Receive and store Telldus weather station radio messages
This project is still work-in-progress.
Telldus weather station consists of
- Outdoor unit, which is like SwitchDoc Labs WeatherRack2 without light and UV sensors
- Indoor unit Telldus-FT0385R with pressure, humidity and temperature sensor and a display
This program receives messages and writes weather data to pywws database (CSV files).
Outdoor unit sends Manchester encoded message with 433Mhz radio OOK.
As Telldus weather station indoor unit receives a message from the outdoor unit, it sends 3 radio messages
- Oregon-WGR800
- Oregon-THGR810 or Oregon-PCR800
- Telldus-FT0385R
Requires
- Arduino Nano
- 433Mhz Receiver
- Arduino IDE for compiling and installing "telldus-weather-receiver.ino"
- Python3 sudo apt install python3-pip sudo pip3 install pyserial sudo pip3 install pywws
Create a data dir with weather.ini (see https://pywws.readthedocs.io/en/latest/guides/weather_ini.html)
