🌦️ Best rtl_433 Compatible Weather Stations and Wireless Sensors
12 AcuRite, Ambient Weather, Ecowitt, ThermoPro and La Crosse stations and sensors compared, for feeding local weather data into Home Assistant with an SDR.
✅ 12 Picks Reviewed
✅ 433 vs 915MHz Explained
✅ rtl_433 and Home Assistant Notes
✅ Sensor-Only Options
Most consumer weather stations and wireless thermometers talk to their displays over simple, unencrypted sub-GHz radio: usually 433MHz in AcuRite gear and many budget sensors, and often 915MHz in US Ambient Weather, Ecowitt and some La Crosse models. Because these broadcasts are open, an RTL-SDR running rtl_433 can decode them and publish every reading to Home Assistant over MQTT, with no cloud account and no extra hub.
This is part three of our 433MHz and sub-GHz smart home series. If you do not have a receiver yet, start with our RTL-SDR dongles for rtl_433 guide. If you would rather build your own sensors, see our temperature and humidity sensors for embedded devices guide. Every product below has an Add to Cart button and was checked against its live listing; frequencies are quoted only where the listing states them.
💡 Reality check before you buy: rtl_433 support depends on the exact sensor model, not the brand, so check the model on the sensor’s label against the rtl_433 supported devices list before you buy. Frequencies vary by region: the same brand may sell 433MHz, 868MHz and 915MHz versions (Ecowitt lists all three), and one RTL-SDR can only listen to one band at a time. Many listings do not state the frequency at all; we say so where that is the case. Cheap sensors broadcast openly, so your neighbours’ sensors will appear too; filter by device ID in Home Assistant. Mount wind and rain sensors safely, keep clear of power lines, and use proper outdoor-rated mounting hardware.

🔍 How to Choose a Weather Station for rtl_433
📻
Know the frequency
Your SDR and rtl_433 config must match the sensor band. AcuRite listings here state 433MHz; the TempPro TX-2B states 915MHz; Ecowitt sells 433, 868 and 915MHz versions.
🔎
Check the model list
rtl_433 decodes by protocol. AcuRite 5-in-1, AcuRite 6045M and Fine Offset family sensors (Ambient, Ecowitt) are well covered; always confirm your model.
🧩
Station or sensor only
If Home Assistant is your display, a sensor-only listing like the AcuRite Iris 5-in-1 saves money and clutter.
🌧️
Rain and wind needs
Full arrays add wind and rain; simple thermometers only report temperature and humidity. Haptic rain sensors avoid moving parts but can be less precise.
🔋
Power and placement
Most sensors run on AA or AAA batteries; the WS90 is solar powered. Place arrays in open air, away from walls and roofs that skew wind and temperature.

❓ Frequently Asked Questions
Do I need the weather station’s display if I use rtl_433?
No. rtl_433 reads the outdoor sensor’s broadcast directly, so a sensor-only listing such as the AcuRite Iris 5-in-1 is enough. You will want the display only if you like a screen on the wall. See our RTL-SDR dongles guide for the receiver.
Which frequency should I set rtl_433 to?
Use the frequency on the sensor label or listing. Most AcuRite gear in this guide is 433MHz (433.92MHz in rtl_433), while many US Ambient Weather, Ecowitt and some ThermoPro sensors use 915MHz. If you have both, use two dongles or rtl_433’s frequency hopping option.
Will I see my neighbours’ sensors too?
Probably. Sub-GHz sensors broadcast openly and can reach a few hundred feet, so rtl_433 often logs nearby stations, tyre pressure sensors and doorbells. Note your own device IDs and only create Home Assistant entities for them.
Is a Wi-Fi weather station better than rtl_433?
Wi-Fi consoles are simpler and many have official Home Assistant integrations, but some rely on the cloud. rtl_433 is fully local and works with cheap sensors without Wi-Fi, at the cost of running a Raspberry Pi or PC with an SDR.
Can I build my own weather station instead?
Yes. An ESP32 with a BME280 or BMP390 covers temperature, humidity and pressure; see our barometric pressure sensors guide. Wind and rain sensors are the hard part, which is why many makers buy an AcuRite or Ecowitt array and read it with rtl_433.
