I integrated all my 433MHz devices by listening for them on a Sonoff RF Bridge (https://sonoff.tech/product/accessories/433-rf-bridge https://sonoff.tech/product/accessories/433-rf-bridge) which then pushes the signal to MQTT. From there it is easy to pick it up.
Generally speaking the main problem is the RF part (to be able to catch it somewhere, and reuse)
- Abishek_Muthian 7y agoI should have mentioned that I'm using RTL-SDR to catch the signal.
- BrandoElFollito 7y agoAnd how do you interface to it? Do you send what you caught to MQTT? I am considering having something else as the RF receiver but would need to forward what it received to MQTT (I can write that part myself - it is really the interface to the dongle I would like to understand)
- Abishek_Muthian 7y agoI use DVB-T USB dongle. You can use this project[1] to decode it. [1]https://github.com/merbanan/rtl_433 https://github.com/merbanan/rtl_433
