Years ago i discovered the RF-protocol of the Davis Vantage Vue ISS Weather station (see Davis Vue Hacking – Part 1 and Davis Vue Hacking – Part 2)
I used an Moteino to receive and decode the data. But the moteino lacks of IP-Support and i used a Gateway to bridge the serial output from the Moteino to MQTT.
Now i wanted to get rid of this setup and have an All-In-One sollution. Therfore i used a RFM69 Board and an ESP32 and wired both together with seven wires, added some programming and now ist is up and running since some weeks.
You'll find the source-code and some documentation on in the github repository. https://github.com/dcbo/ISS-MQTT-Gateway
You'll need only an ESP32 and an RFM69 Board.
The Wiring is documented in the Repository.

It all fits in small Box.

Have the hardware wired up and ready to go. But receiving many errors from the build command after updating the Platformio.ini file with my info.
Would really like to get this working with my Davis 6263 system.
If someone could help out an old guy, would rally appreciate it.
Thanks
