Having trouble to read results

[Tarnakarlslund]

Excuse me for not understand, but i have the rpi_rf installed on my HA, but i dont know how to use it.
What do i have to do to read what RF devices the integration has found on my system ??
I have a lot of RF devices in my home that i want to control from HA and i also have a Telldus Hygrometer that i want to use in my bathroom to control the fan.
Is there any easy way to read the remoter values from a Nexa remote or any other brand in HA ?
Does it exists a Card thats easy to download to HA that also can control the rpi_rf and making it easy to integrate products in to automations ?
In my rpi_rf folder it did come up a new folder named "pycache" with 2 files, "init.cpython-310.pyc" and "switch.cpython-310.pyc" but i dont know how to use them or read them.
I think that the solution with adding a RF transmitter and reciver to the GPIO pins on RPI is a great idea because i dont want to buy different hubs and having dozens of hubs thats just doing 1 thing.
I did buy earlyer a Sonoff RFBridgeR2 but havent got anything working on that and when i find rpi_rf i instantly wanted to try that instead.
Great job on this integration, and if this work with Telldus/Tellstick products you deserves the Nobel price because the shops sell Telldus products that needs to be connected to a hub thats not anywhere to find or buy!
