How to configure GPIO RF module?

Configuration
1

Hi,

I’m new to Home Assistant and I’m trying to figure out how to add generic RF transmitter to control RF outlets.

I have 433 Mhz tx module which is connected to gpio 17 and power outlet. I can control the outlet with rpi-rf python module on Raspbian, but I cannot figure out how to do the same on Home Assistant.

I read the documentation and understood rpi_rf module should do the trick, but I don’t know how to enable it: https://www.home-assistant.io/integrations/rpi_rf/

I edited the configuration.yaml according to these instructions: https://www.home-assistant.io/getting-started/configuration/

I added switch with rpi_rf platform, saved and verified the configuration and restarted the system, but nothing seems to happen. I cannot see any change in dashboard or anything else.

I’m sure this is a basic thing, but as a new user I’m not able to figure this out. Any help is appreciated.

Nevermind. It started working now. I guess restarting the server wasn’t enough and needed full power cycle. Anyway, now it shows in the dashboard with the same rpi_rf configuration I already tried and it controls the outlet.

I read from another thread that I would need to change my Home Assistant to something called Home Assistant Supervised and install there the same rpi-rf python module I have on Raspbian. However this was not necessary. I have only the Home Assistant with its own OS and rpi_rf is working fine without any extra installs.

It still doesn’t show up in devices list though. Also it won’t show up when creating automations. At least I can now control it from dashboard.

Hi @torx5

I am still struggling with getting this working. Like you first post I have no problems with rpi_rf on rasbian (buster). Both for transmit and receive so I am sure it is not a hardware problem. When I move to my RPI4 with HA OS I cannot get the transmission to take place (via a switch entity on lovelace).

Is there anything else you can suggest ? I have followed the documentation example e.g.

# Example configuration.yaml entry
switch:
  - platform: rpi_rf
    gpio: 17
    switches:
      bedroom_light:
        code_on: 1234567
        code_off: 1234568
