A Shelly 1 Gen3 relay wired into the motorised gate's control unit gives the open pulse from your phone, at home or away. The Shelly BLU contact on the gate tells you whether it is open or shut, and the 4-button BLU remote replaces the old radio handset. It is run from the Shelly app, with no hub.
What it does
- The Shelly 1 Gen3 closes its contact for an instant on the control unit's command input, as the push-button or the remote would.
- From the Shelly app you open the gate at home or away; with Matter you can also control it from Apple Home, Alexa or Google Home.
- The Shelly BLU Door/Window contact on the swing leaf or the sliding leaf reports whether the gate is open or closed.
- The Shelly BLU RC Button 4 remote has four keys: one for the gate, the others free for lights or other Shelly commands.
- The Shelly 1 Gen3 picks up the signals from nearby BLU devices and brings them into the app, acting as the gateway.
- If the gate is left open after someone has gone through, a notification lands on your phone.

Before you order
Do you need a hub?
No. The Shelly 1 Gen3 connects to the home Wi-Fi and also acts as gateway for the kit's Shelly BLU devices, that is the contact on the gate and the remote. Everything is managed from the Shelly app.
Will it work with my gate?
It works with motorised gate control units that have a volt-free command input, like the one for the wall button or the key switch: almost all of them. The Shelly 1 Gen3 does not replace the control unit or the motor. If in doubt, send us the model of the control unit from the contact page.
Does it work with Alexa, Google and Apple?
The Shelly 1 Gen3 is Matter-compatible: it is added to Apple Home, Alexa and Google Home as a switch. The BLU contact and the remote are managed in the Shelly app, which also offers the voice assistant integrations.
Do you need an electrician?
Yes: the relay is wired into the gate control unit and given a supply. Work on 230V must be carried out by qualified personnel, with the installation isolated. The BLU contact and remote, on the other hand, you fit yourself, with double-sided tape and a button cell.
What happens if there is no internet?
The BLU remote still drives the relay locally, and the gate always opens with the original remote and the wall push-button. Without internet, though, you cannot open from the app when away and you get no notifications.
Are batteries included?
The BLU contact and the BLU remote each take a CR2032 coin cell, as the product names say; whether it is already fitted is stated on the Amazon listing. The relay runs off the mains and uses no batteries.
Can I add devices?
Yes: more BLU remotes for the family, a second relay for the pedestrian gate or the garage door, Shelly sensors and lights. The Shelly 1 Gen3 acts as the gateway for the BLU devices nearby.
What if a product is out of stock on Amazon?
Get in touch through the contact page quoting the kit code and the product you cannot find: we will point you to an alternative that works with the Shelly app and the Gen3 relay, so you keep a combination we have checked and you do not have to hunt for an equivalent model yourself.
Why buy on Amazon?
Purchase, payment, returns and warranty are handled by Amazon, as with any other order on the site. The kit is our own work and we checked that the parts work together; delivery times, returns and warranty are shown on Amazon when you buy.
