we are now literally saving about €20/ week for some of our users with our optimiser. That means hardware ROI is 5w at current state.

The feeling when you’re building something and get more and more convinced we are building GUUD stuff.

@0xCoops Yes this is real. Over €1100 a year savings.

Picture a cloudless spring day in California. Millions of solar panels are at peak efficiency, but grid operators are frantically hitting the kill switch, shoving pure energy straight into the dirt. Why? The grid has no brain. 🧠👇

Quick update on today's Office Hours! We're pushing today's session at 14:00 to Friday next week at 16:00 due to scheduling constraints - apologies for the short notice! But to make it up to you, we're dropping a short video from our CEO Fredrik Ahlgren - consider it a little something while you wait. And actually, we liked the idea so much that we're gonna try to make it a monthly thing going forward. More on that soon. 👀 Had a question ready for today? Drop it in the comments and we'll make sure it gets covered during next week's session. See you there!

How Our Battery Optimizer Actually Thinks! Every 15 minutes, our optimizer wakes up, looks 24 hours into the future, considers everything it knows, and solves a math puzzle: "What's the cheapest way to keep the lights on?" It's less "buy low, sell high trader" and more a very patient accountant who rechecks the math 96 times a day and refuses to spend a single cent without a good reason. Read the blog post by our CTO @T0bias0lss0n and find out how it works (in great detail), why it sometimes makes decisions that look wrong to a human, and where it's headed next. Link in comments....

We have released this into the wild since few weeks back. It’s actually really good. Don’t trust me. Trust our users which many have switched from other systems.
