How to ask Alexa for my sensor values?

I have sensors around my home on Wemos D1 Mini boards and Echo devices in almost every room.

Is there a method to ask Alexa for a sensor value? For example, "Alexa, what is the temperature in the basement"?

I've looked at the skills builder and am completely lost. If I have to build a skill for the device, how do I start? Is there any "Alexa Skills for Dummies" tutorials anywhere that doesn't require an advanced degree in AWS?

Is Alexa Gadgets Toolkit what I want to study?

Has anyone done something similar that can get me started?

When I was looking at it, I concluded gadgets was the way to go. I gave up and turned Alexa off permanently before I made any real progress though.
