For industrial units and warehouses where the lights stay on in empty areas. Two DIN rail Shelly Pro 2 modules drive the contactors of four lighting zones, the Shelly i4 Gen3 picks up the department buttons and the LAN switch links everything to the company network. Schedules, switching on and off from the app, from the buttons or with automatic scenes.
What it does
- Each of the two Shelly Pro 2 units has two channels: together they drive four contactors, one per lighting zone.
- The Shelly i4 Gen3 reads up to four department push-buttons and, over the network, switches the matching zone on or off.
- At the end of the shift the zones switch off on a timer; anyone still on the floor switches their own zone back on with the push-button.
- The DIN-rail Shelly LAN switch wires the two Pro 2 units to the company router.
- In the app you see which zones are on and can switch them all off with one command, off site too.

Before you order
Do you need a hub?
No: the Pro 2 units connect to the company network by cable through the switch included, the i4 Gen3 over Wi-Fi. Everything is managed with the Shelly app and the devices' web interface, with no extra gateways.
Why switch the contactors and not the lamps?
The lighting circuits in an industrial unit draw heavy currents and are already run by contactors in the board. The Pro 2 units drive the coil, which draws very little: the lamps stay wired as they are today and the power side of the installation does not change.
Do you need an electrician?
Yes. The Pro 2, the i4 Gen3 and the wiring to the contactor coils are all at 230V inside the board: the work must be done by qualified personnel, with the installation isolated, to the manufacturer's diagram.
Does it work with Alexa, Google Home or other systems?
The devices run from the Shelly app, which also offers integration with Alexa and Google Home as the manufacturer describes. On business sites, Shelly devices can also send data to supervisory systems on the local network: ask your own engineer or get in touch via the contact page.
What happens if there is no internet?
The actions between the i4's buttons and the Pro 2 units travel over the local network, so they carry on working without internet, as do the schedules saved on the devices. All you lose is control from off site and the notifications.
Can I add more zones?
Yes: each extra Pro 2 adds two zones and another i4 adds four more buttons. The switch has free ports. Get in touch through the contact page with the number of zones and the lighting board diagram.
What if a product is out of stock on Amazon?
An item can sell out or change version. Get in touch through the contact page quoting the kit code: we will point you to an alternative that works with the other devices and with the same app, so you keep a combination we have checked and you do not have to go back over anything yourself.
Why buy on Amazon?
Purchase, payment, delivery, returns and warranty are handled by Amazon, as with any other order: 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 needed to fit them.
