Two Shelly Plus RGBW PM controllers drive the 12/24V LED lighting in the cabin and the cockpit, with switching, dimming and scenes from the Shelly app. The existing switches on board stay in use thanks to the Shelly Plus i4 DC, and two BLU Button Tough Bluetooth buttons go where no cable reaches.
What it does
- Each Shelly Plus RGBW PM handles four channels: four dimmable white light lines or one RGBW strip, with consumption metering.
- The Shelly Plus i4 DC reads up to four push-buttons already fitted on board and turns them into commands: on, off, dim, call up a scene.
- The two BLU Button Tough buttons are battery-powered and wireless: one in the cockpit and one by the berth, for example, to switch everything off without getting up.
- In the Shelly app you build scenes such as "night", with low light in the cabin, or "all off" when you leave the boat.
- On a schedule the cockpit lights come on at sunset and go off at a set time, even when you are on the mooring.
- The lights' consumption shows in the app: useful for seeing how much they cost the service batteries.

Before you order
Do you need a hub?
No. The Shelly modules connect straight to the on-board Wi-Fi and the BLU buttons talk over Bluetooth to the Shelly Plus modules. You do need a Wi-Fi network on board: an on-board or 4G router, or the marina Wi-Fi. The router is not part of the kit.
Does it work with Alexa and Google?
Yes, with the Shelly skill for Alexa and the Shelly integration in Google Home: you switch the lights on and off and dim them by voice, as long as you have a smart speaker and an internet connection on board. The modules also work in Home Assistant.
Do you need an electrician?
Yes. The modules wire into the 12/24V on-board system, each with its own fuse, and to the existing lights and push-buttons. It is a job for a marine electrician or other qualified personnel, done with the batteries disconnected and following the manufacturer's diagram.
What happens if there is no internet?
If the on-board Wi-Fi stays up, the push-buttons and the scenes keep working locally. Without internet you lose the app from a distance and the voice commands. If the router goes off altogether, the BLU buttons and the wired push-buttons are still connected to the modules.
Can I add more lights?
Yes. Each RGBW PM has four channels: if you do not use them all, you already have room to grow. For further zones add another Shelly module or more BLU buttons, which appear in the same app. For deck lighting or other loads get in touch through the contact page.
Are batteries included?
The BLU Button Tough buttons are battery-powered: what comes as standard is stated on the product's Amazon listing. The Shelly Plus modules have no batteries; they run off the 12/24V on-board supply.
What if a product is out of stock on Amazon?
It happens, above all with multipacks. Get in touch through the contact page quoting the kit code and the item that is missing: we will point you to an alternative that works with the rest of the set, so you can finish the order without changing the other parts.
Why buy on Amazon?
Purchase, payment, delivery, returns and warranty are handled by Amazon: delivery times, returns and warranty are shown on Amazon when you buy. The kit itself is our own work: we picked parts that work together, plus the accessories needed to fit them.
