Flagship project
Cafein Your Palm
The café, under control. More time for what matters.
Lighting, sockets, the coffee machine, the refrigerator, and backup power — from one app.

The coffee runs. You stay with people
Economy
Less spent on power and on doing it by hand.
Ease
One tap from the phone.
Calm
Mains, generator, and power alerts.
More time
For guests, the room, and the business.
More than automation
Let the equipment work, and you stay with people
The system takes the café routine: lights, sockets, the coffee machine, the refrigerator, the sign, and the switch to the generator. You stay with the guests.

More time for guests
Home Assistant
The café runs itself
Home Assistant sits in the café, on site. The shift, the supply, and the generator proceed on their own: the staff waits, they do not press through a sequence.
- The coffee machine on its ownAt 7:30 it turns on to warm up before opening. At 21:15 it turns off if the shift forgot.
- After the generatorThe generator starts and gets time to warm up. Then the lights, the grinder, and the blender come on, and only after them the coffee machine.
- Start the day, end the dayTwo ready scenes on the screen: open the shift and close it.
- A plain control screenCoffee machine, lights, sign, refrigerator, grinder, blender, music, tablet, and outdoor light. Large buttons, the state is visible at once.
- The figures in one placePower on the main input and the coffee machine, internet speed, generator voltage and power.
- Hours and oilThe generator’s hour counter and the oil life: how much of 20 hours is used, and when the first change is due.






A steady infrastructure
