over a year has passed since Yeelight announced their HomeKit compatible Bluetooth Mesh Gateway, and whilst it has been available in China for a while now, it didn’t appear for purchase on any of the usual international reseller stores, until very recently. Now the gateway has surfaced on Amazon.com for just under US$33.00, along with two of the three current bulbs that also work with the hub.
If you’re unfamiliar with this device, in simple terms, it is a hub for Yeelight Bluetooth and Bluetooth mesh lighting products to connect to one another, as well as get them exposed to HomeKit. Bluetooth mesh, for want of a better description, is the Bluetooth version of Zigbee, whereupon the Bluetooth network is spread like a net, to constantly expand the Bluetooth network as you add more devices. This helps alleviate the issue with Bluetooth having a rather limited range.
It also has the added benefit of not clogging up your wifi network, as only the hub itself uses a WiFi connection, and in fact, also comes with an ethernet port for a stable wired connection to the network. The hub is capable of supporting up to 100 devices, which not only includes the Yeelight’s Bluetooth mesh bulbs it’s designed for, but also regular Bluetooth devices from Mijia, like the E-ink temperature sensors, for example.
Currently, Yeelight has three Bluetooth Mesh bulbs as part of the M2 collection, along with a series of Bluetooth Mesh bulbs released prior to the launch of the gateway. The M2 series, which consists of an E27 bulb, a downlight, and a spotlight, are all capable of warm to cool whites. However, it should be noted that whilst the hub, along with the downlight and spotlight are available on Amazon.com, these products don’t appear to be sold via the official Yeelight store. *Furthermore, if you’re in the US, even though the gateway can work with 110-240v, the bulbs are listed as only being able to work with 220-240v, so will not work. It may be that these bulb work with both 110-120v and 220-240v, but I’m awaiting clarification on this from Yeelight, so it’s not advisable to buy at this time unless you’re from the EU, or a region that supports 220-240v of course!
*Update: Yeelight has confirmed that the current series of bulbs that work with the Yeelight Bluetooth Mesh Gateway are only available in 220-240v variants, with no 110-120v versions available at this time.
