This project contains a Home Assistant integration for 433MHz wireless temperature and humidity sensors based on the Nexus protocol.
Receiving of the sensor's wireless signals is via a CC1101 radio connected via SPI, using the CC1101 Linux Driver and Python interface.
The Nexus protocol implementation is based on the rtl_433 decoder.
The integration has been tested using the Bresser 7000020 sensors. According to the rtl_433 decoder, the following devices should also be supported:
- FreeTec (Pearl) NC-7345
- infactory/FreeTec (Pearl) NX-3980
- Solight TE82S
- TFA 30.3209.02
