RF 433MHz transmitter AND receiver

I’m trying to find an off the shelf solution for my DC ceiling fan that has a 433MHz remote that works perfectly, but I’d like to be able to automate my fan through HA. I’ve been looking at the BroadLink RM4 Pro but it’s quite expensive for what I need it for. Plus, it doesn’t do what I want which is the device always listening for RF signals from the fan’s remote so that HA doesn’t get out of sync from the remote if u want to use that. I know I can use an ESP and wires and stuff, which I can do, I just don’t want the clutter of that, and having to source all of those parts, which in the north eastern of the US can be hard or having to pay a third of the cost of the device for shipping.

Thanks in advance for anyone who helps me find a solution
