Philips (Signify) released the Skylight this June, a big "artificial window" ceiling panel. It ships with no smart connectivity whatsoever: no Hue, no Zigbee, no Matter, no app. Just a proprietary remote. For that price that felt ridiculous, so I took it apart.
Turns out it speaks Bluetooth SIG Mesh. I wrote a small mesh stack in Python, provisioned a Raspberry Pi as a node in the lamp's network, and bridged it to HA over MQTT.
Working: on/off from HA, so it's in my automations. Here it is triggered by a motion sensor: https://www.instagram.com/reel/DbLMPRmtqbh/
Not working (yet): brightness, colour and the presets. Those go through a proprietary Telink vendor model and I haven't cracked the opcode. All SIG models are bound but only on/off actually drives the LEDs and I think it needs a firmware dump off the Telink chip.

Happy to help if anyone else has one of these.
