for existing Raspberry Pi (next only RPi) is planned to use ZigBee.
It is possible connect e.g. Bosch Thermostat to RPi?
Where can be found technical data (requirements, technical info, etc.) for Bosch devices for right implementation to RPi, please?
@misa15 No, that‘s no possible. To use all features of the BSH devices it’s mandatory to use the BSH controller.
All BSH device will be assigned individually to the controller by unique QR code.
This is not completely true. Except for firmware updates the support in zigbee2mqtt* is basically there. So with a zigbee stick like the sonoff usb dongle you can connect the thermostat to a raspi - if said raspi is running zigbee2mqtt.
*should be there in the december version
