Gain control, be energy smart

Smart DIN Relay

Imagine always having someone who looks out for your electricity consumption and allows you to become energy smart. Someone who doesn’t want you to waste time controlling home appliances separately, but lets you control them in groups.

Now that’s a frient!

Gain smart control of your home appliances

With the smart relay mounted on your DIN rail, you can switch on and off anything connected to an electrical circuit of your home remotely. Depending on the electrical circuits of your home, you can for example turn off the heating while leaving other groups of appliances turned on.

All you need is to have the Smart DIN Relay connected with your DIN rail and your smart home hub. The Smart DIN Relay includes overload and temperature protection.

WARNING: Electrical equipment should only be installed, accessed, serviced, and maintained by qualified electrical personnel.

That's what frients are for

Remote control of appliances connected to an electrical circuit

Tracking your electricity consumption

Connecting with your DIN rail

The friently electricity spy

As if it’s not enough that you can control appliances connected to an electrical circuit, you can also track their electricity consumption.

Check how much electricity your refrigerator and freezer consume. Or how about your lights and heating? This friently spy wants to give you these insights to help you lower your consumption and save money.

It’ll also disclose any abnormal behavior of your appliances, such as a sudden spike in consumption that could be a sign of a defective appliance.

Arrive at a warm and cozy cabin

You’ll no longer arrive at a cold cabin during the wintertime. With this frient, you can turn on the heating a few hours before your arrival and get comfy right when you get there.
