About Kalmnest
Technology you don't notice
Kalmnest comes from the Den Bosch area and has a real love for Home Assistant. Our own home is our test lab: from an alarm clock that starts with a sunrise to a car that learns by itself when to charge.
Smart technology is only valuable when it feels natural. That's why we choose local connections where possible, systems that you stay in control of, and that will still work five years from now.
Frequently asked questions
What if the internet goes down?
Then part of it keeps working. Lights, sensors, switches and routines that are connected locally carry on. Connections through a manufacturer's cloud, such as the car, energy prices and some cameras or vacuums, wait until the internet is back. Where possible, I choose a local connection.
Do I have to do everything at once?
No. Many people start with lighting or energy and expand later. Everything we build fits into the bigger picture afterwards.
Which brands can be connected?
Home Assistant works with thousands of brands, such as Philips Hue, IKEA, Shelly, Tesla, Somfy, Roborock and most smart meters, inverters and home batteries. During the consultation we look at what you already have.
What happens to my data?
As much as possible in your own home. Camera footage and usage data are stored locally. Some devices, such as a car, always work through the manufacturer's server. We explain that up front.
Does it work with my solar panels and home battery?
Almost always. Most inverters and batteries, such as SolarEdge, Enphase, SMA, Growatt, Huawei, GoodWe and Victron, can be connected. Sometimes locally, sometimes through the manufacturer's app. We look at what you have during the consultation.
Is a home battery still worth it when net metering ends?
That depends on your usage, your panels and your energy contract. With a dynamic contract and smart control a battery can pay off more. We work it out honestly with you, even if the answer is that it doesn't pay off (yet).
Does it work with cars other than Tesla?
Yes. Smart charging works with most electric cars and chargers, such as Alfen, Easee, Zaptec and Wallbox. Sometimes through the car, sometimes through the charger.
