Question 1

Which smart home system provides the biggest savings on my electricity bill?

Accepted Answer

For a standard home, we recommend systems like Plejd or Wiser. By automating your heating, scheduling exterior lighting, and integrating controls with current spot electricity prices, you can eliminate energy waste and cut costs by up to 20%, without compromising on comfort.

Question 2

Do I need to tear open the walls and run new wires for a smart home?

Accepted Answer

No, and that is the major advantage! Today's smart home tech, such as Plejd, uses small wireless 'pucks' installed completely out of sight behind your existing light switches. You keep your current switches and walls intact, but instantly gain app control and scheduling capabilities via Bluetooth.

Question 3

How much does it cost to make the entire house smart?

Accepted Answer

The beauty of modern systems is their supreme scalability. You don't have to buy everything at once. You can start by automating your outdoor lighting and living room for a very reasonable cost (especially with the ROT tax deduction). Then, you can easily expand the system room by room whenever you choose.

Question 4

Will the lights still work if the internet goes down?

Accepted Answer

Yes, absolutely. This is why we recommend professional systems over cheap Wi-Fi bulbs. Our installed systems communicate via their own secure Bluetooth mesh or dedicated radio protocols. Furthermore, your physical wall switches will always function perfectly, regardless of your router's status.

Question 5

Can I voice-control my home using Google Assistant or Apple HomeKit?

Accepted Answer

Yes, it is incredibly simple. By installing a small Gateway connected to your router, we bridge your smart system to the internet. From there, you can seamlessly control your home's lighting, heating, and outlets using simple voice commands via Google Home, Alexa, or Apple HomeKit.

Question 6

What should I do in case of an electrical emergency or power outage?

Accepted Answer

Safety first! If your RCD (jordfelsbrytare) trips repeatedly or you smell burning plastic, do not touch anything. We offer 24/7 emergency electrical services across Greater Stockholm with fast response times. Our certified electricians will secure your electrical system and fix the fault immediately to minimize the risk of fire or property damage.

Question 7

Which electrical installations provide the biggest savings on my energy bill?

Accepted Answer

The fastest ways to lower your energy costs are installing smart home controls (like Plejd) and upgrading to energy-efficient LED lighting. By scheduling your heating and lighting according to spot electricity prices, you can reduce energy waste by up to 20%. We handle all types of electrical work, from smart homes to safe EV charger installations.

Question 8

Can I use the ROT deduction and Green Tech deduction at the same time?

Accepted Answer

Yes! When we install an EV charger, we apply the Green Technology deduction, giving you a 50% discount on both materials and labor directly on the invoice. For other general electrical work in your home (like upgrading a fuse board), we deduct 30% of the labor cost via the ROT deduction. We handle all the paperwork with the Swedish Tax Agency for you.

Question 9

Why is it important to hire a certified electrical company?

Accepted Answer

Faulty wiring is one of the leading causes of house fires. Smista Elinstallation AB is a fully authorized electrical contractor approved by the Swedish National Electrical Safety Board (Elsäkerhetsverket) with over 30 years of combined experience. This guarantees a safe installation, valid warranties, and the official documentation often required by your insurance company.
