Really depends what you want… however what I have been tempted to do recently is to take my old unit (which is a standard PIR sensing unit) is to use 2x remote relays…
1 which controls the power to the PIR (normal wiring as per instructions), and one which controls power straight to the light (most of the time, the feed to the bulb can be found inside the wiring box so easy to tape into, just need to use a 3core + earth cable… you mileage may vary depending on light unit…).
This way you can turn on power to the PIR and use it as normal for security, and the 2nd relay to over ride the PIR and have the light on all the time… or both off to turn the light completely off!
For the PIR sensor relay, you could get one which has a power meter built in, write a little smartapp which will alert you when the power jumps up past a specific amount to alert you when its on.
All true, but it’s also true that many people use the fibaro and other in wall relay successfully with LEDs. It depends very much on the specific load on the device. You just have to look at the device specs.
Also, the newest Fibaro model, the 213, does not have dry contacts, so it doesn’t run into quite the same issue with inrush current that the older 212 did. But it also requires a neutral wire.
