I finally had the opportunity to install the device for testing. The Sonoff light actuator is of course controlled with the in-house app eWeLink. This app can be linked to an existing Philipps Hue account. My lights can now all be seen and controlled from this app. Conversely, however, I can't see any way of controlling the Sonoff actuator in the Hue app or in the Apple Home app. I think it could work with the Matter version (green). However, this does not (yet) seem to be available from Digitec.
