or run from your phone. Add the next one whenever you feel like it.
2
The whole switchboard at once Or start at the board
When the board is already open for a rewire, a new build or a switchboard upgrade, Pro units on DIN rail cover several circuits from one place. They run the same firmware and the same app as the in-wall modules, so a house can mix the two freely.
Nothing has to be settled up front. Each relay works on its own, there is no hub to buy first, and you can start with one circuit and go as far as you like from there.

Which relay do I need?
Gen3 is the value pick and does everything most homes need. Gen4 adds Zigbee and Wi-Fi 6, and Matter is on out of the box, so it joins Apple Home or a Zigbee network with no hub in between. Pro is DIN rail hardware for the switchboard.
If you run the Shelly app or Home Assistant over Wi-Fi and just want a reliable relay behind a switch, save the money and buy Gen3. Pay the difference for Gen4 if Matter or Zigbee matters to your setup. One thing to know: Zigbee on Gen4 is an either/or mode, so a relay switched to Zigbee leaves Wi-Fi entirely. And if you're searching for Gen2, it shipped under different names: the Plus and Pro ranges.

Behind the switch
Fits in the wall cavity behind an existing switch or power point. The switch on the wall stays and still works; the relay sits behind it and makes the circuit smart.
In the switchboard
Clips onto the standard rail in your switchboard, next to the circuit breakers. Keeps everything in one serviceable spot, which suits whole-home installs and bigger jobs.

Yes. Pro models wire into the switchboard, which is licensed-electrician work in Australia. For a sparkie it's a familiar job: the unit clips onto the DIN rail like any other module.
In the switchboard. Pro models mount on a DIN rail alongside your breakers and add an Ethernet port for wired control, which is the right shape for whole-home and multi-circuit installs.
Yes. Switch it to cover mode and the two channels drive a standard AC shutter, blind or awning motor, with calibrated position control.
