Smart home installation on the Côte d'Azur, for properties you're not always in
A smart thermostat, a camera and a few sensors let you keep an eye on a Riviera home from another country. You don't need an expensive system. You need devices that work reliably and an app you can use from home.

The second-home context
Which smart devices earn their place in a Côte d'Azur second home?
This page covers the devices: thermostats, sensors, cameras, plugs and hubs, most of which fit into your existing wiring. For a wired system tying the whole house together, or motorising the shutters, see our home automation guide.
A thermostat with frost alerts. The coast rarely freezes, but the arrière-pays does in January. An empty house inland, especially one with exposed pipes, is at risk in a cold snap. Set a connected thermostat to 8°C frost protection and have it alert you if the temperature falls below that. The same alert tells you when the heating has failed.
Remote heating and cooling. Switch on the reversible heat pump two hours before you arrive and the house is comfortable when you walk in.
Shutter control. If your shutters already have motors, a compatible hub can close them through the hottest summer hours (roughly 1pm to 4pm) and again at sunset.
Alarm and cameras. You get a notification if someone breaks in and can look at the camera feed. Pair them with a smart lock or gate opener and you can let a cleaner in from abroad.
For the rest of the departure checklist (ventilation, water isolation, insurance clauses), see preparing your Côte d'Azur second home for a long absence.
The law
Is a programmable thermostat compulsory in French homes?
Yes, from 1 January 2030 for existing homes. The deadline was 2027 until a decree of December 2025 pushed it back; 2027 now applies only to new builds. The heating has to be programmable and regulated room by room, or zone by zone. It needs comfort, reduced, frost-protection and off settings.
A connected thermostat isn't required. A basic programmable system meets the rule. You're exempt if fitting one isn't technically and economically feasible, for example when the payback would take more than ten years. Stoves you feed by hand are also outside the rule.
Heating controls fitted by a firm in a home over two years old are taxed at 5.5%, with no RGE (state-approved installer) condition. That holds for a second home too. Some room-by-room systems also earn a small CEE (energy-supplier) grant.
System options
Zigbee, shutter hubs or Matter: which smart device standard fits your home?
Most smart devices talk wirelessly, but not all in the same language. The standard you pick decides which devices can join later. A wired KNX system is a different job, covered in our home automation guide.
Zigbee and Z-Wave
Wireless standards built for retrofits. Devices pass signals to each other and to a central hub, with no new wiring. Zigbee is open and widely supported. Both get through thick walls with repeaters.
Shutter and blind hubs
The usual way to automate shutters and blinds in France. The hub works with the motors it was made for and may link to other smart home platforms. Ask the installer which motors it controls.
Matter
The cross-brand standard backed by the big voice-assistant and device makers. Devices from different makers work together. It's still maturing, but it's the sensible label to look for when buying new wireless devices.
Budget
What adds to the cost of smart devices in a Riviera second home?
Signal is the hidden extra. Thick stone walls stop wifi and Zigbee, so a large or old house may need repeaters or mesh wifi. Ask the installer to test the signal in each room before quoting.
What's already fitted counts too. Shutters that already have motors need only a hub, while manual ones need motors first.
Get two written quotes that name each device and the hub, and say who sets up the remote alerts for you.

How does smart home technology work differently in France?
UK
Some UK smart thermostats are sold in France, but French electricians rarely fit them, so check you can get local service. Heat pump makers here have their own connected controls, which link straight to their units. Ask which one your unit supports. Shutter hubs have no real UK equivalent.
US
The main voice assistants and smart home apps work in France, and the big two take French commands too. Check that each device you buy supports the one you use. US smart switches and dimmers won't fit: they're made for American wall boxes. Buy switches from European suppliers so they fit French boxes and standards.
Germany
KNX (an open wired standard that works across makers) is common in Germany, and KNX certification is the same across Europe. German-made KNX switches work in French homes.
Choosing a contractor
What should you look for in a smart home installer on the Côte d'Azur?
Any competent electrician who knows your chosen system (a shutter hub, Zigbee devices, a connected thermostat) can fit wireless devices. Experience counts for more than a certificate here. Ask to see similar installs, ideally in homes like yours.
Ask whether the installer can diagnose problems remotely. An installer who can fix a dead sensor online saves you a trip from abroad.
Ask what happens if the manufacturer's servers go down. Many apps route everything through the maker's cloud. If the company drops support, the device can stop working. Devices that also run locally, or fall back to local control, last longer in a house you'll own for decades.

Questions
Frequently asked questions about smart home systems on the Côte d'Azur
If your question isn't here, send it with your request and we'll answer it directly.
No. For existing homes the date moved to 1 January 2030. The 2027 date now applies only to new builds. A basic programmable system meets the rule.
It depends on what you want to control. Shutters and blinds need a hub that works with your shutter motors. Heating needs a thermostat that suits your boiler or heat pump. For lighting, pick switches that fit French wall boxes. Zigbee devices work anywhere in Europe. For new devices, look for Matter, a cross-brand standard backed by the big voice-assistant and device makers. Ask whether the system works with the voice assistant you already use.
Yes. Wireless devices need no new wiring: smart switches fit the existing wall box, smart plugs go in existing sockets. The usual problem is signal. Thick stone walls block wifi and Zigbee, so budget for a repeater or mesh wifi. Ask the installer to confirm your heat pump model works with a thermostat before you buy one.
Only when a firm supplies and fits it in a home finished more than two years ago. Heating regulation and programming equipment is on the energy-improvement list at 5.5%, with no RGE condition. Buy the thermostat yourself in a shop and you pay the standard 20% on it. Ask for the reduced rate on the devis.
You lose remote control and alerts until the line is back. Many apps also run through the maker's cloud, so some devices stop altogether. Devices that also run locally keep following their schedules. A 4G router that takes over when the broadband drops keeps the alerts coming. Ask the installer which of your devices need the internet to work.
