Door Lock

1. Install Z-wave
2. Install z-wave JS module
3. Add device -> How do you want to add your device -> Legacy Secure
4. Enter programming pin on lock -> 0

Philips Hue Lights

1. I configure all philips hue lights through zigbee directly connected to HA

hue lights support color_temp in mireds, here are some mired-kelvin conversions:

Kelvin	Mired
6000	167
4000	250
2600	385

Shelly

1. Outbound Websocket wss://homeassistant.reeseapps.com/api/shelly/ws

Shelly devices can act as "passive" or "active" bluetooth scanners. Both of these configurations allow home assistant to proxy bluetooth connections through shelly devices, significantly extending the range of your home assistant's bluetooth capabilities. Active scanning uses more power but is quicker to pick up and transmit device information. Note that "gateway mode" is not required, just enable bluetooth and rpc or select "active" from the configuration menu for the shelly device.
