Google Assistant works with a myriad of devices and this expansion doesn’t stop since the tech world is getting more and more number of smart home products. New product categories are always get added to the list of support of Google Assistant and now also, this list is expanding more to accommodate new products.
According to the new developer documentation, Assistant will soon work with smart air fresheners and fireplaces. Furthermore, Heaters have also been added to this list. So, Assistant will be able to turn fresheners on and off, and “adjust various modes and toggles” for the Fireplace as well.
For the heaters, the documentation reads,
"Heaters are similar to thermostats but do not support cooling and may not support setting temperature targets. Heaters may rely on modes, toggles, and fan speed settings."
Google Assistant, which is a virtual voice assistant works across more than 500 million devices, including smart speakers, phones, cars, TVs, watches, and more.
We will continue to update this list whenever a new product gets added to this list of support.
