Ceiling light as gateway for E14 mesh bulb

Hi Guys,

I’m a happy owner of several ceiling lights from Yeelight and also some BLE sensors from Xiaomi, which are connected via the BLE gateway functionality of the lamps.

Currently I’m looking for some E14 bulbs and came across the Xiaomi/Phillips bulbs (wifi), as well as the Yeelight BT Mesh bulbs.

Is it possible to use the BLE gateways as Mesh gateway aswell?
And does someone know the size of the E14 mesh bulbs? The Xiaomi/Phillip ones are pretty big in my opinion.

Ceiling lights can’t be gateway for MESH device.
