WiFi Interference?

[-HammerHead-]

I built an OpenGarage device following the guide here: https://community.home-assistant.io/t/opengarage-open-source-wifi-garage-opener/17228. It works, except it seems to be causing some sort of interference with the remote. The remote works very intermittently after installation (sometimes have to press the button 7 or 8 times). The red LED on the side of the opener that lights up to show it’s receiving a signal is constantly blinking, even when the device is not connected to the opener (just powered on). After unplugging the ESP8266, the red light immediately stops blinking and normal functionality resumes. My opener is a LiftMaster and the remote is 318MHz. I don’t see how it would be interfering, but clearly something is causing an issue. Any ideas?

It’s actually a Linear opener…but it seems I can’t edit my post. My OpenGarage device is a couple feet away from the opener mounted on the ceiling. I’ve tried placing it all over on the ceiling (within 20 feet) and the issue persists.
