Minor Update: New OregonV3 Meter Models and Patch for rtl_433

The Oregon Scientific V3 series has been a popular choice for weather stations and other environmental monitoring devices. Recently, new models from 2023/2024 have been released, including UNNI and Newentor. However, these new models have a different sensor ID, which can cause issues with decoding the data. In this article, we will discuss the new OregonV3 meter models and a patch for rtl_433 to support these new devices.

The new OregonV3 meter models have a different OSV3 sensor ID, which is denoted by the second nibble of the sensor ID. The new sensor IDs are:

  • 0xf024
  • 0xf224
  • 0xf424
  • 0xf824
  • 0xfa24

These new sensor IDs are different from the previous models, which can cause issues with decoding the data. However, with a small patch to the "oregon_scientific.c" file, we can support these new devices.

To support the new OregonV3 meter models, we need to make a small patch to the "oregon_scientific.c" file. The patch is as follows:

654 	int sensor_id=	(msg[0] << 8) | msg[1];
new:
+655	if ((sensor_id & 0xf0ff) == 0xf024) {
+656		sensor_id = ID_THGR810 ;
+657	}

This patch checks if the sensor ID is 0xf024 and if so, sets the sensor ID to ID_THGR810. This allows the new OregonV3 meter models to be decoded correctly by rtl_433.

With the patch in place, we can now decode the data from the new OregonV3 meter models. The decoded data is as follows:

{"time":"2025-03-11 15:03:39","model":"Oregon-THGR810","id":82,"channel":1,"battery_ok":1,"temperature_C":8.3,"humidity":61,"data":"f8240254380016a44c","mod":"ASK","freq":432.93206,"rssi":-0.10952,"snr":37.26347,"noise":-37.373}
{"time":"2025-03-11 15:03:39","model":"Oregon-THGR810","id":82,"channel":1,"battery_ok":1,"temperature_C":8.3,"humidity":61,"data":"fa240254380016a64a","mod":"ASK","freq":432.93206,"rssi":-0.10952,"snr":37.26347,"noise":-37.373}
{"time":"2025-03-11 15:04:10","model":"Oregon-THGR810","id":82,"channel":1,"battery_ok":1,"temperature_C":8.3,"humidity":61,"data":"f0240254380016ac34","mod":"ASK","freq":432.93206,"rssi":-3.49197,"snr":31.66252,"noise":-35.1545}
{"time":"2025-03-11 15:04:10","model":"Oregon-THGR810","id":82,"channel":1,"battery_ok":1,"temperature_C":8.3,"humidity":61,"data":"f2240254380016ae32","mod":"ASK","freq":432.93206,"rssi":-3.49197,"snr":31.66252,"noise":-35.1545}

As we can see, the decoded data includes the model, ID, channel, battery status, temperature, humidity, and other relevant information.

In conclusion, the new OregonV3 meter models have a different sensor ID, which can cause issues with decoding the data. However, with a small patch to the "oregon_scientific.c" file, we can support these new devices. The decoded data from the new OregonV3 meter models includes the model, ID, channel, battery status, temperature, humidity, and other relevant information. We hope this article has been helpful in understanding the new OregonV3 meter models and the patch for rtl_433.
Frequently Asked Questions: New OregonV3 Meter Models and Patch for rtl_433

A: The new OregonV3 meter models are a series of weather stations and environmental monitoring devices released by Oregon Scientific in 2023/2024. These devices have a different sensor ID, which can cause issues with decoding the data.

A: The main difference between the new and old OregonV3 meter models is the sensor ID. The new models have a different OSV3 sensor ID, which is denoted by the second nibble of the sensor ID. The new sensor IDs are:

  • 0xf024
  • 0xf224
  • 0xf424
  • 0xf824
  • 0xfa24

A: You need to patch rtl_433 to support the new OregonV3 meter models because the new sensor IDs are not recognized by the default rtl_433 code. The patch allows rtl_433 to correctly decode the data from the new OregonV3 meter models.

A: To patch rtl_433, you need to modify the "oregon_scientific.c" file to include the following code:

654 	int sensor_id=	(msg[0] << 8) | msg[1];
new:
+655	if ((sensor_id & 0xf0ff) == 0xf024) {
+656		sensor_id = ID_THGR810 ;
+657	}

A: The benefits of patching rtl_433 to support the new OregonV3 meter models include:

  • Correct decoding of data from the new OregonV3 meter models
  • Ability to monitor and track data from the new OregonV3 meter models
  • Improved accuracy and reliability of data from the new OregonV3 meter models

A: There are no known risks associated with patching rtl_433 to support the new OregonV3 meter models. However, it is always recommended to back up your code and data before making any changes.

A: The patch for rtl_433 is specifically designed to support the new OregonV3 meter models with sensor IDs 0xf024, 0xf224, 0xf424, 0xf824, and 0xfa24. It may not work with other OregonV3 meter models.

A: You can find more information about the new OregonV3 meter models and patch for rtl_433 on the Oregon Scientific website or by contacting their support team.
