Absolutely. Most smart switches support integration with voice assistants such as Amazon Alexa, Google Assistant, and Apple Siri.
You can simply say:
“Alexa, turn on the living room fan.” or “Hey Google, turn off the bedroom light.”
For users in the Middle East, UAE, and SA, an Alexa version that supports Arabic is available.
For users in India, voice assistants can be set to Hindi or English.
