Great product!
It's not something you wish you needed to buy but it's a great product for sure. super easy to work with. great display, and I love that it sends the info to your phone. the app is very nice as well. connected without any hiccups and seemed very accurate. In this house, Safety is important so having this information was very helpful.

Works well, easy to read display, long battery life...
I'm quite impressed with this radon detector. While a bit bulkier than others, it is advertised to run for up to 7 years on 2 AA batteries. The display is clear, easy to read, and always "on" - it requires ambient light to read and doesn't timeout like on some other detectors I've purchased. The remote app is a bit confusing to initially pair with the device, but works flawlessly afterward. It's priced above its competition, but I feel it's worth the extra $$. Other Aranet detectors can be paired to the same app resulting in whole home environmental monitoring if you are willing to put out the funds.

Fast radon readings, easy to use app, home assistant support
Much faster readings compared to the original Aranet Wave, the e-ink screen is comfortable to look at and power efficient yet very capable. Pairing with the Aranet app via bluetooth is simple and easy, simply enter the app, tap the device and the screen will show a pairing code. Data loads quickly and the graphs are simple and easy to use. Supports data ingest into Home Assistant for custom ApexCharts cards like the one in the photo. Data is broadcast every 5 minutes. With the Aranet integration and a Bluetooth capable HomeAssistant node it detected the readings once "Smart Home Integration" was enabled in the Aranet app. Overall good value relative to the other radon detectors on the market and SAF makes a tidy, simple app. Note there is no cloud sync for this data, but the data stays on the phone it is synced with.

Buy It! It’s Phenomenal!
We’ve been concerned about the potential for high levels of radon in our basement. One of our neighbors told us his radon levels were reading well over 4.0 so he had to install an exhaust system. That led me to buy a test kit and send it in. I wanted something for continuous monitoring so I bought this. Not only is it very accurate, it’s wonderful to be able to track the history in the mobile app! Plus, the e-Ink display is genius. It’s very easy to read and requires very little battery power. I haven’t changed the batteries at all since I first set it up a few months ago. HIGHLY RECOMMENDED! One thing I learned is that the radon levels can be substantially higher than normal after rain or when the ground freezes. Radon is a gas and tries to find its way out. If the ground is wet or hard (or both), it has no where to go. Normal level in my basement is roughly 1.5 though this graph shows a bit higher - we’ve had a LOT of rain recently.

Excellent radon detector.
Good radon detector. Easy to use and the values are accurate, just need some time to get a good, averaged reading.

Nifty Radon Monitor Device
Neat Radon measurement device. It operates with two AAA batteries. The front LED display provides the current Radon level, the ambient temperature and relative humidity. There is a battery level indicator and a 3-segment radon level bar graph. It comes with an illustrated user guide. It has bluetooth connectivity and apps for remote readouts to smartphones, as long as you are within the theoretical 33 foot bluetooth range. It had fairly quick response to changing Radon levels. I have it sitting on the top of a bookcase about 4 feet below a forced air return vent. I can see the reading change when the furnace comes on first thing in the morning after being off overnight. The Radon level in the basement runs about 1.6 and any where from 0.6 to 1.6 on the main level.

The app doesn't have key feature
The detector itself is accurate and very well made. However, its app doesn't have 1 day, 7 day or 1 month rolling average history, unlike other detector. This makes the detector less useful if you consider how spiky the radon level data are. Please add rolling average capability in the app.

Parfait
Parfait ! Facile à utiliser et l application pour téléphone est intéressante. Elle fonctionne en bluetooth mais toutes les mesures de la journée sont restituées lors du retour. La courbe est colorée en fonction dans la dangerosité de la quantité de radon. Je ne regrette pas cet achat

Excellent radon monitor, Outstanding battery life and smart home integration
I've had this radon detector running continuously in my home for six months now, and honestly it's given me a real sense of peace of mind. Radon's invisible and it's a genuine health risk, so having reliable, real-time data instead of relying on occasional test kits has made a huge difference. One of the best things about this device is that it runs on two standard AA batteries. I don't have to worry about plugging it in or keeping it charged — just pop in some batteries and it works anywhere. And the battery life is impressive: after six months of continuous use, the battery level has dropped only 8%. At this rate, the advertised 7-year estimate looks about right. You genuinely set it up and forget it. What really made this purchase worth it was integrating it with Home Assistant. I've been pulling radon readings, temperature, humidity, and barometric pressure directly into my dashboard. The temperature and humidity readings have checked out well against my other sensors around the house, so it's not just the radon monitoring you're getting value from. Having all the data logged means I can track longer term trends and set up custom alerts — that continuous awareness is exactly what I was looking for. The e-ink display is clean and easy to read. The 10-minute measurement interval gives you a solid picture of radon fluctuations without being noisy. The unit is compact, well-built, and unobtrusive. For anyone who wants accurate monitoring and the peace of mind that comes with it, this is a strong pick.
