Aetherfield shows what your AirGradient air-quality monitor is measuring, right now and over time. It reads the monitor directly over your own Wi-Fi: no account, no subscription, and nothing about your home leaves your home. An AirGradient cloud account is optional, for monitors on another network.
- User manual — adding monitors, reading the numbers, history, settings
- Privacy policy — short version: the app collects nothing
Aetherfield is an independent app. It is not made by, affiliated with, or supported by AirGradient, so please send questions about the app to me, not to them.
Requirements
- iPhone or iPad with iOS or iPadOS 17 or later
- An AirGradient ONE (indoor) or Open Air (outdoor) monitor with firmware 3.0.10 or later, on the same Wi-Fi network — or an AirGradient cloud account for monitors elsewhere
- No monitor yet? Tap Try sample data to see the whole app working with made-up readings.
- Free. No account, no ads, no in-app purchases.
Common questions
No monitors are found. This is almost always the Local Network permission. Open the device’s Settings → Privacy & Security → Local Network and turn Aetherfield on. Also check the monitor and your device are on the same Wi-Fi (not a guest network). Adding the monitor by IP address skips discovery entirely.
A monitor stopped updating. The tile keeps its last reading and shows when it arrived. Check the monitor’s power and Wi-Fi; a signal weaker than about −70 dBm causes timeouts.
There are gaps in the history chart. Local history is recorded only while the app is open, and the chart shows a break rather than inventing a trend nobody measured. Cloud monitors use AirGradient’s own continuous record.
The cloud says my token was rejected. Make sure it’s a long-term token and that API access is enabled for that place in the AirGradient dashboard.

Questions, bug reports and suggestions are welcome. Email norm@sohl.com. I’m one person, so it may take a few days, but I read everything. It helps to say which device and monitor model you’re using.
