Ask HN: Indoor air quality sensors and other IoT that's local-first and not DIY? 4 years ago

I have an Airthings Wave Plus [1] which measures CO₂, Radon, VOCs, and some others but until recently I could only get the data out via the cloud integration.

Home Assistant recently added a BLE integration [2] with the device and it works great, way better than the Airthings app actually. So now I'm automatically logging and tracking all the data on a regular basis instead of hoping the app is still running in the background on my phone and updating the cloud.

I am not sure about initial setup since I had to go with the cloud integration to get it working in the first place a year or so ago, but maybe now you could skip that and just start reading the data off the BLE? It's possible but I cannot say for sure.

Stockholm parents built their own school app, then the city called the cops 5 years ago

This should probably link directly to the article: https://www.wired.co.uk/article/sweden-stockholm-school-app-...

Google says Nest’s built-in mic not listed in specs was not meant to be secret 7 years ago

I use a z-wave smoke detector to supplement the wired smoked detectors in my house: https://www.amazon.com/gp/product/B00KMHXFAI

I then paired it with https://www.home-assistant.io/ to send alerts to my phone, google home, etc.

Haven't had to actually test that the carbon monoxide alarm works yet because testing that is hard/expensive, but for smoke it works just fine.

Show HN: Fnm – Fast and simple Node.js version manager built in ReasonML 7 years ago

Yup came here to say this, although I have recently had issue with the Fish Node Manager which had me revert to using nvm.

Issues which made it unusable completely every time I tried to use node it could no longer find the node/npm binaries.

Pose: A declarative motion system for HTML, SVG and React 8 years ago

So because you don't have a specific use for it means no one does?

WhatTheFont – Shazam for Fonts 9 years ago

Since that page doesn't seem to be loading, here is a gist with the relevant bookmarklet. You click it once to turn on Fount, click a piece of text on the page, and it will show you in the top right the font-family, font-size, etc. (as it actually rendered on your machine vs. what the CSS says it should do):
