Controlling a dumb RF Remote via RTL_433

Hello,

I am trying to control some RF outlets that are normally controlled via an included RF remote over RTL_433. I have MQTT configured (outside of HA), and RTL_433 installed as an add-on.

Both are configured and all is communicating. I’m new to both MQTT and RTL_433.

My SDR dongle is picking up the button presses from the remote.
For reference, this is the device in question, bought nearly a decade ago.

I can confirm that the data from the remote is picked up by RTL_433 and published into MQTT. Below is the data from pressing the 6 different buttons.

Is there a way I can integrate this and control the device via RTL_433/MQTT?

RTL_433 only receives, does not send. You would need something like a Broadlink or a RfLink to send.

I use OpenMQTTGateway and an ESP + 433MHz transmitter for the same use-case
