Your phone is about to become your fuse box
Your phone already runs most of your life. We think the next thing it will run is your electricity, and that is why we are building Sidryn.
Most of us already run our lives from our phones. We bank on them, pay bills on them and buy prepaid units on them. Yet the part of the house that decides how fast those units disappear, the fuse box, is still a box on the wall that nobody looks at until something trips.
We think that is about to change. It is the reason we are building Sidryn.
The fuse box knows everything and tells you nothing
All the electricity in your home passes through your distribution board. It knows when the air conditioner is running, when the water heater has been left on and how much the fridge draws through the night. But it has no way of telling you. So when your units run out sooner than you expected, all you can do is guess.
Your phone can be the screen it never had
Phones have already become the remote control for much of the home: the TV, the gate, the security camera. Electricity is the obvious next step. When a unit beside your distribution board can measure each circuit and switch it on and off, your phone becomes the place where you see and control your power.
That is what we are building with Sidryn:
- See where it goes. How much each circuit uses through the day, and what that costs at your tariff. At the Band A rate of ₦209.50 per kWh, knowing which circuit is eating your units matters.
- Switch it from anywhere. Turn circuits on and off from the app, at home or away.
- Keep what matters on. Circuits you mark as essential are never switched off automatically.
Why this matters in Nigerian homes
Many homes juggle prepaid units, grid supply that comes and goes, and an inverter or generator in between. Managing that by hand is hard work. When you can see what each circuit uses, you can decide what to run while the grid is on, what can wait, and what is quietly wasting money.
Where we are
Sidryn is getting ready for product testing. We will share what we learn here as we go, including what works and what does not. If you would like to follow along, join our priority list.
