YDrip – An open source water meter that detects leaks
Hi HN, I'm developing an open-source water meter for Home Assistant and thought the HN community might be interested. I've been using some version of it after a few costly toilet leaks that my city meter missed. Recently, I decided to polish it up so others could use it. It might also function as a gas meter reader (https://youtu.be/9Dso4EBAoiE), but this is still experimental. The device runs on 3 AA batteries and utilizes an ESP32-S3. It works by measuring the spinning magnet inside the brass housing. It stays in deep sleep until it needs to transmit usage or leak…

In plain words
YDrip is an open-source water meter designed for Home Assistant that detects leaks by measuring the spinning magnet inside a standard meter's brass housing. The device, powered by an ESP32-S3 and three AA batteries, stays in deep sleep until transmitting usage or leak data. It targets homeowners seeking to catch water leaks their utility meter misses, offering both water meter and experimental gas meter reading capabilities. The hardware performs rotation counting and leak detection to minimize battery drain.

You don't need to adopt new tools for LLM observability2024 · github.com · ▲102If you've built any web-based app in the last 15 years, you probably used something like Datadog, New Relic, Sentry, etc. to monitor and trace your app, right? Why should it be different when the app you're building happens to be using LLMs? So today we're open-sourcing OpenLLMetry-JS. It's an open protocol and SDK, based on OpenTelemetry, that provides traces and metrics for LLM JS/TS applications and can be connected to any of the 15+ tools that already support OpenTelemetry. Here's the repo: https://github.com/traceloop/openllmetry-js A few months ago we launched…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
