Power sensor reading in Amazon Echo/Alexa

Hi,

I have a power sensor configured that’s showing the current power usage/production of my appartment. I’d like to get the current value using an Amazon Echo Show and the normal speakers by asking something like “Alexa, what’s the current power state?”. If I understand the Alexa integration correctly, the only sensor type that’s currently supported is the temperature sensor. Does someone have an idea if that’s possible?
