www.communityairsensor.orgCommunity Air Sensor Workshop 2025The Community Air Sensor Workshop was created to continue the critical discussions and knowledge-sharing around emerging air sensor technology, especially in light of the cancellation of the U.S. EPA Sensor Workshop 2025. While that event will no longer take place, our virtual workshop provides a collaborative space for experts, organizations, and community members to exchange best practices, explore innovations, and advance air quality monitoring. Through interactive sessions, hands-on workshops, and open discussions, we aim to empower communities with accurate, accessible air quality data—driving innovation and informed decision-making for a cleaner, healthier future. This event is completely free and organized entirely by volunteers who are passionate about advancing air quality monitoring and making sensor technology more accessible. Our goal is to ensure that knowledge and collaboration remain open to all, without financial barriers. We appreciate the dedication of our organizers and contributors, whose efforts make this workshop possible.

The latest release of the #AirGradient firmware removed the code that phones home to the company servers even when you check the to to explicitly tell it not to do so. This is a big win for #privacy and #SelfHosting!

I plan on flashing this onto my device and testing it to verify nothing was missed. #tcpdump and #wireshark are my friends. 😄

This doesn't have anything to do with the #HestiaPi (yet 😉), but AirGradient is one step closer to fixing their compilation instructions.

This is exciting news because once their code is modified to stop phoning home to the company's server, I plan on adding documentation to the HestiaPi project on how to configure the #AirGradient ONE to act as a remote temperature and humidity sensor.

If you've ever had a #thermostat mounted too close to the door, you understand why this is important.

If you're also considering a filter, a CR box is a great DIY option that has been proven to be just has effective or better than some of the fancy $400 ones. cleanaircrew.org/ufaq/does-the

For outdoors, there are a variety of open data maps you can use from local air quality monitors regarding fires and quality.

Always check local ordinances around whether you can start a fire before burning anything on your property or when camping and hiking. Some grounds may require that you keep a fire extinguisher on you. Make sure you are familiar with how to report a fire and have a plan to evacuate during no burn periods.

For folx considering air quality monitors following the LA fires. A few months ago I purchased an Air Gradient One for indoors due to fires near my hometown. You can use the code "SABP13ET" for 10% off (SmartHomeJunkie). It's open source, homekit compatible, and hackable, but also works well out of the box. You can view historical data from web view on your phone or laptop. Having a monitor allowed me to determine if an air filter was necessary from the fires and on the day to day reminds me to air out the room from CO2 build up or from running my stove, even when out of the house. The discounted DIY model was as easy to build as three pieces of legos and a few screws. airgradient.com/indoor/

Other monitors I considered from reviews on reddit where the HotKrem 5-in-1 and TemTop M2000c on the more affordable end. I also considered mainstream competitors like Air Things, Purple Air, and Govee. I decided that the price was not worth the performance, though there are plenty of people who are satisfied with their purchase.
