Here is a few ideas:

Alexa enabled switch to turn on / off a TV using the IR blaster

my boss used 3 of these this to build a smart sprinkler system for his house.

Haha, we built this internally to use with Axiom scanners in our fulfillment centers which use RS232 interface, those scanners are 20 years old.

I convinced my boss to let me sell these as open source since we found many cool IOT uses for them around the office as well, that's why you are getting the RS232 on there but most people probably will not need that feature, but hey... it is there if you need it :)

Yes ESP8266 has WiFi Built-in but thanks for the pointer, I will update the description to reflect that fact.

we have more stock, just waiting to transfer to Amazon

Yes we probably design a case that you can 3D print and will add it to GitHub soon ish
