Tested with companies such as Elenia, Vantaan Energia Sähköverkot Oy, and Kymenlaakson Sähköverkko Oy for the compatibility of HAN port equipped electricity meters.
Please check your electricity distribution network company's website for detailed information on supported electricity meters and their nationwide replacement schedules.
Cozify HAN is a WiFi- and Ethernet enabled electricity consumption and production surplus reader. Additionally to supporting cordial WiFi antennas mounted also to outside of electrical cabinet, it can connect to a network using an RJ45 Ethernet cable if a wired Ethernet connection is available.
Cozify HAN is due to be released during 2025 Q1 and available via select electric product retail outlets and electricity providers in Finland, as well as through Cozify Shop.
Pre-order Cozify HAN now from the first limited production batch - the pre-orders will be shipped in Finland by the official launch date projected during 2025 Q1!
Discover the real-time electricity consumption of activities such as watching TV, running a washing machine cycle, or charging an electric car.
Usage costs Standby costs
Find out how much your devices consume in standby mode and what it costs you on a daily, weekly, and monthly basis.

Ensure an even distribution of your home's fuse usage. Shift the load to less-used phases if needed, i.e. when your electric car's charging phase approaches its maximum capacity.
Learn which devices in your home waste electricity and how much surplus energy your solar panels produce.
Track real-time consumption and surplus production, and see the costs at a fixed hourly rate or with a variable market electricity price.
Real-time consumption and surplus production Consumption and surplus production history
The HAN application provides real-time data on your home's consumption or surplus production, and it also gathers daily historical data for up to a month, including both consumption and surplus production details.

Cozify HAN has been designed to be placed next to the RJ12 connected electricity meter.
The device can be secured next to electricity meter in an electric cabinet using a double-sided tape.
Cozify HAN can be connected to a modern electric meter with a HAN port. The HAN port needs to be activated first - contact your electricity network provider about it.
Your home’s electrical system is typically divided into three phases, each protected by a main fuse. Cozify HAN provides real-time data on the load of each phase (L1, L2, L3), allowing you to monitor phase-specific consumption. Through the Cozify HAN app, you can see if any phase is nearing its maximum load. If so, you can redistribute usage—such as shifting devices connected to your electric car’s phase to another less-loaded one—or schedule energy-intensive appliances at different times using a Cozify hub.).
Upgrading the fuse size in your connection can cost several hundred euros, while increasing the total connection size may require rewiring and cost thousands of euros.
With the Cozify HAN app, you can monitor real-time energy consumption changes every 10 seconds, displayed both in watts and euros. To check a device in standby mode, simply keep the app open, unplug the device, and observe the change in consumption after 10 seconds. The app will display the reduction in watts, as well as the cost savings per hour, week, and month—whether based on spot market prices or fixed rates.
Open the Cozify HAN app, which updates consumption every 10 seconds. Turn a device on or off, and observe the change in power consumption in the next 10-second interval. The app will show how much the consumption has changed in watts and calculate the cost per hour, week, or month—based on either spot market prices or fixed rates.
If, for example, your solar panels generate more electricity than your home uses, Cozify HAN will display this surplus in real-time. You can see both the excess energy produced and how much you're saving based on spot or fixed energy prices.
By connecting Cozify HAN to a Cozify smart hub (ION / HUB / ZEN / DIN) with an active Premium subscription, you can automate devices to make the most of your surplus energy. For instance, you could schedule your water heater to turn on via a smart socket or relay, or initiate electric car charging using a switching relay, all while you have surplus production.
You can use any kind of standard WiFi 2.4GHz wired WiFi antenna for outdoor use. Cozify HAN comes with a standard compact mountable WiFi antenna. Use wired WiFi-antenna or Ethernet RJ45 connection (also supported by Cozify HAN) if you need improve connection / coverage outside your electrical cabinet.
Make sure your WiFi is using 2.4GHz network mode. It's also possible to connect your Cozify HAN via Ethernet cable for a wired connection. Simply connect your Cozify HAN with Ethernet cable to your local home network / router when you are adding the device in the mobile app, by choosing "Pair with Ethernet-cable instead" in the pairing process.
Optimize energy consumption by controlling devices according to the hourly exchange electricity spot price.
Controlling home heating and air conditioning based on the spot-price of exchange electricity is easy to implement with the Cozify system even for a summer house.
Everyone knows that a good night's sleep is very important. One of my favorite smart home automations is its benefits during the dark hours of the night combined with a gentle awakening the next day.
I decided to make a blog series about the benefits of the smart home, possible misconceptions and security. Through my blogs I will show, using examples, how a smart home really does make life easier and brings security night and day, whether we're home or not.
