Pluggable parts, as easy as LEGO. -
40+ Creations
Join a community, build on their shoulders. -
Complete control
With open source code you can understand what you are bringing into your home. -
€ Affordable
You could build this entire home for the price of one Nest thermostat.
How does it work?
The best technology the community has to offer.. hidden from view.
← The main controller
The beating heart is designed to be hidden, for example, inside a fake candle.
Create a network of sensors →
Measure and control light, temperature, air quality, electricity, and so much more. We like hiding them in books.
The main controller
Go beyond the glowing blue orb. For example, by hiding it inside an LED candle. It can act as a normal light, or notify you of the system's status.
The controller
Good looking things are a pleasure to use.
-
Control with your phone or laptop.
A good looking web-based interface and an app which can only be accessed inside your home.
-
Automation flows
Create automations using a simple drag-n-drop interface.
-
Your house should not be online
Go cloudless. Outside remote control is done via SMS, and tied to your phone number. Simple, secure.
A wealth of secure sensors
-
ELECTRICITY USE
Track your use by counting the lightpulses on your electricity wheel. See how you are saving power. -
SMART THERMOSTAT
Precise per-room heater control, and auto-shutdown when nobody is home, is built into the controller. -
TEMPERATURE AND HUMIDITY
Create a comfortable climate, and feed the smart thermostat. Bonus: also predicts the weather. -
DUST SENSOR
A laser powered fine dust sensor. Let it automatically turn on an air filter when things get dusty. -
CO2 AND CO SENSOR
Avoid waking up with a headache, or not at all, by keep an eye on CO and CO2 levels. -
PLANT HEALTH
Check if your plants have enough water, and turn on a warning light if they don't. -
SMART LOCK
Unlock the door for people who know the password. Useful for elderly care. -
DISCONNECT THE NET
Not home, or asleep? Disconnect your home from the internet. Makes hacking or leaking a lot harder.
Temperature, humidity and weather sensor
Measure temperature, humidity and air pressure over time. The air pressure allows the system to predict the weather, like an old school barometer. No need to connect to the internet for the weather prediction anymore!
The BME280 sensor
It's amazing what such a small thing can do!
This tiny sensor measures temperature, humidity and air pressure, all in one.
TIP: Why not organize a workshop, and create a large network or sensors in your neighbourhood.
Connecting the sensor
1First create the base sensor.
2The BME280 has 4 pins that you'll need to solder on. Two pins are for power, and 2 for the data signal. Connect..
- GND
GND
- VCC
VCC
- CLK
pin 8
- DATA
pin 9
3Finally, upload the code to the node.

The code is open source; you are free to use, modify and share it.
Electricity sensor
Measure how much electricity your house uses by counting the little light pulses that your meter gives off every few seconds. The more power you use, the faster this light blinks. Count the frequency, and bingo.
The photo diode
The little LED at the end of this board is actually a photo sensitive diode. It can respond really quickly, which allows it to detect the light pulses.
Use some tape or other construction to place the photodiode in front of the blinking light, and make sure not other light can interfere with the counting.
TIP: The sensors automatically form a 'mesh network': they pass along messages, so vast distances can be crossed.
Connecting the sensor
1First create the base sensor.
2Use 4 wires to connect the sensor to the base:
- GND
GND
- VCC
VCC
- CLK
pin 8
- DATA
pin 9
3Finally, upload the code to the node.
If necessary, tweak the diode's sensitivity by using a tiny screwdriver and turning the little metal knob.

Why it matters
Your data shadow
Are you listening to sad songs on spotify a lot? It could limit your job opportunities. Databrokers collect every bit of data to build, update and sell profiles about you that contain thousands of scores. This reputation increasingly influences your chances in life.
All data is credit data, we just don't know how to use it yet.
