433MHz Receiver as sensors

Hardware
1

Hi I have,
433MHz Receiver and Transmitter connected to my Raspberry Pi

I have it successfully connected as Switch via https://home-assistant.io/components/switch.rpi_rf/ to toggle some Power A/C Switched, that works well. (But I do need to get bigger anthena )

But I also have few devices that send signals and I want to use them as sensors (button, temperature etc…)

How do I connect it to HASS? It seems you need to have gateway that connects it to events like https://github.com/1technophile/OpenMQTTGateway

My question is can I do this with my current HW on RP3? Has anyone tried this without 3rd HW Gateway ?

Thanks

I think the only way to do this at the moment is with pilight https://www.pilight.org which has a homeassistant component. Although I think you may need a dedicated RPI for it because processing the 433 is CPU intensive.
