I would like to implement the following (The hardware is not a problem, but the integration into openhab 2):
I want to measure the room temperature with a small Attiny and transfer it to openHAB (Raspberry pi) using 433mhz. For example, the data should be displayed graphically.
Because I turn off my Fritzbox from time to time I cannot transfer the measurement data via WLAN. In addition, the Attiny and the 433mhz enable me to achieve a significantly longer battery life than with WLAN devices (e.g. ESP8266).
So my question:
How can I integrate the measurement data from Attiny into openHab2 using 433mhz? Unfortunately I have not yet found a way to integrate measurement data from my own sensors into openHAB.
Thanks for your help and ideas
