Hi, @o-lukas

We have seen that several OCF devices don’t update their status in the API but it’s shown in the app because saving it in the API is intentional, not something that is done automatically for this kind of device. As you mentioned that the commands are being sent correctly, if you’re working on a personal project, you can have your own control of the latest status for this device.
