The website talks about a “$13 Voice Assistant” a lot but the device they refer to the ESPHome Atom Echo seems to cost at least $30 everywhere i look, am i missing something?
Prices go up and down. It was probably that cheap when the article was written.
It was $13.50 a piece when I bought it:
But it seems to be out of stock on their website
