I have a dimmer (Jung 1731DD) which is mainly operated manually, but I would like to switch this dimmer on in case I’m not at home. This dimmer can be switched on/off using a pulse signal (relay on for 100ms). To make this work I have a Shelly 2.5. One port is used as pulse relay (shelly is configured to automatically switch off after 0.1s). When providing a pulse one does not know whether the pulse switched the dimmer on or off. In order to “read” whether the dimmer is on or off I use the other port of the shelly (always on) to feed the dimmer and measure the power consumption of the dimmer, see below.
Now I would like to make an entity that sends payload: “on” when to toggle the dimmer and use the power consumption reading to determine whether the dimmer is on or off, as if it is an ordinary light entity. How can I do that?
