Onvis recently announced a new smart plug with Matter and has now made it available for pre-order in the US. This smart plug differs from most of the recently announced Matter-certified smart plugs in that it uses Thread instead of Wi-Fi. Thread is considered far superior to Wi-Fi and is the preferred communication protocol for Matter-certification.
The Onvis S4 Smart Plug is currently on sale as part of their “Early Bird” pre-release promo. They are offering 40% off the regular retail price for US customers who purchase in advance. The 2-Pack is listed at $24.99 right now (MSRP US $39.99), and the 4-Pack is listed at $39.99 (MSRP US $64.99). The 4-Pack makes it just $9.99 per smart plug. For fans of Thread (and how could you not be a fan of the speed & responsiveness) that is a huge savings for a smart plug featuring Matter over Thread. At the moment, the Eve Smart Plug (the other Matter Smart Plug featuring Thread) is listed at $39.99 for just 1.
If you are interested in the Onvis S4 Smart Plug featuring Matter over Thread, you can preorder it on their website.
