I am running OpenHAB 3 on Raspberry Pi. I would like to connect some weather station senders (temperature, humidity; I know how to decode the binary messages) and 433 Mhz power switches to openHAB.
What is the easiest way to do that? From what I understand, these options are available:
- via exec binding (send code with RF433 tool; receive with some RF tool/script)
- via MQTT binding with a wifi-microcontroller+RF receiver/sender (Tasmota flashed) as briefly mentioned here: How to receive Temperature and Humidity from 433 MHz Weather Station
- via RFXCOM binding possibly(?) with a 433 MHz receiver attached to the Raspberry GPIO RFXCOM - Bindings | openHAB
All of these methods do seem to require a lot of time to figure out how they are implemented in detail. Which way would you recommend?
