Translations:Controller hardware revisions/1/en
The definition of the revision
In the latest firmware versions, revision can be viewed in the web interface of the controller, Devices => System, channel system/HW Revision. Programmatical determination of the revision of the controller is possible via MQTT. If there is no such section in the interface, the controller can be identified by marking on the bottom side of the board (under the cover on the side of the DIN rail).
