Unrelated to this (and sorry for highjacking this topic), but just want to say a big big thank you to ladyada for founding Adafruit. When we decided to go fully open source hardware at AirGradient, I looked at the ‘business’ models of two c

Is it only me or are you guys also being disappointed when a very interesting article is heavily AI written? I feel like not wanting to read it in depth, even though the topic is unique and something I like to learn more. It’s a shame becau

It’s actually a nice article if it wouldn’t be so obviously AI written. In my opinion this really devalues the reputation I am having for a publication and is a pity especially in this particular case as home assistant is such a great commu

I guess for a lot of the Show HN posts, people could accuse of being Ads. This was an honest account of my experience coding this. If you do a bit of research on our company, you might come to a different judgement. But obviously everybody

Different strategies. - sometimes when it’s lost, just roll back. Commit very often. Sometimes it’s getting lost on simple and easy features - very unexpectedly. - prompt regularly to review the architecture and clean up the code, check for

I actually think this could be the completely wrong approach. By focusing on only one persona, you might focus on one that for reasons NOT covered in this questionnaire does not work out. Practical example from us at AirGradient. Initially,

100% agree. It is super important to know the composition of the particles. Unfortunately currently only super expensive instruments can measure this in real-time. This is why I believe contextual information will become much more important

Achim from AirGradient here. Great to see this posted. When we first heard about this new sensor, we were quite pessimistic about its performance but have been pleasantly surprised by its performance. It is something we consider now for pot

You can use an air purifier. The Hepa filters are effective in eliminating PM. Gases like NO2 and VOCs can be reduced with carbon filters. Make sure that your carbon filter is large and different get saturated too quickly.

Yes of course! Thanks for pointing it out. I corrected the above.

What’s important to understand is that PM2.5 is not PM2.5. It only defines the diameter of the particles but can be composed of very different elements. From salt that dissolves in the lungs to toxic metals. Currently it is extremely diffic

Achim from AirGradient here. Some thoughts on this. Purely focusing on the display, I can see a certain logic to say: Display not working => Not recommended. And probably I chose the wrong title for this as it made the article too much f

Yes, I did not mention our outdoor monitor being featured because I don't see this as a success when I critique the whole methodology of the review. As I mentioned above, we are working on a refresh of the indoor monitor. The display i

A few thoughts from me on the discussion so far, which I find incredibly insightful. Many thanks to everyone sharing their perspectives. I truly appreciate it. On subjective reviews: I think there's absolutely nothing wrong with review

No, this is actually the purple air indoor monitor which has no display.

Agree. I actually tried to reach out to Louis Rossmann a few times but haven’t got a response (yet). I think what’s most interesting is that we figured out a business model based on open source hardware that’s sustainable. Thus a win-win fo

Achim from AirGradient here. Good to see that my post has been submitted here. Happy to answer any questions you might have. I spend quite a long time writing this post and it actually helped me to see the bigger picture. How much can we ac

We went full in and not only open sourced the firmware of our air quality monitors but made it completely open source hardware, this means it includes the electronic schematics, enclosure files etc. [1] I believe it was the single most impo

We don’t have enough experience with the SEN5x yet to give an opinion but it’s definitely a good sensor. It might be better than the Plantower but on the other hand we know the Plantower really well now after 10s of thousands of units going

Hahah. Thanks for calling me! We actually have a sample of the Bosch in our office but haven’t come along to test it yet. Maybe with this call, I will get our team onto it. The form factor has pros and cons in my opinion. The size and lower

Achim, founder of AirGradient here. This article is super interesting as it shows that one of the key features (showing air pollution as cigarettes equivalent) on the new AirGradient Open Source Map [1] is actually scientifically backed. Th

Nicely produced video but two things I think make it less great. 1) The sponsorship / advertisement is artificially linked to the content of the video and makes it more like an ad for the computer. It appears like the video is optimize
