Smart Dummy Switch

I have a question that may not be able to be answered here, but I will give it a shot. My home was built when switched outlets were all the rage. I have since taken all of the outlets off the switches, but now all of my rooms have switches that control nothing. I had purchased a few Moes branded smart switches and put them in, without a switch leg, only the hot and neutral legs coming into the switch. These worked great, I just set up an automation to have that switch toggle my lamps. The switches I bought have since been discontinued, so I purchased the new version of it, and it will not work without having a light/device connected to the switch. My question is: Is there a resistor or something of the likes that I could connect to trick the switch into believing that it is connected to a light?
Thank you!

Side Note: It is a two gang box, with another switch for the ceiling fan. I want to have something actually inside the box, not just over it.

Yes there is. They are often called a “load correction device”. They are for ensuring a small amount of current flows when using “no neutral” dimmers with LED lights.

e.g. GH Load Correction Device by Greenhse Technologies

Thank you! I will give it a shot!
