From One Tinkerer to Another — Welcome to Elewatt

If you've ever stayed up past midnight watching electricity price graphs and wondering why your water heater runs at peak hours — this platform was built for you, by someone exactly like you.

Hi, I'm Reedik. By day I'm a developer. By night (and often into the early hours) I'm the person who built Elewatt — a platform that connects to real-time electricity spot prices and automatically controls your smart home devices to run when electricity is cheapest. Not because someone hired me to. Because I genuinely needed it myself and couldn't find anything that did the job properly.

How this all started

Like most home automation stories, mine started with a spreadsheet. I was trying to figure out the actual cost of running my water heater — not the spot price you see on Elering's dashboard, but the real all-in price including network fees, renewable energy charges, excise duty, and VAT. Nobody showed that number anywhere. So I built something that did.

Once I had the data, the next question was obvious: why is my water heater running at 8am when electricity costs four times more than at 2am? So I connected a Shelly smart plug. Then another one. Then a relay for the heating. Then I wanted to add my EV charger. And suddenly I had Elewatt.

Who this is for

You don't need to be a developer to use Elewatt. But it helps if you're the kind of person who installs their own smart home devices, reads the manual for fun, or gets genuinely annoyed when a "smart" device isn't actually smart about energy.

• →You have a water heater, EV charger, home heating, floor heating, or washing machine that could run during off-peak hours but doesn't
• →You're on an exchange-rate electricity contract (spot price) and actually want to benefit from the price swings
• →You've already got (or are curious about) Shelly smart plugs or relays — or you want to add a new device to the platform
• →You like things that are transparent, honest, and don't lock you into anything
• →You want to lower your electricity bill without complicated setups or monthly subscriptions

What's connected right now

The platform currently supports automating these devices through Shelly smart plugs and relays:

More devices are being added. And I mean that literally — you can suggest the next one. There's a form on the site specifically for that. If enough people want a particular integration, I'll build it. That's how this platform grows.

No strings, no surprises

Elewatt is a DIY platform. It's not a subscription service with a free trial that auto-charges you. It's not a corporate product with a support ticket queue and a 5-day response time. It's something I built, maintain, and keep improving — and I genuinely want to hear from the people using it.

You set it up yourself. You stay in control. If you want to override a schedule, you override it. If you want to understand exactly why a device turned on at 3am, the data is right there. No black boxes. No magic. Just automation that does what it says it does.

Ask Reedik — yes, actually me

There's a page on the site called "Ask Reedik". It's exactly what it sounds like. You ask something, I answer. Not a chatbot, not a support team, not a template response — me, personally, reading your question and writing back.

I want Elewatt to be the kind of platform where you feel comfortable asking "this is probably a stupid question, but…" — because there are no stupid questions, and the person reading it has definitely asked the same thing at 1am while staring at a circuit diagram.

So if something doesn't work, something's confusing, or you just want to know if your specific setup is supported — ask. I'm here.

Try it. Break it. Tell me what's missing.

The best thing you can do for Elewatt right now is try it. Create an account, connect a device, see how it handles price automation for a week. If something feels off, clunky, or missing — that's genuinely valuable feedback and I want to hear it.

You can use the test credentials on the features page to explore without setting anything up yet. Poke around. See if it makes sense for your home.

And if you're building something interesting with smart home automation and want to talk shop — reach out. That's kind of why I built this thing in the first place: to find more people who care about the same problems I do.
