ESPHome RF Receiver too much noise

I’m trying to build an RF re-transmitter using ESPHome on a D1 mini. I have a 315MHz remote (FCC ID T99058404300) for my fireplace that I’m trying to essentially “clone” so that it can be operated over wifi with home-assistant.

All of my hardware looks correct:

• Wemos D1 mini ESP8266
• 315MHz receiver (and transmitter, but I’m not that far into using it yet)
• Tried both USB power and a good 5v universal AC/DC switching PSU

Following the instructions for RF devices, I’ve come up with the following configuration. Everything seems fine, except there’s way too much noise if I’m looking at raw data (so much output that it’s unreadable). The rc_switch data is randomly coming in slowly, but doesn’t seem to be related to when I’m pressing buttons on the remote that I’m trying to read signals from.

Has anyone successfully set up a ESP8266 to read signals from random RF devices without so much noise so that you can find the correct signals to replicate?

Here’s my current config, pretty much copy/paste from the docs linked above
