I saw this plug on Amazon:
https://www.amazon.it/funziona-Assistente-Funzione-temporizzazione-richiesto/dp/B075W91N3D
(sorry for the Italian page)
It says: " it works with Amazon Alexa, Google Assistant and IFTTT".
I can assume that I could use it with HA as a normal switch (without Alex, GA or IFTTT) ?
